| Abstract: | BackgroundFirst metatarsophalangeal joint (MTPJ1) hemiarthroplasty using a novel synthetic cartilage implant was as effective and safe as MTPJ1 arthrodesis in a randomized clinical trial. We retrospectively evaluated operative time and recovery period for implant hemiarthroplasty (n = 152) and MTPJ1 arthrodesis (n = 50).MethodsPerioperative data were assessed for operative and anaesthesia times. Recovery and return to function were prospectively assessed with the Foot and Ankle Ability Measure (FAAM) Sports and Activities of Daily Living (ADL) subscales and SF-36 Physical Functioning (PF) subscore.ResultsMean operative time for hemiarthroplasty was 35 ± 12.3 min and 58 ± 21.5 min for arthrodesis (p < 0.001). Anaesthesia duration was 28 min shorter with hemiarthroplasty (p < 0.001). At weeks 2 and 6 postoperative, hemiarthroplasty patients demonstrated clinically and statistically significantly higher FAAM Sport, FAAM ADL, and SF-36 PF subscores versus arthrodesis patients.ConclusionMTPJ1 hemiarthroplasty with a synthetic cartilage implant took less operative time and resulted in faster recovery than arthrodesis.Level of evidenceIII, Retrospective case control study. |
