Abstract

BACKGROUND:

Arthroscopic arthrodesis has been used mainly for in situ fusion of arthritic ankles without deformity. This paper presents the application of arthroscopic arthrodesis of ankles with marked deformity.

METHODS:

The results of 78 consecutive cases of arthroscopic ankle arthrodeses, performed in 74 patients, were retrospectively evaluated. Forty-eight ankles had minor deformity (group A), whereas 30 ankles had a varus or valgus deformity of more than 15 degrees (maximum 45 degrees) (group B). The average hospital stay was 3.8 and 3.4 days in groups A and B, respectively (p = 0.74). Postoperative treatment included ankle immobilization for 3 months. Progressive weightbearing was initiated at 2 weeks. Mean followup was 21.1 months.

RESULTS:

Fusion occurred in 47 of 48 (97.9%) ankles in group A at an average time of 13.1 +/- 5.8 weeks and in 29 of 30 (96.7%) ankles at 11.6 +/- 2.4 weeks in group B (p = 0.19). Unplanned operative procedures were required in 11 ankles (14.1%). One superficial wound infection occurred. Symptomatic arthritis from the adjacent joints developed in six ankles (7.7%). Postoperative ankle alignment in the frontal plane averaged 0.7 and 0.4 degrees of valgus (p = 0.41), whereas the sagittal plane angle averaged 106 +/- 4 degrees and 104.5 +/- 7 degrees in groups A and B, respectively (p = 0.22). The outcome was graded as very good in 79.2% (38 feet) in group A and 80% (24 feet) in group B, fair in 18.8% (9 feet) in group A and 16.7% (5 feet) in group B and poor in one ankle in each group (p = 0.68).

CONCLUSIONS:

The arthroscopic technique offered high fusion rates and low morbidity. Deformity correction was achieved with good results.
