Abstract
Ankle arthrodesis is considered to be the gold standard treatment for a painful degenerated ankle not responding to conservative treatment. Its goals are to eliminate pain and deformity of the degenerated ankle joint and obtain a plantigrade foot for painless mobilization.
Arthrodesis techniques can be broadly classified into two categories: arthrodesis in situ (by mini-arthrotomy or arthroscopic assisted) and open (realignment) arthrodesis. Various surgical approaches and fixation methods may be considered depending on the status of the soft tissues, degree of deformity, bone quality, and experience of the surgeon.
This study included 30 patients of posttraumatic arthritis who were divided into two groups (15 patients each), group I was arthroscopic assisted technique and the other was mini-open technique using single anteromedial incision. Seven (47%) in group I and eight (53%) in group II were males. The mean age of the patients in group one was 41.3 ± 11.1 years and 35.7 ± 9.8 in group two. The Right side was affected in eight patients (53%) in group one and nine patients (60 %) in group two.
The mean pre-operative AOFAS score was poor, 49.5 ± 3.7 in group I and 43.4 ± 6.0 in group II. The mean post-operative score was good, 79.0 ± 9.2 in group I and 77.5 ± 10.1 in group II. At on-year –follow up and according to the AOFAS score, satisfactory results (excellent and good final outcomes) were found in 12 patients (80%) in group I and 11 patients (73.4%) in group II. On the other hand three patients (20%) in group I and four patients (26.6%) in group II had unsatisfactory results (fair final outcome). There was a statistical significant relationship between post-operative AOFAS score and union with better score in cases with solid fusion ( a mean of 81.9 ± 6.4) compared to cases with delayed or non-union (63.3 ± 2.3).
Post-operative coronal alignment was restored to normal in all cases with a mean 90.1 ± 1.2 degrees in group I and 89.9 ±1.2 degrees in group II with a pre-operative measured 89.3 ± 2.7 degrees in group I versus 87.8 ± 3.4 degrees in group II. The mean post-operative sagittal alignment was 98.9 ± 2.9 degrees in group I and 100.2 ± 2.7 degrees in group II with a pre-operative measured 102.3 ± 4.8 in group I versus 106.4 ± 5.9 in group II.
