Patient Usually Complains Of
Patient presents with acute onset of left knee pain and mechanical symptoms following a twisting injury. Reports a sensation of "locking" or "catching" in the joint, with inability to achieve full terminal knee extension. Denies prior history of instability or trauma to the affected knee.
Clinical Examination Findings
Left knee examination reveals moderate joint line tenderness along the medial aspect. Significant limitation in passive and active extension (locked knee). Positive McMurray test for medial meniscus. Effusion present. Neurovascular status intact distally.
Treatment Protocol
Immediate referral for MRI of the left knee to confirm bucket-handle tear. Activity modification, non-weight bearing with crutches, and ice application. Surgical consultation for arthroscopic repair or partial meniscectomy indicated due to mechanical locking.
