IT Band Tendonitis in the Knee

Near the outer knee, the IT band passes over tissues that move as the knee bends and straightens. When the current activity load exceeds what the area can tolerate, pain may build during a run, cycle, hill, or repeated stair session. It may be sharp at a particular angle, tender to touch, or followed by an ache after activity. The knee may otherwise look normal. Other causes of outer-knee pain include meniscus, ligament, joint, muscle, or nerve problems, so the term tendonitis should not be assumed from location alone. A physical examination helps identify the pain source.

Pause or shorten the activity that reliably triggers pain, particularly downhill running and abrupt training increases. Keep low-load movement only if it remains comfortable during and after the session. [Physiotherapy](/treatments/physiotherapy-and-rehabilitation/physiotherapy/) can combine symptom-guided loading with hip, thigh, and trunk strengthening. [Strength Training Rehabilitation](/treatments/physiotherapy-and-rehabilitation/strength-training-rehabilitation/) supports a gradual return to forceful activity. [Shockwave Therapy](/treatments/physiotherapy-and-rehabilitation/shockwave-therapy/) or [PRP Injection](/treatments/non-surgical-orthopedics/prp-injection/) may be options for selected persistent tendon conditions, not automatic treatments for every outer-knee pain pattern.

Arrange care if symptoms persist after modifying load, prevent normal walking, or return every time you resume sport. Seek prompt medical attention for a locked knee, inability to bear weight, a hot or very swollen joint, fever, major injury, or sudden loss of strength or sensation. Your clinician can assess the knee and nearby hip, decide whether imaging is useful, and check whether a different diagnosis needs treatment. A clear diagnosis matters before selecting an intervention.

Is the painful point the IT band or another knee structure? What activity can I continue safely? Which strengthening stage should I begin with? What criteria should guide my return to running or hills?
