In early stages of osteoarthritis, osteotomy produced a satisfactory result with no adverse effects and significant improvement in the nonoperated-on contralateral hip. In many cases of unilateral osteotomy in a group with preoperative radiologic scores above 70, the function was either improved or unchanged in the nonoperated-on hip. In many cases with scores below 70, there was deterioration of joint structure. Bilateral osteotomy is recommended only in the cases with preoperative radiologic scores below 70. Osteotomy was prescribed on the contralateral hip within a short period of time after aarthroplasty. Deterioration occurred in some contralateral nonoperated-on hips when the preoperative clinical scores were high, while improvement generally occurred when preoperative scores were low.
在骨关节炎早期，截骨术产生了令人满意的结果，没有不良反应，且未手术的对侧髋关节有显著改善。在术前放射学评分高于70分的一组患者中，许多单侧截骨病例中，未手术髋关节的功能要么改善，要么未改变。在许多评分低于70分的病例中，关节结构出现恶化。仅在术前放射学评分低于70分的病例中建议进行双侧截骨术。在关节置换术后短时间内在对侧髋关节进行截骨术。当术前临床评分较高时，一些对侧未手术髋关节出现恶化，而术前评分较低时通常出现改善。
