Summary

Combined with posterior cruciate ligament reconstruction, the arthroscipic anatomical posterolateral corner reconstruction of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar outcomes, both techniques were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.

Abstract

Objective

The purpose of this study was to describe the clinical results of a one-stage operation for posterior cruciate ligament reconstruction and a posterolateral corner reconstruction of popliteus tendon reconstruction, compared with an open popliteofibular ligament reconstruction.

Methods

Our study included 33 patients who had undergone posterior cruciate ligament reconstruction with use of an Achilles tendon-bone allograft and posterolateral corner reconstruction with arthroscopic anatomical reconstruction of popliteus tendon or open reconstruction of popliteofibular ligament. Patients were assessed for knee instability with use of the dial test at 30° and 90°, together with posterior stress radiography and KT-1000 measurement.

Results

The mean time of follow-up was more than 2 years. At the final follow-up evaluation, the tibial posterior translation as measured by stress radiography at 90° of knee flexion, the anterior-posterior translation as measured by KT-1000, and the external rotation of tibia as measured by dial test was reduced postoperatively (p=0.000) in both groups. Between the two groups, the preoperative tibial posterior translation as measured by stress radiography and the preoperative mean anterior-posterior translation as measured by KT-1000 in the popliteofibular ligament group was a little more than the popliteus tendon group (p=0.014, p=0.000). But the other comparisons were not significant differences (p>0.05). The final flexion loss were 3.33° ± 4.88° and 3.06°± 3.38° for two groups.

Conclusions

Combined with posterior cruciate ligament reconstruction, anatomical posterolateral corner reconstruction of the popliteus tendon and open reconstruction of popliteofibular ligament showed similar outcomes. This study demonstrated that both posterolateral corner reconstruction technique were a reliable alternative method in addressing posterolateral corner and posterior cruciate ligament insufficiency of the knee.
