目的探讨小切口摘除膝关节游离体的治疗方法和疗效。
Objective To investigate the method and effect of removal of intraarticular free body of knee through small incision.
结果术前高频超声提示正确率为81。 6% （31 /38），其中包括半月板损伤18例、关节内游离体7例及滑膜病变6例。
Results The diagnostic accuracy of high frequency ultrasound was 81.6% (31/38), including 18 cases of meniscal tear, 7 cases of loose body and 6 cases of synovial lesions.
CT可区分高密度影是关节腔游离体还是软组织内钙化或关节囊钙化。
CT can differentiate freebodys in the joint cavity with the calcification of the soft tissue or joint sac.
方法关节镜下手术，清理关节内游离体及病变滑膜。
Methods Multiple loose bodies and degenerative synovia were removed under knee arthroscopy.
结论双切口入路在治疗单纯半月板损伤、膝关节内游离体或滑膜皱襞综合征的关节镜手术中同样可以达到满意的诊断和治疗目的。
Conclusions The double operative approaches in arthroscopy treating of meniscus injuries or knee joint loose bodies or mediopatellar plica syndrome have good curative effect.
