  3. 3. PAIN,DEFORMITY & DEPRESSION
  4. 4. NORMAL ANATOMY:KNEE JOINT <ul><li>Knee is a complex synovial joint formed between femoral condyles,tibial condyles & patella. </li></ul><ul><li>Stabilised by variety of ligaments. </li></ul><ul><li>Active movement at the knee are flexion,extension,medial rotation & lateral rotation. </li></ul>
  5. 5. OA-Risk Factors <ul><li>Age </li></ul><ul><li>Strongest risk factor </li></ul><ul><li>OA can start in young adulthood Risk increases with age </li></ul><ul><li>Female Gender </li></ul><ul><li>Affects more women than men </li></ul><ul><li>In men commonly before age 45, women after age 45 </li></ul><ul><li>Joint Alignment </li></ul><ul><li>Abnormal alignment or motion predisposes joint to OA </li></ul><ul><li>Bow legs, dislocations </li></ul>

  7. 7. IF RISK FACTORS CONTINUES……….
  8. 8. So Osteoarthritis is……… <ul><li>Osteoarthritis is a degenerative , noninflammatory joint disease characterised by destruction of articular cartilage and formation of none at the joint surfaces & margins . </li></ul>
  9. 9. CLINICAL FEATURES <ul><li>- Pain : Steady/intermittent in a joint - Stiffness : follows periods of inactivity, such as sleep or sitting </li></ul><ul><li>- Swelling/tenderness : in one or more joints </li></ul><ul><li>- Crepitus : Crunching feeling or sound of bone rubbing on bone </li></ul><ul><li>- Locking </li></ul><ul><li>- Limitation of movements </li></ul><ul><li>- Deformity : valgus/varus </li></ul>
  10. 10. Sequence of pathological events <ul><li>Disease process usually begins in anteromedial compartment of knee </li></ul><ul><li>Fibrillation d/t loss of water of wt. bearing articular cartilage </li></ul><ul><li>This puts pressure on underlying bone which causes sclerosis </li></ul><ul><li>Cysts& microfracture </li></ul><ul><li>New bone & osteophyte formation </li></ul>
  11. 11. <ul><li>Function of Articular Cartilage </li></ul><ul><li>Reduce friction at the joint </li></ul><ul><li>Act as a cushion to absorb the shock associated with joint use </li></ul><ul><li>Transmit weight loads to the underlying bone. </li></ul>
  12. 12. Development of O.A. <ul><li>imbalance between the destructive and reparative or synthetic processes of the articular cartilage </li></ul>
  13. 13. Mechanical axis of knee
  14. 14. Mechanical explanation of O.A. knee <ul><li>The mechanical axis of the knee is a line extending from the center of the hip joint  to the middle of the ankle joint. This line is practically perpendicular to the ground. </li></ul><ul><li>In a healthy, well aligned knee joint, the mechanical axis  passes through the middle of the knee. </li></ul><ul><li>Only when the mechanical axis passes through the center of the knee joint, the stresses on the knee joint surfaces are uniform in all areas of the joint and well balanced. </li></ul><ul><li>In many knee joint diseases, the mechanical axis is disturbed and does not pass through the center of the joint . This disturbance results in the overload of distinct areas of the knee joint leading to their damage . The patella lies not symmetrically in its groove. </li></ul>
  15. 15. <ul><li>Views </li></ul><ul><ul><li>Standing anteroposterior (weight bearing) </li></ul></ul><ul><ul><li>Lateral </li></ul></ul><ul><ul><li>Notch patellar views (Sunrise view) </li></ul></ul><ul><ul><ul><li>Posteroanterior intracondylar (PAIC) </li></ul></ul></ul><ul><ul><ul><li>Tangential patellar </li></ul></ul></ul><ul><li>Findings </li></ul><ul><ul><li>Joint space narrowing </li></ul></ul><ul><ul><ul><li>Medial tibiofemoral joint space narrowing </li></ul></ul></ul><ul><ul><ul><li>Patellofemoral joint space narrowing </li></ul></ul></ul><ul><ul><ul><li>Lateral joint space narrowing to lesser extent </li></ul></ul></ul><ul><ul><li>New subchondral bone formation </li></ul></ul><ul><ul><li>Tibia lateral subluxation </li></ul></ul><ul><ul><li>Osteophyte formation </li></ul></ul><ul><ul><ul><li>Medial osteophytes are most prominent initially </li></ul></ul></ul>RADIOLOGICAL EXAMINATION
  16. 16. STAGES OF OSTEOARTHRITIS <ul><li>   </li></ul><ul><li>The best way to see if osteoarthritis is present and see the severity is by looking at x-rays of the knee. Osteoarthritis is classified into 5 stages or &quot;Grades&quot;: </li></ul><ul><li>Grade 0:      · Normal knee joint      · No loss of cartilage and no deformation Grade 1:      · Some loss of articular cartilage      · If severe loss of cartilage, joint space narrows      ·  Osteophytes  may be seen Grade 2:      · More activity in the bone under the cartilage      · Increased activity can lead to bone hardening (sclerosis) and cysts      · Change in bone density (whitening of bone on x-ray) Grade 3:      · Some deformations on edge of bone      · Rough edges      · Increased joint narrowing Grade 4 :      · Complete loss of joint space      · Definite deformity of bone ends      · Changes in joint shape mean the bone contour has been altered </li></ul>
