Abstract
BACKGROUND: Although metatarsophalangeal (MTP) arthrodesis has been advocated by many authors, implant arthroplasty appears to be successful option in advanced hallux rigidus (HR). The aim of our study was to evaluate the early results of the ToeFit-Plus prosthesis for the treatment of HR.
METHODS: Between December 2007 and January 2011, a total of 26 toes of 24 patients with MTP arthritis of the great toe were treated with ToeFit-Plus implant. The average follow-up time was 29.9 (range: 25 to 62) months. All patients were evaluated clinically and radiographically. Postoperative satisfaction and function were scored according to the American Orthopaedic Foot and Ankle Society (AOFAS) score. Pain was assessed with the use of a visual analogue scale.
RESULTS: Mean preoperative AOFAS score improved from 42.7 (range: 36 to 59) to 88.5 (range: 59 to 98) at the final follow-up (P < .01). Preoperative average visual analogue scale pain scores improved from 7.4 preoperatively to 1.9 at the final follow-up (P < .01). The average MTP joint range of motion improved from 25.9 degrees preoperatively to 53.8 degrees at the final follow-up. No radiologic loosening was found, but radiolucency was observed in 2 patients with this implant. No revision was required for any of the patients during the follow-up period.
CONCLUSIONS: This total first MTP joint prosthesis yielded good functional outcome and high patient satisfaction level with low early complication rate. Preservation of joint movement and good pain relief with early mobilization were the advantages of this procedure. Salvage arthrodesis remains an option if future revisions are indicated.
LEVEL OF EVIDENCE: Level IV, retrospective case series.
