Joint replacement
Although the prevalence of knee OA is greater in adults who have engaged in occupations that require repetitive bending and strenuous activities, an association with regular, intense exercise remains controversial. joint replacement Thoracic back pain. While early studies in joggers failed to find a higher prevalence of OA of the knee in joggers compared to non-joggers, a recent study of the Framingham data base in elderly adults provided the first longitudinal association between high level of physical activity and incident knee OA. Low-impact and recreational exercises are unlikely to constitute a risk factor for knee OA, and are likely to benefit the cardiovascular system. Prior menisectomy is a significant risk factor in men for the development of OA in the knee. joint replacement Psoriasic-arthritis. (top of page) Signs and Symptoms of OA OA is diagnosed by a triad of typical symptoms, physical findings and radiographic changes. The American College of Rheumatology has set forth classification criteria to aid in the identification of patients with symptomatic OA that include, but do not rely solely on, radiographic findings. (ACR Guidelines-Clinical Classification criteria for OA of the Hip) (ACR Guidelines-Clinical Classification criteria for OA of the knee) Patients with early disease experience localized joint pain that worsens with activity and is relieved by rest, while those with severe disease may have pain at rest. joint replacement Rheumatoid arthritis diagnosis. Weight bearing joints may "lock" or "give way" due to internal derangement that is a consequence of advanced disease. Stiffness in the morning or following inactivity ("gel phenomenon") rarely exceeds 30 minutes. Physical findings in osteoarthritic joints include bony enlargement, crepitus, cool effusions, and decreased range of motion (slide). Tenderness on palpation at the joint line and pain on passive motion are also common, although not unique to OA. Radiographic findings in OA (slide) include osteophyte formation, joint space narrowing, subchondral sclerosis and cysts. The presence of an osteophyte is the most specific radiographic marker for OA (ACR Guidelines-Clinical Classification criteria for OA of the knee) although it is indicative of relatively advanced disease. (top of page) Differential Diagnosis If a patient has the typical symptoms and radiographic features described above, the diagnosis of OA is relative straightforward and is unlikely to be confused with other entities. However, in less straightforward cases, other diagnoses should be considered. For example, periarticular pain that is not reproduced by passive motion or palpation of the joint should suggest an alternate etiology such as bursitis, tendonitis or periostitis. If the distribution of painful joints includes MCP, wrist, elbow, ankle or shoulder, OA is unlikely. Prolonged stiffness (greater than one hour) should raise suspicion for an inflammatory arthritis such as rheumatoid arthritis.
