Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with acute onset of right knee pain and instability following a direct blow to the proximal tibia while the knee was in a flexed position (dashboard-type injury). Reports localized posterior knee pain, swelling, and difficulty with weight-bearing. Denies neurovascular compromise or distal paresthesia.
Clinical Examination Findings
Right knee exam reveals significant posterior sag sign. Posterior drawer test is positive (Grade III) with loss of firm endpoint. Lachman and pivot shift tests are negative. Neurovascular status is intact with palpable distal pulses and normal capillary refill.
Treatment Protocol
Initial management includes RICE protocol (Rest, Ice, Compression, Elevation), protected weight-bearing with crutches, and knee immobilization in extension. Referral to physical therapy for quadriceps strengthening. Surgical consultation for potential PCL reconstruction given the complete nature of the rupture.
