Forty patients with anterior cruciate reconstructions using semitendinosus and gracilis autografts and a ligament augmentation device were reviewed at a minimum of 20 months postoperatively to determine if an accelerated rehabilitation program was detrimental to intermediate follow-up results. The rehabilitation program included immediate full weightbearing, using crutches as aids for 2 weeks only, and a Generation II rehabilitation brace set at full range of motion for 2 weeks followed at 2 weeks by bicycle riding and strengthening exercises. Return to sports was allowed at 4 months for nonpivoting sports and at 6 months for level 1 sports involving pivoting. Thirty-seven patients were available for followup. At followup, three grafts were determined to be nonfunctional (KT-1000 arthrometer testing indicating > 4 mm of side-to-side difference). The other 34 patients had good or excellent results, with all returning to their preinjury levels of sport with a brace. Early accelerated rehabilitation after anterior cruciate ligament reconstruction with semitendinosus and gracilis tendon autograft and a ligament augmentation device does not seem to affect the results adversely. Results in this series were as good as or better than other series using the same reconstructive technique.
