It has been reported that the unicompartmental knee arthroplasty has good long-term outcomes for Western and Japanese patients. Alternatively, several reports have described reoperations after unicompartmental knee arthroplasty because of post-operative knee pain and sometimes it is difficult to diagnose the cause of pain.
We treated a patient with anteromedial knee pain caused by intra-articular scar tissue that contained residual cement fragments on the anterior surface of a femoral implant following Oxford unicompartmental knee arthroplasty. After arthroscopic resection of the scar tissue and removal of the 3 mm residual cement covered with the scar tissue, the patient's post-operative symptoms were considerably alleviated.
This is the first report describing a case of painful intra-articular scar tissue following unicompartmental knee arthroplasty.
据报道，单髁膝关节置换术对西方和日本患者具有良好的长期疗效。另外，有几份报告描述了单髁膝关节置换术后因膝关节疼痛而进行的再次手术，有时很难诊断疼痛的原因。
我们治疗了一名患者，其膝关节前内侧疼痛是由关节内瘢痕组织引起的，该瘢痕组织包含牛津单髁膝关节置换术后股骨假体前表面残留的骨水泥碎片。在关节镜下切除瘢痕组织并去除覆盖在瘢痕组织上的3毫米残留骨水泥后，患者的术后症状得到了显著缓解。
这是第一份描述单髁膝关节置换术后关节内疼痛性瘢痕组织病例的报告。
