  https://my.clevelandclinic.org/health/diseases/5599-osteoarthritis

  Osteoarthritis is the most common type of arthritis. It happens when the cartilage that lines your joints is worn down or damaged and your bones rub together when you use that joint. A healthcare provider will help you find a combination of treatments to manage your symptoms. […] Osteoarthritis is the most common type of arthritis (a condition that affects your joints). Healthcare providers sometimes refer to it as degenerative joint disease or OA. It happens when the cartilage that lines your joints is worn down over time and your bones rub against each other when you use your affected joints. […] Usually, the ends of bones in your joints are capped in a layer of tough, smooth cartilage. Cartilage is like a two-in-one shock absorber and lubricant it helps the bones in your joints move past each other smoothly and safely. If you have osteoarthritis, the cartilage in your affected joints wears away over time. Eventually, your bones rub against each other when you move your joints.

  Osteoarthritis is a degenerative joint disease that can affect the many tissues of the joint. It is by far the most common form of arthritis, affecting more than 32.5 million adults in the United States, according to the Centers for Disease Control and Prevention. […] Osteoarthritis can degrade cartilage, change bone shape and cause inflammation, resulting in pain, stiffness and loss of mobility. […] Its signs and symptoms typically show up more often in individuals over age 50, but OA can affect much younger people, too, especially those who have had a prior joint injury, such as a torn ACL or meniscus. It typically develops slowly over time, but after such an injury, it can develop much more rapidly, within just a few years. […] Symptoms tend to build over time rather than show up suddenly. They include pain or aching in a joint during activity, after long activity or at the end of the day. Joint stiffness usually occurs first thing in the morning or after resting. Limited range of motion that may go away after movement. Clicking or popping sound when a joint bends. Swelling around a joint. Muscle weakness around the joint. Joint instability or buckling (as when a knee gives out).

  https://www.aafp.org/pubs/afp/issues/2012/0101/p49.html

  Osteoarthritis is a common degenerative disorder of the articular cartilage associated with hypertrophic bone changes. Risk factors include genetics, female sex, past trauma, advancing age, and obesity. The diagnosis is based on a history of joint pain worsened by movement, which can lead to disability in activities of daily living. […] The most common symptom of osteoarthritis is joint pain. The pain tends to worsen with activity, especially following a period of rest; this has been called the gelling phenomenon. Osteoarthritis can cause morning stiffness, but it usually lasts for less than 30 minutes, unlike rheumatoid arthritis, which causes stiffness for 45 minutes or more. Patients may report joint locking or joint instability. These symptoms result in loss of function, with patients limiting their activities of daily living because of pain and stiffness. […] Patients who have continued pain and disability from osteoarthritis of the hip, knee, or shoulder despite maximal medical therapy are candidates for total joint replacement.

  According to the CDC, about 80 percent of people with OA have some problem with range of motion. About 25 percent need assistance with daily living activities. […] Bone spurs are small bony projections. They can occur naturally, but they may also be a response to inflammation in a joint. Bone spurs, also called osteophytes, can sometimes be felt as hard little lumps around joints affected by OA. They are not painful in and of themselves. However, bone spurs can rub against nearby nerve and bone, causing additional pain. […] People with OA often have to exert extra physical effort in order to carry out the basic daily tasks of living. This can cause fatigue. […] Many people with OA hear sounds in their joints when they move. Their joints may make noises such as: creaking, snapping, crackling, grinding.

  For most people with OA, stiffness is worse in the mornings. It is usually also worse after periods of inactivity or rest. At these times, joints may feel: achy, rigid, hard to move. […] Soreness and aching pain are common symptoms of OA. Muscle pain can also occur in the surrounding tissue. Usually, pain, like stiffness, is most intense after sleep or a period of inactivity. […] Some people with OA feel more pain during movement of the joints and less pain when at rest. Over time, the pain may occur even when the joints are not used. […] Joint tenderness, sensitivity of the joints to touch, can also occur in people with OA. […] Swelling is more common in people with RA than OA. However, people with OA also experience swelling. Swelling is the body’s reaction to irritants, such as bone on bone contact. It contributes to the stiffness and pain experienced by patients with OA.

