Purpose
The purpose of this study was to document subjective outcomes following anatomic-based reconstruction of the popliteus tendon when the popliteus tendon was the only injured posterolateral knee structure. It was hypothesized that popliteus tendon reconstruction would result in improved patient outcomes after surgery regardless of the concurrent ligamentous or intra articular pathology.
Methods
A consecutive series of 5 patients with a median age of 23 years (range, 22–36 years) who underwent anatomic popliteus tendon reconstruction along with concomitant ligament reconstruction or meniscus repair (if needed) were included in this study. All patients completed pre-operative and post-operative subjective questionnaires, which included the Lysholm score to document function, the Tegner activity scale to document activity level, and a patient satisfaction with outcome question.
Results
All patients were available for a final follow-up at a median time of 2.8 years (range, 2–3.9 years) following the index surgery. Three patients had a combined popliteus tendon and posterior cruciate ligament reconstruction. Two of the three PCL reconstructions were revision procedures. The Lysholm score improved to from 53 (range, 34–90) to 91 (range, 44–100) at post-operative follow-up. The median pre-operative Tegner activity scale improved from 3 (range, 0–9) to a median score of 4.8 (range, 2–7) at post-operative follow-up. The median patient satisfaction with outcome was 9 (range, 7–10). The dial test at 30° and 90° improved in all patients following surgery.
Conclusions
Anatomic-based popliteus tendon reconstructions resulted in improved outcomes and a high patient satisfaction in patients with a complete tear of the popliteus tendon and symptomatic knee instability.
