For an isolated posterior cruciate ligament (PCL) injury, closed-chain quadriceps strengthening is the initial treatment of choice. While isolated PCL injuries are rare, multiple studies have reported successful outcomes (patient satisfaction and return to sport) with non-operative management. However, no clear prognostic factors predict outcomes and ideal management is unclear. By strengthening the quadriceps, the concept is to dynamically counteract the increased posterior tibial translation with a PCL-deficient knee. Similarly, rehabilitation of an ACL-deficient knee would consist of hamstring strengthening. When non-operative management fails, surgery may consist of single-bundle, double-bundle, trans-tibial, or tibial inlay reconstruction techniques. Parolie et al. looked at the long-term results of nonoperative treatment of isolated PCL injuries in athletes. They examined 25 patients with a mean follow-up of 6.2 years. At follow-up, they found that 84% of patients returned to sport without requiring surgery. Agolley et al. studied the return of athletes to sport following the nonoperative treatment of isolated PCL injuries. They prospectively studied 46 patients until return to sport-specific training and again at an average of 5.2 years from injury. They concluded that non-operative management of isolated PCL injuries (Hughston grade II and III) within four weeks of injury gives excellent functional outcomes with a high proportion of athletes returning to the same or higher level of sport. Figure A is an MRI of an ACL rupture. Figure B is an MRI of a PCL rupture. Figure C is an MRI of a patellar tendon rupture. Figure D is an MRI of a bucket-handle meniscal tear. Figure E is an MRI of a meniscal root tear. Illustration A shows the difference between closed and open chain exercises for quad strengthening. The foot is fixed in closed chain exercises. Incorrect Answers: Answer 1: ACL rehabilitation consists of hamstring strengthening exercises. Answers 3, 4, and 5: Surgical management is typically indicated for these conditions.
