To determine the outcome of total knee replacement using a posterior cruciate-substituting knee prosthesis in patients who have undergone previous patellectomy.
A cohort study, with a follow-up ranging from 2 to 9 years.
A university-affiliated institution specializing in elective orthopedic surgery.
Sixteen patients with arthritis of the knee who had had patellectomy. All agreed preoperatively to a prolonged postoperative follow-up.
A cemented posterior cruciate-substituting knee replacement.
Stair climbing ability, the Hospital for Special Surgery knee rating system for clinical results and a radiologic rating using a zonal system.
Clinical rating was 69% good or excellent. Eighty-one percent of patients could use the replaced knee as the lead leg on stair climbing. Minor radiolucency, mostly single zone only, was found. Two patients required revision because of pain, but no obvious reasons for this pain were found at operation.
In the absence of a patella, a posterior cruciate-substituting prosthesis gives reasonable results.
确定在既往接受过髌骨切除术的患者中使用后交叉韧带替代型膝关节假体进行全膝关节置换的结果。
一项队列研究，随访时间为2至9年。
一所大学附属的专门从事择期整形外科手术的机构。
16例患有膝关节关节炎且接受过髌骨切除术的患者。所有患者术前均同意进行长期的术后随访。
使用骨水泥固定的后交叉韧带替代型膝关节置换术。
爬楼梯能力、用于评估临床结果的特种外科医院膝关节评分系统以及使用分区系统进行的放射学评分。
临床评分为69%为良好或优秀。81%的患者在爬楼梯时能够将置换后的膝关节作为主导腿。发现有轻微的射线可透过性，大多仅为单个区域。两名患者因疼痛需要翻修，但手术中未发现导致这种疼痛的明显原因。
在没有髌骨的情况下，后交叉韧带替代型假体可取得合理的结果。
