Revision anterior cruciate ligament reconstruction with a reharvested ipsilateral patellar tendon.

The patellar tendon remains the most popular graft choice for anterior cruciate ligament reconstruction and has been proven to be the strongest substitute. Between 1991 and 1998, we performed revision anterior cruciate ligament reconstruction using the reharvested central third of the ipsilateral patellar tendon in 15 patients. Adequate follow-up was obtained in 13 of these 15 patients. The results in these 13 patients (mean age, 27.2 years) were reviewed. At an average postoperative follow-up of 39.4 months (range, 24 to 65), 11 patients had good or excellent results and 2 patients had fair results. Clinical examination revealed an average Tegner knee score of 5.8 (range, 3 to 9) and an average Lysholm knee score of 77.6 (range, 61 to 98). Postoperative KT-1000 arthrometer results showed an average side-to-side difference of 1.92 mm (range, -2.0 to 4.0). No patient demonstrated any loss of range of motion and only one reported patellofemoral problems, which were moderate. These favorable results demonstrate that, with appropriate patient selection, the use of a reharvested central third patellar tendon is a viable option for revision of a failed anterior cruciate ligament reconstruction.
