Current role for radioisotope synovectomy

Radioisotope synovectomy has been extensively used to treat patients with chronic inflammatory joint disease but has moved to a less prominent position since the introduction of new and highly effective drugs. Remaining indications are refractory synovitis, pigmented villonodular synovitis as an adjunct to surgery, and hemophilic arthropathy. The three main radioisotopes used are yttrium-90, rhenium-186, and erbium-189. Radioisotope synovectomy should be performed only by highly experienced professionals, to minimize the risk of injection-related complications. The available safety data, in particular regarding the risk of malignancy, are reassuring. The efficacy of yttrium-90 in chronic inflammatory joint disease remains controversial.     

膝关节弥漫型色素沉着绒毛结节性滑膜炎的手术治疗

目的比较开放性滑膜切除术与关节镜下滑膜切除术治疗膝关节弥漫型色素沉着绒毛结节性滑膜炎(PVNS)的治疗效果。方法回顾性分析北京协和医院1994年3月至2013年10月手术治疗的有完整随访资料的膝关节弥漫型PVNS患者47例,所有患者根据手术方式分为开放性手术组和关节镜手术组,其中开放性手术组17例(接受开放性滑膜切除术)、关节镜手术组30例(接受关节镜下滑膜切除术),两组术后常规放疗。术后平均随访时间(15.7±16.3)个月(10~30个月),记录所有患者手术前及末次随访时的关节活动度、国际膝关节评分委员会(IKDC)评分和Lysholm评分以及两组患者复发率,比较两组患者治疗效果和复发率。结果随访期间共8例患者复发,复发率17.0%;其中开放性手术组3例复发,复发率17.6%;关节镜手术组5例复发,复发率16.7%;两组复发率比较差异无统计学意义。开放性手术组末次随访和术前的膝关节活动度、IKDC评分和Lysholm评分分别为(97.5±14.3)°和(69.7±12.6)°,(74.5±6.1)和(38.6±5.4)分,(77.5±5.8)和(42.4±4.6)分,关节镜手术组末次随访和术前的膝关节活动度、IKDC评分以及Lysholm评分分别为(128.6±13.9)°和(64.9±13.2)°,(87.4±6.7)和(37.2±4.9)分,(86.2±6.2)和(41.9±5.3)分,末次随访均较术前显著增加(P均<0.05),关节镜手术组末次随访的关节活动度、IKDC评分和Lysholm评分均较开放性手术组显著增加,差异有统计学意义(P均<0.05)。结论开放性滑膜切除术与关节镜下滑膜切除术治疗弥漫型PVNS的复发率相当,但后者膝关节活动度、膝关节功能评分显著高于前者,所以关节镜治疗膝关节弥漫型PVNS是一个较好的选择。     

No difference in health-related quality of life in hip osteoarthritis compared to degenerative lumbar instability at pre- and 1-year postoperatively: A prospective study of 101 patients

Background?Total hip replacement (THR) is a very successful and refined surgical procedure when compared to crude bony fusion in degenerative lumbar segmental instability (LF). We compared the pre- and postoperative health-related quality of life status of THR and LF patients.

Patients and methods?We prospectively studied 51 THR patients and 50 LF patients. The outcome parameters were SF-36 and Oswestry Disability Index (ODI), measured preoperatively and at 1 year postoperatively. The status of the patients was compared to that of an age-matched healthy control group.

Results?The preoperative SF-36 and ODI scores were similar between the groups, except for the subscale role emotional. One year postoperatively, only the differences in 3 subscales (physical functioning, role physical, and role emotional) and in the standardized physical component reached statistical significance; the THR-patients scored worse than the LF-patients. The improvements in SF-36 and ODI reached statistical significance in both groups.

Interpretation?The differences in quality of life between the THR and LF patients were similar pre- and postoperatively. The quality of life of both cohorts improved considerably and significantly after the treatment, but they remained at a level significantly below that of a general age-matched population.     

Isolated proximal tibiofibular joint arthritis in a patient with juvenile idiopathic arthritis: A case report

We report the case of a 14-year-old girl of juvenile idiopathic arthritis (JIA) with isolated and chronic proximal tibiofibular (PTF) joint arthritis. The clinical history, magnetic resonance imaging, and pathological findings of the patient are presented. We should be careful to evaluate the patient for chronic lateral knee pain, and consider concomitant evaluation for JIA, including rheumatoid arthritis.     

