Compensation for weak gluteus medius


1. Excessive lateral pelvic tilt (Trendelenburg):

Areas that may be affected due to compensation: Lumbar spine, sacroiliac joint (SIJ), greater trochanter bursa, insertion of muscle on greater trochanter, overactivity of piriformis and tensor fascia lata (TFL) .

2. Medial knee drift:

Areas that may be affected due to compensation: Lateral tibiofemoral compartment (via compression), patellofemoral joint, patella tendon and fat pad, pes anserinus, iliotibial band (ITB)

3. Lateral knee drift:

Areas that may be affected due to compensation: Medial tibiofemoral compartment (via compression), ITB, posterolateral compartment, popliteus

4. Same-sided shift of trunk (lateral flexion of trunk):

Areas that may be affected due to compensation: Lumbar spine (increased disc and facet joint compression), SIJ (increased shear)
