[Objective]To evaluate the therapeutic effect of arthroscopic treatment for osteoarthritis of the knee,and explore the factors related to clinical outcome. [Methods]Three hundred and sixty-two patients with knee osteoarthritis were treated by arthroscopic surgery in the 88th hospital from May 2000 to November 2007. Of them,124 patients were followed-up completely. Quantified clinical data were input into computer and analyzed statistically by SPSS 16.0 software. Lysholm score was used to evaluate the therapeutic effect. Lysholm scores before surgery and at follow up were compared with paired t test. Patients were divided into different subgroups according to sex,locking,X -ray grade,arthroscopic grade and surgical methods. Lysholm scores at the final follow up of different subgroups were compared with variance analysis. The factors related to operation outcome were explored by using multiple stepwise linear regression analysis.[Results]One hundred and twenty-four patients were followed up from 7 to 96 months with an average of 39.6 months. Preoperative Lysholm score was (46.10?2.80),the score at follow up was (70.69+2.90),there was significant difference between preoperative score and at follow up (t=9.362,P0.05). The difference was significant between groups whether locking or not (F=10.654,P

BACKGROUND:Sodium hyaluronate injection after arthroscopic debridement of knee osteoarthritis can reduce postoperative pain and improve joint function, but there is a controversy on the time for the hyaluronate injection after arthroscopic debridement of knee osteoarthritis.
OBJECTIVE:To observe the time of hyaluronate injection after arthroscopic debridement of knee osteoarthritis, and to compare recent rehabilitation effect of knee sodium hyaluronate injection for knee function after
arthroscopic debridement of knee osteoarthritis between injection just after knee arthroscopy and injection 2 weeks after knee arthroscopy.
METHODS:The clinical data of 100 knee osteoarthritis patients undergoing sodium hyaluronate injection
immediately and 2 weeks after arthroscopic debridement were analyzed with prospective randomized control ed trial method, and the preoperative visual analog scale score, Lysholm score, 6 weeks postoperative visual analog scale score, 3 months postoperative visual analog scale score, and 3 months postoperative Lysholm score were recorded. The effects of recently rehabilitation of knee joint after surgery in two groups were compared.
RESULTS AND CONCLUSION:There was no significant difference in postoperative visual analog scale score between immediate injection group (6.52±2.38) and 2 weeks postoperative injection group (6.54±2.37). The preoperative Lysholm score in the immediate injection group (43.44±16.18) was lower than that in the 2 weeks postoperative injection group (51.12±16.3). The 6 weeks postoperative visual analog scale score in the immediate injection group (3.2±2.46) was significantly higher than that in the 2 weeks postoperative injection group (5.1±2.68). The 3 months postoperative visual analog scale score/Lysholm score in the immediate injection group (2.72±2.70)/(80.58±15.63) were significantly higher than those in the 2 weeks postoperative injection group (4.72±3.07)/(64.96±21.68). The results indicate that sodium hyaluronate injection immediately after arthroscopic debridement of knee osteoarthritis is more favorable for recent rehabilitation.

BACKGROUND:Bennett fracture repair is one of the problems for orthopedic surgeons, although there are a variety of clinical treatment for Bennett fracture, no treatment strategy is widely accepted. ＜br> OBJECTIVE:This study aims to provide evidence for developing an effective treatment strategy for Bennett fracture. ＜br> METHODS:A computer-based retrieval of PubMeb database (http://www.ncbi.nlm.nih.gov/PubMed), CNKI China Journal Ful-Text database (http://www.cnki.net/) and Wanfang database (http://g.wanfangdata.com.cn/) between January 2004 and July 2014 was performed by the first author. Meantime, Campbel ’s Operative Orthopaedics, Shiyong Guke Xue and other orthopedic monographs were manual y retrieved, to analyze research progress about Bennett fracture. ＜br> RESULTS AND CONCLUSION:A total of 37 literatures associated with Bennett fracture were involved in this study. Conventional closed reduction plaster or Kirschner wire fixation is characterized by low cost and easy operation, but it fails to achieve anatomical reduction. AO principle for fracture treatment has been widely accepted in recent years, the application of AO screw and AO plate is increasing in treatment of Bennett fracture, it can not only repair bone fracture but also repair and reconstruct the damaged ligament, but the cost is very high and secondary surgery is needed to remove the implant. Traditional Chinese orthopedics and integrated traditional and western medicine are experienced methods for treatments of Bennett fracture, and Chinese herbs have obvious symptomatic treatment effect and effectively improve the symptoms of patients. As the thumbs play a crucial role in the hand movement, the optimal treatment strategy for Bennett fractures has important clinical significance.
