Abstract

Introduction

Derby technique for posterolateral corner (PLC) reconstruction uses a doubled gracilis autograft to reconstruct the popliteo-fibular ligament (PFL) and a split biceps tendon transfer to reconstruct the lateral collateral ligament (LCL). We report midterm outcomes of a case series who underwent PLC reconstruction.

Methodology

A retrospective review of 27 patients who underwent PLC reconstruction from 2012 until 2018 was performed (6 females, 21 males, median age 26). Median time interval from injury to primary procedure was 10 months. Outcomes were recorded as per clinical assessment and outcome scores.

Results

All patients had no varus laxity in full knee extension. Similarly, at 30° of knee flexion, 25 patients (92.5%) had no varus laxity and 2 patients (7.5%) had grade 1 laxity. No patients demonstrated abnormal external rotation at final follow up. Outcome scores were obtained from 17 patients who underwent primary ligament reconstruction at a mean follow up of 72 months postoperatively. The mean Lysholm score was 94 +/-5.5 (72–100) and mean subjective IKDC score was 78/87 (89.6%) (51–87). 90% of our patients had gained normal or nearly normal IKDC scores on returning to routine activities of daily living and sports following surgery compared to their pre-injury status.

Conclusion

Our technique enables an anatomical LCL & PFL reconstruction in isolation or in combination with ACL/PCL reconstruction or to augment an acute repair without contralateral graft harvest or allograft. The functional knee scores demonstrated in this cohort are comparable and in fact superior to previously published knee scores after PLC reconstruction.
