3. clinical evaluation of the knee • Fundamental tool to diagnosis and treatment, and should never be replaced by the findings retrieved by the imaging studies . • The introduction of highly effective imaging tools like and MRI has stolen the central role of clinical evaluation, so that there's a common feeling, between patients but also between surgeons, that the diagnosis of a thorn meniscus or a ruptured ACL has to be ruled out only on the basis of an imaging study. • But the efficacy of a correct clinical examination needs not to be forgotten.

4. HISTORY • Chief complain • Present illness • Past history • Family history

5. General Approach • History • look • Feel • movement • Muscular and neurovascular exams • Special test

6. History • mechanism of injury • Duration of complaint • Location, nature of symptoms • Exacerbating or relieving maneuvers

7. Key Questions in the History • Mechanism of Injury? • Acute or Chronic? • Location and level of pain? • Able to walk? • Mechanical Symptoms? (Locking, popping, catching?) • Associated instability? • Swelling? • Exacerbating or relieving maneuvers? • Previous injuries or surgeries?

8. activity level (IKDC score) • I - Strenuous activity(contact sports involving pivoting and cutting) • II - Moderate activity(pivot sports without contact; manual work) • III - Light activity(jogging, running) • IV - Sedentary activity

9. SIGNS AND SYMPTOMS • 1.Pain • 2. Laxity • 3.Locking: a:True locking b: False locking • 4.Effusion

10. Clinical Examination • 1) patello-femoral joint/extensor mechanism • 2) articular (meniscal and chondral) lesions • 3) knee instability

11. Patello-Femoral Joint • Q Angle • Patellar Tilt and Glide • Patella tracking • J sign

12. Diagnosis of a meniscal tear • Joint line tenderness: • Most important physical finding is localized tenderness along the medial or lateral joint line or over the periphery of the meniscus. This most often is located osteromedially or posterolaterally, • Diagnostic accuracy rate 89%

13. Meniscal Palpation TestsMcMurray Test

14. Meniscal Rotation TestsApley's (grinding) test

15. Meniscal Rotation Tests Squat test

16. Meniscal Rotation Tests Thessaly test • Diagnostic accuracy rate: • 94%medial meniscus • 96% lateral meniscus.

17. sensitivities and specificities • McMurray, 70% and 71% • Apley, 60% and 70% • joint line tenderness, 63% and 77%

18. Abduction (Valgus) Stress Test

19. Adduction (Varus) Stress Test

20. Varus and Valgus Stress Tests Varus stress test Valgus stress test

21. Cabot's manoeuvre

22. Lachman Test

23. Anterior Drawer test

24. Posterior drawer test

25. Doorstop effect

26. Posterior Tibia Sag

27. Quadriceps Active Test

28. Slocum Anterior Rotary Drawer Test • positive anterior drawer test result in neutral tibial rotation that is accentuated when the test is repeated in 30 degrees of external tibial rotation and reduced when it is performed with the tibia in 15 degrees of internal rotation indicates anteromedial rotary instability. The opposite indicates anterolateral rotary instability.

29. Center of rotation

30. lateral pivot shift testof Macintosh

31. Jerk Test of Hughston and Losee

32. Flexion-rotation drawer test

33. Flexion-Rotation Drawer Test (Noyes)

34. External Rotation-Recurvatum Test

35. Reverse Pivot Shift Sign

36. Tibial External Rotation (Dial Test) • Increased external rotation at 30 degrees that decreases at 90 degrees indicates isolated injury to posterolateral corner. • increased external rotation at both 30 and 90 degrees indicates injury to both PCL and posterolateral corner.
