The purpose of this study was to compare the clinical results of arthroscopic tibial inlay single-bundle and double-bundle techniques with those of the conventional transtibial single-bundle technique.METHODS:  We evaluated twenty-nine patients treated with primary posterior cruciate ligament reconstruction and followed for longer than two years. Eight patients were treated with a transtibial single-bundle procedure; eleven, with an arthroscopic inlay single-bundle procedure; and ten, with an arthroscopic inlay double-bundle procedure. An Achilles tendon allograft was used in all cases. Each patient was evaluated on the basis of the Lysholm knee score, the mean side-to-side difference in tibial translation as measured on Telos stress radiographs, and the side-to-side difference in the range of motion of the knee.RESULTS:  The mean side-to-side difference (and standard deviation) in posterior tibial translation differed significantly between the arthroscopic tibial inlay double-bundle group (3.6 ± 1.43 mm) and the transtibial single-bundle group (5.6 ± 2.0 mm) (p = 0.023), although there was no significant difference between the arthroscopic inlay single-bundle group (4.7 ± 1.62 mm) and the transtibial group (p = 0.374). The mean range of motion and Lysholm scores were similar among the three groups.CONCLUSIONS:  Despite its technical difficulty, the arthroscopic tibial inlay double-bundle technique is our preferred method of reconstruction of the posterior cruciate ligament because it stabilizes posterior tibial translation better than do the other two methods.LEVEL OF EVIDENCE:  Therapeutic Level III.
