Clinical outcomes pertaining to isolated lateral fabellectomy in the setting of fabella syndrome are limited to small case reports at this time.
To assess the most common presenting symptoms, clinical outcomes, and satisfaction after fabella excision in the setting of fabella syndrome.
Case series; Level of evidence, 4.
Consecutive patients with a minimum of 21-month follow-up after isolated fabellectomy for fabella syndrome were reviewed retrospectively. Clinical outcome scores of the following domains were collected: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and Lysholm knee survey, along with a simple numeric patient satisfaction score (range, 1-10; 10 = "very satisfied"). Statistical analysis was performed using paired tests for all clinical outcome data.
A total of 11 isolated fabella excisions were included in 10 patients with isolated lateral-sided knee pain in the setting of fabella syndrome (8 males, 2 females), with a mean age of 36.9 years (range, 23-58 years) and a mean follow-up of 2.4 years (range, 21-47 months). A total of 8 patients (80%) were able to return to full desired activities, including sports. Only 5 of 11 (45%) excisions had concomitant lateral femoral condyle cartilage pathology. There were significant improvements across multiple WOMAC domains, and the WOMAC total score improved from 28.5 ± 17.6 preoperatively to 11.6 ± 10.2 postoperatively ( < .05). Lysholm scores significantly improved from 66.6 ± 23.1 preoperatively to 80.2 ± 13.9 postoperatively ( = .044). Overall patient-reported satisfaction was 8.8 ± 1.6.
Fabella excision in the setting of fabella syndrome demonstrated improvements in clinical outcome scores, high rate of returning to preinjury level of activities, and low risk of complications or need for additional surgical procedures.
目前，关于在籽骨综合征背景下进行单纯外侧籽骨切除术的临床结果仅限于小型病例报告。
评估籽骨综合征患者籽骨切除术后最常见的症状表现、临床结果及满意度。
病例系列研究；证据等级为4级。
对因籽骨综合征接受单纯籽骨切除术后至少随访21个月的连续患者进行回顾性分析。收集以下领域的临床结果评分：西安大略和麦克马斯特大学骨关节炎指数（WOMAC）评分及Lysholm膝关节量表，以及简单的数字患者满意度评分（范围为1至10；10表示“非常满意”）。对所有临床结果数据采用配对检验进行统计分析。
10例因籽骨综合征出现单纯膝关节外侧疼痛的患者共进行了11次单纯籽骨切除术（8例男性，2例女性），平均年龄36.9岁（范围为23至58岁），平均随访2.4年（范围为21至47个月）。共有8例患者（80%）能够恢复到期望的全部活动，包括运动。11例切除术中只有5例（45%）伴有外侧股骨髁软骨病变。多个WOMAC领域均有显著改善，WOMAC总分从术前的28.5±17.6提高到术后的11.6±10.2（P<.05）。Lysholm评分从术前的66.6±23.1显著提高到术后的80.2±13.9（P = .044）。患者总体报告的满意度为8.8±1.6。
籽骨综合征患者进行籽骨切除术后，临床结果评分有所改善，恢复到伤前活动水平的比例较高，并发症风险或额外手术需求较低。
