Abstract |
Periacetabular osteotomy (PAO) is an effective procedure in treatment of symptomatic hip dysplasia. To achieve a good outcome a strict patient selection has to be applied. The aim of this study was to evaluate the influence of patient age at surgery on clinical outcome. In a prospective study 86 patients (106 hips) underwent clinical and radiographic follow-up at a mean time of 5 years (2.5-8.5 years) after PAO. Patient-related outcome measurements (PROMs: EQ-5D, WOMAC, OHS, GTO) were applied preoperatively as well as postoperatively and the deformity correction as well as development of osteoarthritis were evaluated. In order to analyze the influence of patient age at surgery on clinical outcome, we subdivided the patient cohort into four different age groups (<20 years, 20-29 years, 30-39 years, >40 years). Of the patients 90% were very satisfied or satisfied with the results 5 years after surgery, and in all age groups PROMs significantly increased. Even though preoperative as well as postoperative algofunction declined in cohorts with increasing age, the overall benefit as measured in WOMAC and EQ-5D scores was equal in all age groups. Increasing age is associated with a progression in osteoarthritis as well as a higher conversion rate to total arthroplasty. Age is an important influencing factor on the long-term outcome after PAO. A certain age as cut off for indications could not be identified in this study. Even patients in the age groups 30-39 years and > 40 years showed PROM improvement and satisfaction with outcome at medium-term follow-up. The expected success rate has to be discussed preoperatively with the patient; however, as a higher conversion rate to hip arthroplasty as well as progressive osteoarthritis is associated with higher age, not only patient age alone but also morphological characteristics of the hip joint have to be taken into consideration. |