  Osteoarthritis (OA) is by far the most common type of arthritis. In OA, the cartilage in the joints (which covers the ends of the bones and allows free movement between them) becomes worn down. […] In other people, OA causes symptoms such as pain, stiffness, reduced joint motion, or changes in the shape of affected joints. […] The symptoms of OA usually begin after the age of 40 years and can vary considerably from one person to another. OA most commonly causes symptoms in the fingers, feet, knees, hip, and spine. […] The main symptom of OA is joint pain that is worse with activity and relieved by rest. […] Morning stiffness is a common symptom of OA. […] OA may cause joint swelling (called an effusion) from the accumulation of excess fluid in the joint. […] Movement of a joint affected by OA may cause a crackling or grating sensation called „crepitus.”

  https://my.clevelandclinic.org/health/diseases/21750-osteoarthritis-knee

  While there arent definitive stages of osteoarthritis in your knee, it is a degenerative condition that progresses in a predictable way. […] Knee pain is the most common symptom of knee osteoarthritis. Your knee might hurt when you put pressure on it, when you move it or even when youre sitting still. Other OA knee symptoms include: Your knee feels stiff, especially after you first get up or youve been sitting for a long time. Your knee is swollen or feels puffy. You hear a cracking or grinding noise when you move your knee. Your knee feels wobbly, as if it could buckle or give out. Your knee locks up or feels like its stuck when you try to move it. […] As knee arthritis progresses, it can cause some additional negative side effects, including: Joint instability. As you start to use your knees less, the muscles that support it can become weaker, making the joint less stable. This can affect how you walk and raise your risk of injury. Bone spurs. Loss of cartilage in your joint and friction on your bones can cause bony lumps called bone spurs to grow on them. These can cause more friction and irritation in your joint. Bakers cyst. When the synovial membrane that lines your joint capsule bulges through a tear in the capsule, it traps joint fluid in the bulge, forming a cyst at the back of your knee joint. Mood disorders. Having OA can raise your risk of anxiety and depression. New limitations, mobility challenges and chronic pain can all contribute. Your mood can also make these worse.

  https://www.nhs.uk/conditions/osteoarthritis/symptoms/

  If you have osteoarthritis in your knees, both your knees will usually be affected over time, unless it occurred as the result of an injury or another condition affecting only 1 knee. […] Your knees may be most painful when you walk, particularly when walking up or down hills or stairs. […] Osteoarthritis in your hips often causes difficulty moving your hip joints. […] You’ll also usually have pain in the groin or outside the hip. This is often worse when you move the hip joints, although it can also affect you when you’re resting or sleeping. […] Osteoarthritis often affects three main areas of your hand: the base of your thumb, the joints closest to your fingertips, the middle joints of your fingers. […] Your fingers may become stiff, painful and swollen and you may develop bumps on your finger joints. Over time, the pain may decrease and eventually disappear altogether, although the bumps and swelling can remain. […] In some cases, you may also develop a bump at the base of your thumb where it joins your wrist. This can be painful and you may find it difficult to perform some manual tasks, such as writing, opening jars or turning keys.

  As arthritis gets worse, it can cause joints to be swollen and tender. It may hurt when you press down on the joint. […] Stiffness may occur after prolonged sitting, after activity or when you wake up. Its a feeling that you need lubrication to do something, Cannada explains. Morning stiffness that lasts more than 30 minutes is a hallmark of RA. […] Grinding or grating as a joint moves is a sign the cartilage in your joint has worn down and can indicate arthritis, Cannada says. Its most common in the knee and hip but can affect other joints as well. […] Many cases of osteoarthritis occur in a part of the body that suffered a prior injury or trauma. If a football player had a knee injury back in high school, then theyre likely to get knee osteoarthritis later, Haque says. […] Many people dont realize pain from hip arthritis radiates to the groin, not the outside of the hip, Cannada says. Hip arthritis can also cause pain in your thigh or buttocks.

  Osteoarthritis of the cervical spine or lumbar spine causes pain in the neck or low back. Bony spurs, called osteophytes, that form along the arthritic spine can irritate spinal nerves, causing severe pain that can radiate from the spine as well as numbness and tingling in the affected parts of the body. […] Osteoarthritis causes the formation of hard, bony enlargements of the small joints of the fingers. Classic bony enlargement of the small joint at the end of the fingers is called a Heberden’s node, named after a famous British doctor. […] Osteoarthritis of the joint at the base of the big toe of the foot leads to the formation of a bunion. Osteoarthritis of the fingers and the toes may have a genetic basis and can be found in numerous female members of some families. […] The prognosis of patients with osteoarthritis depends on which joints are affected and whether or not they are causing symptoms and impaired function. Some patients are unaffected by osteoarthritis while others can be severely disabled. Joint replacement surgery for some results in the best long-term outcome. […] Osteoarthritis does not cause internal organ damage or blood test abnormalities.