Efficacy of arthroscopic synovectomy for the effect attenuation cases of infliximab in rheumatoid arthritis

To investigate whether arthroscopic synovectomy is effective for nonresponders to infliximab, anti-tumor necrosis factor-α antibody, for the treatment of rheumatoid arthritis (RA), we assessed seven patients including ten arthroscopic synovectomies in knee joint, in shoulder joint, and in ankle joints. We compared C-reactive protein (CRP) and DAS28 (ESR) before and after surgery at 6 and 50 weeks. After arthroscopic synovectomy, we continued the infliximab treatment with methotrexate in a routine manner. We detected synovium proliferation with vascular increase in patellofemoral joint and around the meniscus and femoral and tibial side of the anterior cruciate ligament in the knee joints. We also found synovial proliferation in rotator interval in the glenohumeral joint and fatty changing in subacromial bursa in the shoulder. In the ankle joint, we found synovial proliferation with white meniscoid between tibiofibular joint to develop impingement. Serum CRP was improved from 3.45±0.4 to 1.12±0.2 at 6 weeks to 1.22±0.4 at 50 weeks after arthroscopic synovectomy. There is no severe side effect of arthroscopic synovectomy during infliximab treatment; however, one patient had slight rash that was improved. DAS28 was improved from 5.58±0.23 to 3.87±0.47 at 6 weeks to 2.58±1.49 at 50 weeks after arthroscopic synovectomy. It is possible that arthroscopic synovectomy can be one of the effective methods to continue with the infliximab treatment when its efficacy decreased or in the nonresponders of infliximab for RA patients.     

Arthroscopic synovectomy: state of the art

Arthroscopic synovectomy for first performed for haemophilic arthropathy in 1980 and was considered a major improvement over open surgical synovectomy, causing less postoperative morbidity and fewer hospitalizations, and preserving range of motion. Long-term results have shown that recurrent haemarthroses are decreased and joint function is preserved. Radiographic changes, however, suggest continued progression of the disease process. The procedure is technically demanding and requires considerable resources including skilled personnel, surgical equipment and an adequate supply of factor concentrate, all of which limit the availability of the procedure worldwide. Where this procedure fits into the treatment of chronic haemophilic synovitis depends very much on location and availability of resources. Consequently, the procedure should not be considered as the first-line approach for recurrent haemarthroses, but rather as a secondary procedure if alternative measures have failed.     

关节镜结合开放滑膜切除术治疗膝关节慢性滑膜炎

目的探讨关节镜结合开放滑膜切除术治疗膝关节慢性滑膜炎的手术方法及临床疗效。方法回顾性收集38例膝关节慢性滑膜炎患者的临床资料,其中18例在关节镜结合开放下行膝关节滑膜切除术,20例行全关节镜下滑膜切除术,分析两组患者的临床资料,从手术时间、切口长度、术后疼痛VAS评分、术后引流量、术后住院天数、术后膝关节屈曲活动度、Lysholm功能评分等方面进行比较。结果关节镜结合开放组在手术时间、术后引流量方面低于全关节镜组,在切口长度、术后疼痛VAS评分、术后住院天数方面高于全关节镜组,末次随访时两组膝关节屈曲活动度及Lysholm功能评分无显著性差异。结论关节镜结合开放滑膜切除术能彻底清理膝关节增生的滑膜,且手术操作方便,疗效满意。     

Arthroscopic synovectomy in rheumatoid arthritis of wrist

The wrist is the most commonly involved region of the upper extremity in rheumatoid arthritis (RA). Because the wrist joint becomes involved early during the disease course and its involvement rapidly progresses, and because the disabilities associated with progressive RA are significant, early and adequate treatment must be introduced to prevent disease progression. Various treatment methods can be employed to treat RA wrists based on radiological and clinical findings. Arthroscopic synovectomy is recommended for pain relief and functional recovery in early stage RA, and is also helpful in advanced staged RA with Larsen stage III. However, arthroscopic synovectomy is not recommended as an effective method of treatment for all patients with advanced radiographic changes. Nevertheless, arthroscopic synovectomy may delay the need for complex surgery, such as wrist arthrodesis or total wrist arthroplasty in selective cases. Although arthroscopic synovectomy of the wrist cannot improve grip strength or range of motion, it can reduce wrist pain and improve function, and thus facilitate return to work.
