Abstract
BackgroundCurved periacetabular osteotomy (CPO) was developed to treat acetabular dysplasia. Given that CPO can improve physical function in the early post-operative period, patients might be able to participate in sports activities post-operatively. Therefore, this study examined the post-operative sports activity participation and characteristics of acetabular dysplasia patients who have undergone CPO.MethodsA total of 52 patients who underwent CPO for acetabular dysplasia were given a questionnaire on pre- and post-operative sports activities; 43 patients responded. We surveyed patients’ sports activities, satisfaction, and physical function. Patients were divided according to whether they participated in sports activities after CPO. Physical function was compared before and after CPO.ResultsThe pre- and post-operative sports activity participation rates were 55.8 and 72.1%, respectively. Patients mostly performed low-impact sports activities. Moreover, patients who participated in sports activities post-operatively had smaller pre-operative range of motion of hip flexion and returned to full weight bearing earlier.ConclusionsAmong acetabular dysplasia patients who underwent CPO, 72.1% participated in sports activities post-operatively. Post-operatively, patients participated not only in low-impact sports activities, but also in high-impact ones. These findings might be useful for advising patients who are concerned about participating in sports activities after CPO.
Highlights
Curved periacetabular osteotomy (CPO) was developed to treat acetabular dysplasia
Curved periacetabular osteotomy (CPO), a modified Periacetabular osteotomy (PAO) developed by Naito et al [10], is indicated for patients with mild or severe dysplastic hips [11]
At the time of the survey, OA progressed in 1 case, but there was no significant association with sports activity participation (P = 0.28); this patient did not participate in sports activities pre- or post-operatively
Summary
Curved periacetabular osteotomy (CPO) was developed to treat acetabular dysplasia. Given that CPO can improve physical function in the early post-operative period, patients might be able to participate in sports activities post-operatively. CPO provides pain relief and early improvement of hip abductor muscle strength because it preserves the hip abductor muscle, which reduces the dynamic instability of the hip joint during walking [12,13,14] Another advantage of CPO is its low risk of necrosis of the femoral head and acetabulum owing to the maintenance of blood supply to the rotated acetabulum and the small skin incision required [10]. These benefits of CPO reduce post-operative complications, promote early rehabilitation, and increase the likelihood of being able to participate in sports activities.