  The bones of your spine and the discs in between are often affected by changes that are very similar to osteoarthritis. In the spine, these changes are often referred to as spondylosis. Although they are very common, they aren’t the most common cause of back or neck pain. […] Osteoarthritis of the foot generally affects the joint at the base of your big toe. However, osteoarthritis of the mid-foot is also quite common. The ankle is the least commonly affected part of the foot. […] The elbow joint isn’t commonly affected by osteoarthritis. When it is affected, it often follows either a single serious injury or a number of more minor injuries. […] The jaw, or temporomandibular joint, is one of the most frequently used joints in the body and the cartilage in this joint is particularly prone to wear. Osteoarthritis in the jaw often starts at an earlier age than in other joints.

[…] Osteoarthritis affects different people, and different joints, in different ways. But, for most people, osteoarthritis doesn’t continue to get steadily worse over time. […] For some people, the condition reaches a peak a few years after the symptoms start and then remains the same or may even improve. Others may find they have several phases of moderate joint pain with improvements in between. […] The degree of damage to a joint isn’t very helpful in predicting how much pain you’ll have. Some people have a lot of pain and mobility problems from a small amount of damage, while others have a lot of damage to the joint but few or no symptoms. […] If you have severe osteoarthritis, you may find some of your daily activities more difficult depending on which joints are affected. More severe osteoarthritis can also make it difficult to sleep.

  https://healthmatch.io/osteoarthritis/how-fast-does-osteoarthritis-progress

  Osteoarthritis (OA) is characterized by the breakdown of cartilage in the joints, which worsens over time. Cartilage is the tissue between bones of a joint that lubricates the bones and provides adequate cushioning. When this tissue breaks down, the bones rub against each other, resulting in pain, swelling, and decreased function. […] Osteoarthritis is a degenerative joint disease, meaning it gradually progresses to the more advanced stages as the cartilage degeneration worsens. […] Experts confirm that once OA starts, it may take years to reach a severe stage. However, in extreme cases, OA progresses rapidly to complete the destruction of the cartilage within a few months. […] A recent study reveals that OA of the knee tends to progress faster in older persons and those with OA in more than one joint. It also progresses much faster in people with a high BMI. If you suspect you have osteoarthritis, it is crucial that you visit your doctor immediately. Early diagnosis and treatment can help slow down the progression of OA.

  https://healthmatch.io/osteoarthritis/how-fast-does-osteoarthritis-progress

  There are several stages of OA, and it is important to know the signs and symptoms of each so you can take steps to alleviate the symptoms and slow down the disease progression. […] An OA is classified as severe if the pain and limited movement has become a constant issue. At this point, X-ray images show virtually no space between the joint bones, meaning the bones have started rubbing against each other every time you move. […] OA is a degenerative condition that gets worse with age. Osteoarthritis onset usually occurs after the age of 40; and by 65 years of age, most people with OA could have moved several stages towards the severe stage. […] The best chance to stop or slow down the rate of OA progression is through early diagnosis and treatment. Additionally, maintaining a healthy lifestyle through dietary changes, exercise, adequate sleep, and managing stress can slow down the progression substantially.

  Unlike other types of arthritis, pain and joint swelling increase slowly over time as the disease progresses through the osteoarthritis stages: Stage 0 No signs of disease. The joint cartilage between your bones is healthy. Stage 1 Cartilage starts to erode and growths on the end of your bones (bone spurs) could begin to form. It may hurt to bend and straighten your joint, but you may not feel it for years. Stage 2 The space between your bones may get smaller as the cartilage reduces, you have bone spurs, and your joints begin to ache after being active. Stage 3 There is less space in the joint from the loss of cartilage and you are experiencing more pain as you move. The bones change and become thicker, denser, and deformed. More bone spurs have developed, and fluid buildup has caused an increase in swelling. Stage 4 There is little to no cartilage in your joint, bone spurs are much larger, and the ends of the bones are more rigid and deformed. This is the most extreme stage of the disease.

