ObjectiveThe purpose of this case report is to describe the evaluation and conservative management of an isolated posterior cruciate ligament (PCL) tear.Clinical FeaturesA 32-year-old man with a traumatic right knee injury after tripping was initially diagnosed with medial patellar retinaculum tear at a multidisciplinary clinic. The patient received physiotherapy but reinjured the knee after returning to the sports field 3 weeks later. Subsequent clinical testing and magnetic resonance imaging confirmed a grade II isolated PCL tear.Intervention and OutcomeFollowing the PCL tear diagnosis, a multimodal treatment approach over the course of 8 weeks consisting of chiropractic lumbopelvic manipulation, physiotherapy, and an exercise program emphasizing eccentric muscle action was implemented. Lunges, 1-leg squats, and trunk stabilization exercises were extensively used. Three months postinjury, the patient successfully returned to sports activity with no further complications.ConclusionThe patient in this case report demonstrated successful return to preinjury functional status. This case highlights a multidisciplinary approach through the utilization of chiropractic, physiotherapy, and exercise therapies.
