title: Quadriceps muscular strength after removal of the central third patellar tendon for contralateral anterior cruciate ligament reconstruction surgery: a case study.
abstract: Surgical reconstruction of the anterior cruciate ligament (ACL) using a patellar tendon autograft is a common orthopaedic procedure. Complications such as arthrofibrosis, patellar fracture, significant donor site pain, and quadriceps muscle weakness can occur from this procedure. Previous studies have not documented the effects of isolated graft procurement without concomitant ligamentous reconstruction on the donor extremity. This case study documents the clinical outcome results of an individual who underwent a central one-third graft harvest from his contralateral uninjured knee for an ACL graft of his injured ACL-deficient knee. The results indicate that at 4 months following graft procurement, the knee extensors were equal to the preoperative isokinetic test results of that leg. In addition, the patient exhibited full range of motion and no patellofemoral complaints of dysfunction. At 12 months postsurgery, the graft donor leg was 5-9% stronger than the preoperative test results. The results of this case study suggest that isolated harvesting of a 10-mm central patellar tendon free graft may not result in significant quadriceps muscle weakness or contribute to donor site pain.