  Osteoarthritis is a progressive condition, which means symptoms may spread to other parts of your body. Having osteoarthritis in one part of your body may also increase your risk of developing the condition in other body parts, according to the Arthritis Foundation. […] Osteoarithis is a progressive condition that may be classified into four stages. This may depend on the severity of your symptoms and the degree of joint and cartilage damage. The four stages of osteoarthritis are: Stage 1 (Mild): You may experience early symptoms of osteoarthritis, but your cartilage is still in good shape. Stage 2 (Moderate): You may experience sharp, acute symptoms. Your cartilage is showing signs of wear and tear. Stage 3 (Advanced): You may experience constant osteoarthritis symptoms, especially when you apply weight to the affected joint. The joint cartilage is also almost completely gone. Stage 4 (Severe): This is the most severe form of osteoarthritis. You may experience: severe pain, stiffness, and inflammation, decreased range of motion, joint instability, such as sudden locking or buckling, other symptoms, such as muscle weakness, bone spurs, and joint deformity. During stage 4 osteoarthritis, you’ll likely need surgery to reduce your symptoms and increase mobility, function, and quality of life.

  At Stage 3, patients often report persistent discomfort while moving, accompanied by noticeable joint swelling. This stage of osteoarthritis typically reflects a greater level of cartilage breakdown, making daily activities more challenging due to increased stiffness and pain. […] Stage 4 osteoarthritis (OA) is characterized by significant joint deterioration. Cartilage loss becomes severe, often leading to the bones rubbing against each other, which results in extreme pain, inflammation, and visible joint deformity. […] Patients frequently experience constant discomfort that severely limits mobility and affects everyday activities. […] Osteoarthritis (OA) primarily results from the progressive breakdown of articular cartilage. In the early stages, particularly Stage 1, the delamination and slight wear occur due to minor mechanical stress, leading to cartilage degradation and enhanced production of enzymes that exacerbate damage.

  Osteoarthritis (OA) usually progresses slowly over a period of months or years. Early on, osteoarthritis symptoms tend to come and go. Over time, as damage accumulates, symptoms can become more constant, occurring at rest and disturbing sleep. […] Osteoarthritis affects everyone differently, however common symptoms include joint pain, aching, morning stiffness lasting less than 30 minutes, reduced range of movement in the affected joint(s) and possibly swelling. The symptoms may come and go, but the intensity of pain can increase over time since osteoarthritis progresses over time. […] Your joint may hurt during heavy use, and improve with rest.

  Arthritis can cause a wide array of symptoms, such as pain, swelling, and stiffness. The severity of arthritis symptoms is not directly associated with the extent of joint damage, particularly in the early stages of osteoarthritis. An x-ray may show mild joint degeneration, and the joint may cause notable pain or no symptoms at all. […] Even at its later stages, osteoarthritis symptoms are unpredictable. It is possible to have „bone-on-bone osteoarthritis” and have mild or no symptoms. It is unclear why these differences exist. […] Reported joint pain from osteoarthritis ranges from dull and aching to sharp and piercing. The pain may worsen during movement. It is also possible for the pain to lessen during activity and then worsen after the activity ends, as joints cool down. […] As symptoms progress, the pain may be felt almost constantly. In addition, the joint may feel painful when the skin over it is pressed (tenderness).

Some of the common symptoms include: stiffness, pain associated with movement, joint swelling, muscle weakness, joint instability, reduced range of movement, sounds within the joints. […] If you have osteoarthritis it is important to know about how to manage your pain, including how to pace and plan your daily activities. […] Use of pain-relieving medication to manage osteoarthritis focuses on improving symptoms, not changing the disease process itself. […] Exercise is an important and effective part of any osteoarthritis management plan. It can help to reduce your pain and increase your level of mobility. […] In most cases of osteoarthritis surgery is not required. However, if you have tried all non-surgical treatments options without success, and you are still experiencing significant pain and loss of function, then surgery may be an option.

  The aim of this study was to identify modifiable clinical factors associated with radiographic osteoarthritis progression over 1 to 2 years in people with painful medial knee osteoarthritis. […] Radiographic osteoarthritis progression occurred in 58 participants (12%). Clinical factors independently associated with radiographic progression were the use of NSAIDs, adjusted odds ratios (OR) and 95% confidence intervals (CI) 2.05 (95% CI 1.1 to 3.8), and not meeting physical activity guidelines, OR 2.07 (95% CI 0.9 to 4.7). […] Among people with mild radiographic knee osteoarthritis, people who use NSAIDs and/or do not meet physical activity guidelines have a greater risk of radiographic osteoarthritis progression. […] Radiographic OA progression over 1 to 2 years occurred in 58 (12%) participants. Results of this longitudinal study show that people who used NSAIDs and those who did not meet physical activity guidelines independently had double the odds of radiographic knee OA progression compared to people who did not. […] The strongest risk factors for radiographic OA progression were baseline structural disease severity measures, indicating that once OA is clearly established on x-ray, OA progression is likely.

