Objective To explore the technique of arthroscopic treatment of synovial chondromatosis of the hip and to evaluate its effectiveness. Methods Between July 2009 and June 2011, 15 patients with synovial chondromatosis of the hip underwent arthroscopic synovectomy and removal of loose bodier. Of 15 patients, 11 were male and 4 were female, aged from 21 to 45 years with an average of 33.1 years. The location was the left side in 6 cases and the right side in 9 cases. The disease duration was 12-43 months (mean, 23 months) Pain and functional motion limitation were the main clinical symptoms. The visual analogue scale (VAS) score was 5.8 ± 1.1; the range of motion (ROM) of the hip was (149.8 ± 27.5)°; the Harris hip score was 54.5 ± 13.3. Results All incisions healed by first intention. All the patients were followed up 6 months to 2 years (mean, 17.4 months). At last follow-up, the VAS score was 2.0 ± 1.2; the ROM of the hip was (258.3 ± 35.4)°; the Harris hip score was 93.0 ± 18.7; and the above indexes were significantly improved when compared with preoperative values (P lt; 0.05). No recurrence was found on postoperative MRI. Conclusion Arthroscopic treatment of synovial chondromatosis of the hip has the advantages of minimal invasion, quick recovery, and best recovery of hip function and ROM.
【摘要】 目的 探讨关节镜治疗膝关节滑膜软骨瘤病的疗效。 方法 2005年1月—2009年10月，对23例（28膝）滑膜软骨瘤病患者入院行X线片、关节活动度检查、视觉模拟评分以及Lysholm膝关节功能评分。根据镜下所见分为表浅型6例，游离体型17例。结合病理学检查行Milgram 分期，Ⅱ期16例，Ⅲ期7例。所有患者均行关节镜下病变滑膜切除及游离体取出治疗。 结果 所有患者均随访13~57个月，平均（32.3±6.7）个月，术后伤口均甲级愈合。术后（5.05±2.43） d恢复正常生活或工作。症状明显改善21例（91.30%），部分改善2例（8.70%），对疗效满意23例（100%）。膝关节关节活动度由术前的伸膝（14.29±16.34）°以及屈膝（106.07±35.83）°提高到术后的伸膝（1.79±2.79）°及屈膝（132.64±35.64）°，差异具有统计学意义（Plt;0.05）。负重行走时疼痛视觉模拟评分由术前的（3.81±2.02）分降低到术后的（0.37±0.65）分（Plt;0.05）。Lysholm评分由术前的（43.20±8.24）分升至术后6个月的（86.72±5.40）分（Plt;0.05）；术后1年复诊并检查膝关节正侧位X线片，均未见滑膜软骨瘤体，所有患者无复发。 结论 关节镜下游离体取出术联合病变滑膜切除术疗效满意，关节疼痛明显减轻，功能恢复，是一种治疗膝关节滑膜软骨瘤病确切有效的方法。【Abstract】 Objective To investigate the therapeutic effect of arthroscopic treatment on synovial chondromatosis. Methods A total of 23 patients (28 knees) with synovial chondromatosis were diagnosed and treated in our hospital from January 2005 to October 2009. All of the patients underwent radiographic imaging examination, knee joint range of motion (ROM), visual analogue scale (VAS) and Lysholm score. According to distinct arthroscopic appearance, superficial pattern was found in 6 patients and loose body lesion pattern was in 17. Additionally, combined with pathological examination, according to the Milgram staging，Stage Ⅱ was in 6 patients and Stage Ⅲ was in 7. Arthroscopic limited synovectomy and removal of loose bodies were performed on all the patients. Results The patients were followed up for 13-57 months with the mean of (32.3±6.7) months. The wound of all patients healed up. The time of returning to normal work and life was (5.05±2.43) days for average. The postoperative symptom was markedly alleviated in 21 patietns and partly alleviated in 2. All patients were satisfied with the therapeutic effect. The mean activity of knee joint was significantly different befoe and after the surgery (Plt;0.05) preoperative extension and flexion degrees were (14.29±16.34) and (106.07±35.83) degrees, respectively; postoperative extension and flexion degrees were (1.79±2.79) and (132.64±35.64) degrees (flexion) , respectively. The mean VAS score of weight bearing walking was 0.37±0.65 after theoperation and 3.81±2.02 before the peration; the difference was significantly different (Plt;0.05). The preoperative Lysholm knee score was 34-67 with the mean of 43.20±8.24, and the post-operative score was 71-99 with the mean of 86.72±5.40. There were differences in preoperative and post-operative scores (Plt;0.05) . Radiographic imaging examination of knee joint was performed 1 year after the opertation, no loose bodies was seen and no patients recurred. Conclusion The therapeutic effect of arthroscopic limited synovectomy and removal of loose bodies is good on synovial chondromatosis.
Objective To evaluate the effectiveness of arthroscopy for synovial chondromatosis of hip joint. Methods Between April 2012 and September 2015, 32 patients with synovial chondromatosis of hip joint were treated by arthroscopy. There were 19 males and 13 females, with an average age of 42.1 years (range, 22-64 years). The synovial chondromatosis located at right hip in 15 cases and left hip in 17 cases. The main clinical symptoms were pain and swelling of hip joint. Of all patients, 6 cases were hip hinge, 2 cases were lower limb weakness, and 1 case was snapping hip. The " 4” sign was positive in 9 cases, Thomas’ sign positive in 4 cases, and rolling test positive in 2 cases. Results All incisions healed by first intention, and no complication occurred. All patients were followed up 16-48 months (mean, 33.8 months). The visual analogue scale (VAS) was 1.4±0.8 at last follow-up, which was significantly lower than that before operation (4.8±1.2) (t=6.382, P=0.013). The hip Harris score was 92.6±6.7 at last follow-up, which was significantly higher than that before operation (63.2±8.3) (t=9.761, P=0.006). At last follow-up, the " 4” sign and Thomas’ sign were positive in 3 cases and 1 case, respectively. The others had no positive sign. X-ray film showed no recrudescence in all cases. Conclusion Treating synovial chondromatosis of hip joint under arthroscopy has advantages of less trauma, complete debridement, quick postoperative recovery, and the satisfactory short-term effectiveness.
