    Abstract:
    BACKGROUND: Neither operative nor nonoperative treatment of posterior cruciate ligament rupture after multiligament knee injuries have shown very favorable outcomes. HYPOTHESIS: Reconstruction of the posterior cruciate ligament by combining the tibial-inlay and two-femoral-tunnel techniques will result in improved stability and functional outcomes. STUDY DESIGN: Prospective cohort study. METHODS: Twenty-nine patients with 30 posterior cruciate ligament ruptures and multiligament knee injuries treated with the combined technique were evaluated with clinical, radiographic, and functional outcome measures. RESULTS: All patients had a clinical examination result indicating joint stability (0 or 1+) at an average follow-up of 25 months (range, 15 to 39). Twenty-three knees had no laxity, and seven had 1+ laxity. The KT-2000 arthrometer data documented less than 0.5 mm of side-to-side mean difference for both posterior displacement and total anterior-posterior displacement at both 30 degrees and 70 degrees of knee flexion. Knee range of motion was a mean extension of 1 degrees (range, 0 degrees to 10 degrees ) and a mean flexion of 124 degrees (range, 75 degrees to 145 degrees ). Mean Lysholm knee score was 89.4. CONCLUSIONS: Reconstruction with a combination tibial-inlay and two-femoral-tunnel technique provides good results after multiligament knee injuries. All patients had a stable posterior cruciate ligament at most recent clinical follow-up, and 77% had no laxity at all.
