Clinical Presentation & Protocol
Patient Usually Complains Of
Patient presents with acute onset of left knee pain and instability following a high-energy trauma involving a direct blow to the proximal tibia with the knee in a flexed position. Patient reports a sensation of "giving way," significant posterior knee pain, and difficulty with weight-bearing. No neurovascular deficits noted.
Clinical Examination Findings
Left knee examination reveals significant posterior sag sign of the proximal tibia relative to the femur. Posterior drawer test is positive (Grade III, >10mm) with a soft endpoint. Lachman and anterior drawer tests are negative. Varus/valgus stress testing is stable. Neurovascular status is intact with palpable distal pulses and normal sensation.
Treatment Protocol
Immediate management includes immobilization with a hinged knee brace in full extension, RICE protocol (Rest, Ice, Compression, Elevation), and non-weight bearing status with crutches. Referral to orthopedic surgery for definitive management of complete PCL rupture. Analgesia prescribed for pain control.