  Osteoarthritis occurs when the cartilage and other surrounding tissue in the joint breaks down or wears away. Although not all older adults will develop osteoarthritis, age is a contributing factor. Other factors that can cause damage to the cartilage include: Congenital diseases that cause an imbalance in the joints. Inherited conditions that cause a buildup of iron, calcium, or copper in the body. Bone disorders that affect the joints. Nervous system diseases or disorders that result in the loss of nerve function. […] The general risk factors and complications associated with osteoarthritis include: Aging Risk of developing osteoarthritis increases with age. Decreased estrogen Postmenopausal women over the age of 55 have an increased risk of osteoarthritis, especially in the knee. Diabetes Elevated blood sugars increase free radicals in the body, causing oxidative stress that exceeds the resilience of the cartilage on a cellular level. Hyperlipidemia High cholesterol or elevated lipids contribute to the inflammatory response in the body, and oxidation of lipids can create deposits in the cartilage that affect the blood flow of the subchondral bone. Obesity or being overweight Creates excess pressure on the body, especially the knees, hips, joints of the feet, and lower back. History of surgery or an injury to a specific joint. Overuse or repetitive movements. Joints that did not form correctly during development. Family history History of osteoarthritis or other inflammatory arthritis.

  By Stage 2, this degradation becomes more pronounced, showing osteophytes and narrowing joint space. As the disease advances, particularly in Stage 3 and Stage 4, significant cartilage loss occurs, resulting in bones rubbing against each other, structural changes in the joint anatomy, and inflammation, further hampering mobility. […] Inflammation significantly contributes to OA’s worsening condition. Immune cells within the joint produce inflammatory cytokines, such as TNF- and IL-6, which amplify the catabolic processes of cartilage destruction. […] Osteoarthritis development is influenced by numerous risk factors, including age, obesity, previous injuries, and genetics. […] Yes, osteoarthritis (OA) can progress differently in various parts of the body due to several factors. Each joint may experience a unique progression rate influenced by individual characteristics such as genetics, obesity, age, and previous injuries. […] Recent studies emphasize the critical role of inflammation in osteoarthritis (OA) progression. Inflammatory markers such as TNF-alpha and IL-6 are increasingly recognized as contributors to cartilage degradation and joint damage.

  https://www.nature.com/articles/s41584-022-00749-9

  Osteoarthritis (OA) is a progressive degenerative disease resulting in joint deterioration. Synovial inflammation is present in the OA joint and has been associated with radiographic and pain progression. […] Imaging studies suggest that synovial inflammation may be present in both early osteoarthritis (OA) and advanced-stage OA and is involved in the development and progression of OA. […] Synovial cells coordinate the production of molecules that initiate and maintain synovial inflammation and contribute to cartilage damage during OA progression. […] There is a need for functional imaging and cellular and molecular studies, together with a more robust histological interpretation at different stages of OA, to better stratify patients with OA and understand the role of synovitis in OA onset and progression.

  Osteoarthritis (OA) results from an imbalance between breakdown and repair of the tissues in the synovial joints. Risk factors include trauma, overuse, obesity, and genetic predisposition. The etiopathogenesis of osteoarthritis has been divided into 3 stages. […] In stage 1, proteolytic breakdown of the cartilage matrix occurs. Chondrocyte metabolism is affected, leading to an increased production of enzymes, which includes metalloproteinases (eg, collagenase, stromelysin) that destroy the cartilage matrix. Chondrocytes also produce protease inhibitors, including tissue inhibitors of metalloproteinases (TIMP) 1 and 2, but in amounts insufficient to counteract the proteolytic effect. […] Stage 2 involves the fibrillation and erosion of the cartilage surface, with a subsequent release of proteoglycan and collagen fragments into the synovial fluid.

  In stage 3, the breakdown products of cartilage induce a chronic inflammatory response in the synovium. Synovial macrophage production of metalloproteinases, as well as cytokines such as interleukin (IL) 1, tumor necrosis factor (TNF)-alpha, occurs. These can diffuse back into the cartilage and directly destroy tissue or stimulate chondrocytes to produce more metalloproteinases. Other proinflammatory molecules (eg, nitric oxide [NO], an inorganic free radical) may also be a factor in stage 3. […] Eventually, the above events alter the joint architecture, and compensatory bone overgrowth occurs in an attempt to stabilize the joint. As the joint architecture changes and further mechanical and inflammatory stress occurs on the articular surfaces, the disease progresses unchecked.

