Treatment for a PCL Sprain

The posterior cruciate ligament helps limit backward movement of the shin bone relative to the thigh bone. A sprain may stretch the ligament or tear some or all of its fibres. It can happen when the front of the knee strikes an object, the knee bends forcefully, or a sports injury occurs. Pain, swelling, reduced confidence on stairs, and a feeling of instability can occur. A clinician examines the knee and may use imaging to assess the ligament and associated injuries.

Reduce activities that cause pain, swelling, or buckling. Early care may include elevation, a wrapped cold pack for comfort, and a brace or crutches when prescribed. Follow the weight-bearing instructions you were given; do not test the knee with running, jumping, or twisting. Physiotherapy can restore motion and build control in the quadriceps, hip, and whole leg while protecting the healing ligament. Kinesiology taping may be used as an adjunct by a trained professional, but it does not replace assessment or rehabilitation. More severe or combined injuries may require an orthopaedic discussion about reconstruction.

Arrange assessment after a knee injury if swelling, pain, or instability limits walking. Seek prompt care for a locked knee, inability to bear weight, marked deformity, or swelling that develops quickly. Emergency assessment is needed for a cold or pale foot, new numbness, severe calf swelling, or rapidly increasing pain. Contact your clinician if the brace causes skin injury or if the knee repeatedly gives way during the recovery plan.

Is the PCL stretched or torn, and are other knee structures injured? Do I need a brace or crutches, and for how long? Which exercises and weight-bearing limits apply? When can I cycle, run, or return to sport? What findings would make surgery worth discussing?
