Q

Body chart/location of symptoms for Iliotibial Band Syndrome

A

Can be felt:

  1. lateral from ITB rubbing on femoral condyle - causing local ache at lateral knee; crepitus or popping along the lateral knee
  2. medial knee causing sprain of MCL due to excessive rotation of tibia
  3. subpatellar due to patella being pulled laterally by ITB attachment

30
Q

A

-stretching, rest, NSAIDS

31
Q

32
Q

Bursitis ease factors

A

-ice, NSAIDS, rest

33
Q

OA/DJD profile/history

A

-overweight, older adult, family history of OA, weakness in gluteal muscles causing medial stress to knee; poor gait biomechanics
-may see genu varus at knee
-women > men
> 55 yrs old

34
Q

Profile/history of meniscal injury

A
  • chronic knee trouble, pain with squatting & stairs; will complain of pain with sit to stand
  • MOI usually involved slight flexion, compression (wt bearing through joint) with a rotational movement
35
Q

Which meniscus is more commonly torn?

A

-medial meniscus is more commonly torn due to valgus stress placed at the knee

36
Q

ACL mechanism of injury/history

A

-mechanism of injury is usually non-contact; involved a rotational stress of the tibia when the foot planted & pronated, force when the knee is extended causing an anterior translation of the tibia on the femur; often have quadriceps dominance over the hamstrings; increased Q angle; women > men

37
Q

PCL mechanism of injury/history

A

-mechanism of injury is usually from falling on a flexed knee (dashboard injury) or trauma; will have visible posterior sag; no inflammation will be present

38
Q

MCL mechanism of injury/history

A

-usually torn with a valgus stress to the knee, return from a jump, or rotational stress with the knee extended or slightly flexed; can also be torn with tibia plateau fractures

39
Q

LCL mechanism of injury/history

A

-mechanism of injury is a varus stress to the knee

40
Q

Possible reasons for patellofemoral dysfunction

A
  • patella alta; genu valgus; increased Q angle greater than 17 degrees; weakness in the gluteus medius muscle causing excessive internal rotation of the femur on the tibia; tight ITB; pronated feet (also associated with medial tibial rotation
  • insidious onset; sudden change in activity
41
Q

Iliotibial band syndrome history/mechanism of injury

A
  • overuse injuries (runners, downhill running)
  • training errors or poor biomechanics
  • weakness in gluteus medius muscle at the hip leading to excessive internal rotation of the femur
42
Q

Patellar tendonitis history/mechanism of injury

A

-history of overuse in eccentrically loading the quadriceps muscles (running, jumping, squatting)
-pain is increased during or following the sport or activity that stretched the tendon
-pain at mid to full squat range
gait observation: watch for excessive or late pronation

43
Q

Baker’s Cyst history/mechanism of injury

A

-chronic, ache or pain in the posterior leg, usually in athletes

44
Q

Pre-patellar history/mechanism of injury

A

-usually from a fall or excessive kneeling (cleaning)

45
Q

A

-Posterior Drawer Test; Posterior sag sign

56

Q

Patellofemoral dysfunction special tests

A

-Clarke’s Sign

58
Q

Special test for knee instability

A

-Apprehension test

59
Q

Iliotibial band syndrome special tests

A

-ITB Noble’s Test; Ober’s test

60
Q

Special tests for patellar tendonitis

A

61
Q

OE palpation findings for OA/DJD

A

-medial knee joint line may be painful upon palpation

62
Q

Palpation findings for meniscal injury

A

-tender to palpation over meniscus

63
Q

Ligament injury palpation findings

A

-MCL/LCL are on the outer border of the knee & palpable on the side corresponding with their name

64
Q

OE palpation findings for patellofemoral dysfunction

A

-pain with compression of the patella into the femoral condyles

65
Q

Iliotibial band syndrome palpation findings

A

-tightness palpable in the lateral leg; in women may notice a decrease in the normal curvature of the hips due to this tightness

66
Q

Patellar tendonitis palpation findings in the OE

A

-palpation over the patellar tendon; infra patellar region

67
Q

Baker’s Cyst palpation

A

-painful palpation over the posterior cyst in the popliteal fossa

68