  Radiographs are a commonly used tool to assess disease progression in osteoarthritis (OA). However, it is not the preferred method of defining and following OA progression. […] MRI offers a much better assessment, and OA features are much better targeted for defining and following the disease progression. Using MRI, cartilage volume/thickness loss predicts knee replacement and has similar levels of sensitivity to discriminate treatments in clinical trials. […] In addition to cartilage, another MRI target for diagnosis and assessment of OA progression is subchondral bone alterations, especially bone marrow lesions (BMLs). BMLs independently predict OA outcomes including knee replacement and are sensitive to progression. […] MRI assessment of cartilage morphology is now recommended for the evaluation of disease progression as an endpoint for clinical trials.

  Rate of cartilage loss is a good measure of progression as it predicts risk of knee replacements. […] Cartilage thickness has also been used to assess rates of disease progression, and data demonstrate that both the measurement of cartilage thickness and that of volume provide the same level of sensitivity to estimate cartilage loss in a clinical trial. […] BMLs predict site-specific progression of knee JSN in those with symptomatic knee OA. […] Moreover, a combination of cartilage damage and BMLs was associated with progression of JSN. […] The presence of MRI-detected effusion or synovitis predicts knee replacement. […] Data also showed that chondroitin sulphate, a symptomatic slow acting drug for osteoarthritis (SYSADOA) with DMOAD activity, at 6 months in patients concomitantly taking NSAIDs, significantly reduced the synovial membrane thickness compared to the placebo group, in addition to decreasing cartilage volume loss.

  Osteoarthritis is a chronic joint disease. It affects mostly middle-aged and older adults. […] Common symptoms include pain, stiffness, and limited movement of joints. […] The most common symptom of OA is pain after overuse or inactivity of a joint. Symptoms usually happen slowly over years. Symptoms can occur a bit differently in each person. They may include: Joint pain, Joint stiffness, especially after sleep or inactivity, Less movement in the joint over time, A grinding feeling in the joint when moved, as the cartilage wears away (in later stages). […] Because OA causes joints to get worse over time, it can cause disability. It can cause pain and movement problems. These can make you less able to do normal daily activities and tasks. […] Although there is no cure for OA, it’s important to help keep joints working. You can ease pain and inflammation. Work on a treatment plan with your healthcare provider. The plan may include medicine and therapy. Work on lifestyle changes that can improve your quality of life.

  Some people find that their symptoms are worse at night, in cold and/or damp weather. Symptoms can come and go, varying in severity according to your activity levels and the weather. In severe cases of osteoarthritis, symptoms can be continuous. […] Osteoarthritis usually doesn’t worsen over time or cause disability. In many cases, osteoarthritis is mild and you can remain as active as others your age who don’t have osteoarthritis. […] However, in cases where osteoarthritis is severe, one or more joints can be badly affected and your mobility may be significantly reduced for your age. […] Osteoarthritis usually flares up in response to activity. Some people find pain is worse at night and stiffness is worse in the morning. Cold and/or damp weather can also worsen symptoms. […] End-stage osteoarthritis occurs when the cartilage of your affected joints has completely worn away and you have multiple bone growths (spurs) on the edges of your joint bones. In some cases, this may cause joint deformities and you may need surgery to relieve your symptoms.

  Osteoarthritis is the most common form of arthritis in the world. Classically, osteoarthritis presents with joint pain and loss of function; however, the disease is clinically very variable and can present merely as an asymptomatic incidental finding to a devastating and permanently disabling disorder. […] The presentation and progression of osteoarthritis vary greatly from person to person. The triad of symptoms of osteoarthritis is joint pain, stiffness, and locomotor restriction. Patients can also present with muscle weakness and balance issues. Pain is typically related to activity and resolves with rest. In those patients in whom the disease progresses, pain is more continuous and begins to affect activities of daily living, eventually causing severe limitations in function. […] The prognosis for osteoarthritis patients depends on which joints are affected and the level of symptomatology and functional impairment. Some patients remain relatively unaffected by osteoarthritis, while others can experience severe disability. In some cases, joint replacement surgery offers the best long-term outcome.
