Role of Arthroscopic Debridement of Hemophilic Ankles.

BACKGROUND

Arthroscopic debridement has been used in the treatment of early stages of hemophilic ankle arthropathy. The aim of this procedure is to alleviate pain, improve function, and diminish bleeding episodes. Evaluation of patient-reported outcomes of arthroscopic debridement for hemophilic ankle arthropathies was evaluated in this study.

METHODS

Fifteen patients with hemophilia who had undergone arthroscopic debridement between 2008 and 2017 were included in this study. Preoperative American Orthopaedic Foot & Ankle Society Score (AOFAS) and Foot Function Index (FFI) with its subscales were obtained. Patient-reported outcome was measured using FFI at the latest follow-up. Radiologic severity of hemophilic arthropathy was assessed with the Pettersson score. Preoperative and postoperative intraarticular bleeding frequencies of the hemophilic patients were compared.

RESULTS

Patients experienced statistically significant improvements of FFI and its subscales. Median preoperative FFI scores dropped from 42.2% to 22.2% postoperatively. Median value for the Pettersson score was 3. Annual median bleeding frequency of the study group was 18 preoperatively and 1.5 postoperatively ( P = .002).

CONCLUSION

By assessing patient-reported outcomes, pain and functional restrictions associated with hemophilic ankle arthropathy were improved following arthroscopic debridement. By means of subjective measures, this procedure was effective.
