비구 이형성증 환자의 관절 내 병변과 비구 회전절골술 중 비구순 손상 동반 치료의 유용성에 대한 고찰

다국어 초록 (Multilingual Abstract)

Purpose : The purpose of the study was to examine the intra-articular arthroscopic findings in the dysplastic hip and to clarify the efficacy of concomitant arthroscopic procedures for the intraarticular lesions with periacetabualr rotational osteotomy.
Materials and methods : We investigated 52 hips in 49 patients with symptomatic hip dysplasia without advanced degenerative osteoarthritis. We underwent arthroscopic examination during the periacetabular rotational osteotomy (PARO) to evaluate intraarticular lesion. Three kinds of procedures were performed for the labral lesion, observation (group A), debridement (group B), and repair (group C). The clinical findings, Harris hip score, impingement sign, were evaluated. Radiological measurements, center-edge angle, T?nnis osteoarthritis grade, were evaluated.
Results : Labral injury (tear and fibrillation) was found in 46 hips(88.6 %), and chondral lesion was found in 28 hips(53.8 %). Longitudinal tear was frequently observed in patients with T?nnis Gr 0, and degenerative tear in T?nnis Gr I. There were no clinical difference in final results in the group A, B and C. A deterioration in degenerative osteoarthritis were found in 2 hips with labral debridement treatment(group B).
Conclusion : The high incidence of labral lesions suggested that the pain onset of hip dysplasia is closely associated with a subsistent labral lesion. Abnormal joint stress and coexistance of subsequent intraarticular lesions contribute to clinical and radiological deterioration. If the abnormal concentration of joint stress is ameliorated by corrective osteotomy and followed by adequate joint stress distribution and joint stability, pain may be improved even when a labral lesion remained.
