Abstract
Purpose
The purpose of this study was to describe the long-term (> 5 year) clinical results of a novel arthroscopic fixation technique for osteochondral lesions of the talus (OLT), named the Lift, Drill, Fill and Fix (LDFF) technique.
Methods and Materials
19 ankles (21 patients) underwent an arthroscopic LDFF procedure for a primary OLT. The mean follow-up was 6.9 years (range: 71.4 - 90.8 months). Pre- and postoperative clinical assessment was prospectively performed by measuring the Numeric Rating Scale (NRS) of pain at rest, during walking and when running. Additionally, the Foot and Ankle Outcome Score (FAOS) including its sub-scores of pain, symptoms, activities of daily living, sports and quality.
Results
The median NRS during weightbearing significantly improved from 7 (IQR: 5 - 8) pre-operatively to 0 (IQR: 0 - 2) post-operatively (p = <0.001), and remained stable from 1-year postoperatively, see Figure 1. The NRS during running significantly improved from 8 (IQR: 6 - 10) to 2 (IQR: 0 - 5) (p < 0.001) and the NRS in rest from 2.5 (IQR: 1 - 3) to 0 (IQR: 0 - 0) (p = <0.001). The median FAOS at final follow-up was 94.4 out of 100 for pain, 71.4 for other symptoms, 98.5 for activities of daily living, 80 for sport and 56.3 for quality of life. The FOAS improved significantly post-operatively on all subscales, expect for the symptoms subscale.
Conclusion
Arthroscopic LDFF of a fixable primary OLTs results in excellent pain reduction and improvement of functional outcomes, with sustained results at long-term follow-up. These results indicate surgeons should consider fixation for a fixable OLT.
