Arthroscopic iliopsoas tenotomy after total hip arthroplasty: safe method for the right patient

Abstract

Abstract Purpose To evaluate the outcome of arthroscopic treatment for iliopsoas impingement after total hip arthroplasty (THA) 2 years after surgery using patient reported outcomes (PROM). Methods In this study 12 patients (13 hips) were included from a local hip arthroscopy registry. Patients completed web‐based PROMs preoperatively and at a minimum of 2 years postoperatively. The PROMs included the International Hip Outcome Tool short version (iHOT‐12), the Copenhagen Hip and Groin Outcome Score (HAGOS), the European Quality of Life‐5 Dimensions Questionnaire (EQ‐5D), the Hip Sports Activity Scale (HSAS) for physical activity level, the Visual Analog Scale (VAS) for overall hip function and a single question regarding overall satisfaction with the surgery. Results The mean age was 64.4 years (±15.1SD), mean body mass index (BMI) was 26.6 (±4.3SD), mean follow‐up time was 49.8 months (±25SD). Comparing PROMs preoperatively with 2‐year follow up showed an improvement for many of the PROMs used. The PROMs scores were iHOT‐12 (24.9 vs 34.5, p = 0.13), HAGOS subscales (symptoms 38.2 vs 54.5, p = 0.05; pain 36 vs 53, p = 0.04; sport 14.1 vs 35.1, p = 0.03; daily activity 31 vs 47.5, p = 0.04; physical activity 21.8 vs 24, p = 0.76; quality of life 24 vs 35, p = 0.03), EQ‐VAS (57.9 vs 58, p = 0.08), EQ‐5D (0.34 vs 0.13, p = 0.07) and VAS for overall hip function (43.1 vs 46.2, p = 0.14). In total, 10 out of the 12 patients (83%) were satisfied with the intervention. Conclusion Patients undergoing surgery for iliopsoas impingement after previous THA showed improved self‐reported hip function where most patients were satisfied with treatment.
