42
Clark's sign (Patellar grind test)
``` Pt supine with knees supported Use web of hand, press down proximal to superior pole Pt contracts quad Positive if crepitus or pain -Questionable chrondromalacia patella ```
43
Measure Q angle
``` Higher Q angle leads to higher likelihood of lateral tracking Pt supine with knee full extension Fulcrum on patella Stationary arm ASIS Movement arm Tibial tubercle ```
44
Patellofemoral Joint Apprehension test
Lateral patellar gilde: -Pt with knees in full extesion -Thumbs on medial border of patella push lateral -Test repeated at 20 and 45 degrees Positive if patella glides laterally >1/4 its width Medial Patellar glide: -same as above but pushing medial Positive if patella glides >30-40% of width or >10mm
45
Figure 4 Test
- Pt supine and places ankle of affected knee on contralateral knee - Examiner pushes affected knee towards table - Positive is concordant pain over lateral joint line at popliteal hiatus indicates lateral meniscus tear
46
Payr's signs
Figure 4 test but patient complains of medial knee pain | Indicates posterior horn lesion of medial meniscus
47
Squat test/Duck waddle/Childress test
- Pt standing then squats - If no pain, duck walks in squat - Positive if a block preventing full flexion or pain at end range flexion indicates meniscal tear
48
Dynamic Test
-Pt supine with hip abd 60, flexed 45, and ER; knee flexed to 90, lateral border of foot on table -Palpate lateral joint line then slowly adduct the hip while maintaining flx -Positive if sharp pain at end of hip add or increase in pain Indicates lateral meniscal tear
49
Thessaly Test at 5 degrees
- Pt stands on one leg and grasps examiners hands - Pt flexes knee to 5 degrees and rotates R and L - Repeat R to L motion 3 times - Positive if joint line discomfot and sense of locking or catching - Indicates meniscal tear
50
Thessaly test at 20 degrees (Disco Test)
- Pt stands on one leg and grasps examiners hands - Flexes knee to 20 degrees and rotates R and L 3 times - Positive if joint line discomfort and sense of locking or catching - Indicates a meniscal tear
51
McMurray Click Test
Pt supine examiner stand on involved side Grasp at heel, flex knee to end range while palpating medial and lateral joint line -ER and extend knee to asses medial meniscus -IR and extend knee to assess lateral meniscus Positive if audible or palpable thud or click
52
Apley's test
Pt prone Examiner places knee on HS of pt with pt knee flx to 90 Grasp foot w/ both hands, distract tibia and rotates tibia -Positive if pain with rotation indicates soft tissue rotation sprain Examiner compresses tibia and rotates -Positive if worse with compression than distraction indicitive of meniscal tear
53
Valgus Stress Test
Pt supine with hip slightly ABD Knee flexed to 30 Examiner applies medially directed force at lateral joint line while hand at ankle slightly ER lower leg Repeat the test at full extension -Positive if excessive medial opening and concordant pain implicates MCL -If the test is positive at 0 degrees then the ACL/PCL and/or joint capsule is implicated
54
Varus Stress Test
Pt supine with hip slightly ABD Knee flexed to 30 Examiner applies laterally directed force at medial joint line while hand at ankle slightly IR the lower leg Repeat test with full extension -Positive if excessive lateral opening and concordant pain implicates LCL -If the test is positive at 0 degrees then the ACL/PCL and/or joint capsule is implicated
55
Posterior Sag Sign (Godfrey's Test)
Pt supine with hip and knee flexed to 90 degrees Examiner or chair supports leg under calf/heel Positive if posterior sagging of the tibia secondary to gravitational pull implicates PCL
56
Posterior Draw test
Pt supine with knee flexed to 90, hip flexed to 45, and neutral foot Examiner sits on pt foot to stabilize Both hands on proximal anterior tibia with thumbs on medial and lateral joint lines Proximal tibia is translated posteriorly Repeat with foot IR and ER -Positive dependent on motion compared to other side implicates PCL Grades 1-3 with 3 being most lax
57
Anterior Draw test
Pt supine with knee flx to 90 so foot is flat Examiner sits on foot and grasps behind proximal tibia w/ thumbs on tibial plateau Anterior tibial force applied Positive if greater anterior displacement when compared to unaffected side implicates ACL
58
Lachman's test
Pt supine with knee flexed to 15 degrees Examiner stabilizes distal femur with one hand and grasps proximal tibia with other Examiner applies anterior force to tibia Positive if greater anterior displacement on affected side when compared bilaterally Implicates ACL
59
Hughston's Test
Pt hooklying knee at 90 with 10 degrees IR/ER Examiner sits on patients foot Apply posterior forces moving tibia on femur while palpating joint line Excessive motion with IR is Posteromedial Rotary Instability Excessive motion with ER is Posterolateral rotary instability
60
Slocum Tests
Pt hooklying with knee at 90 with IR/ER Examiner sit on foot Apply anterior force of tibia on femur while palpating joint line Excessive motion with IR is Anterolateral rotary instability (greatest at 30 degrees IR) Excessive motion with ER is Anteromedial rotary instability (greatest at 15 degrees ER)
61
Pivot Shift (Test of Macintosh)
Pt supine Position LE in 10-15 degrees flexion and IR tibia and apply a valgus force with hand along lateral joint line Slowly flex knee beyond 30 maintaining rotation Positive if audible or palpable click or thud Rotary instability
62
Reverse Pivot Shift (Jakob test)
-Pt lies supine with knee flexed to 70-80 with ER of tibia -Gravitiy assists the knee into extension as examiner leans slightly against the foot and provides valgus force -As the knee approaches 20 degrees flexion, you can feel and see lateral tibial plateau move anteriorly from a posterior subluxation -Positive test is a reduction of the tibial head Rotary instability
63
Ober's Test
Pt sidelying, hip and knee flexed PT extends and ABD upper leg passively Allow the leg to lower towards table while stabilizing pelvis Performed with knee flexed and extended Positive if leg remains ABD, contracture of ITB is present
64
Nobel Compression Test
Pt supine with knee flexed to 90 and hip flexed PT applies pressure over lateral femoral condyle or 1-2 cm proximal Pt extends knee while PT maintains pressure Positive if PT reports extreme pain over lateral femoral condyle at 30 of flexion = ITB friction syndrome
