title: [Short-term results of reconstruction of elbow under arthroscopy in patients with elbow osteoarthritis].
abstract: OBJECTIVE
  To evaluate the short-term results of reconstruction of stiff elbow under arthroscopy technique in patients with elbow osteoarthritis.
  
  
  METHODS
  Between March 2006 and March 2009, 38 cases of elbow osteoarthritis with contracture were treated under arthroscopy technique. There were 26 males and 12 females with an average age of 47.8 years (range, 26-66 years). Unilateral side was affected in all cases, including 13 cases at the left side and 25 at the right side with 30 patients on the dominant side. The disease duration was more than 6 months. X-ray examination showed that 31 patients had free body, and 28 had osteophytosis. Seven patients had ulnar neuritis. The arthroscopy functional reconstruction was performed including synovectomy, free body removal, and osteocapsular arthroplasty.
  
  
  RESULTS
  All incisions healed by first intention. All patients were followed up 6-10 months (mean, 8 months). Transient radial nerve injury occurred in 1 case, re-adhesion of elbow joint in 1 case, and heterotopic ossification of brachial ulnar joint in 1 case at 6 months after operation. In 1 patient complicated by ulnar neuritis, the disorder of ulnar nerve was not improved, nervous symptoms disappeared after the re-operation of ulnar nerve relaxation after 2 months. The range of motion, Mayo Elbow Performance Score (MEPS), and visual analogue scale (VAS) for pain at 3 and 6 months had significant differences when compared with those before operation (P < 0.05), but had no significant difference between two time points after operation (P > 0.05). According to MEPS functional criteria, the results were classified as excellent in 20 cases, good in 15 cases, fair in 2 cases, and poor in 1 case at 6 months after operation, and the excellent and good rate was 92.1%. No new free body or osteophytosis occurred after operation by X-ray examination.
  
  
  CONCLUSIONS
  The arthroscopy is an effective technique to reconstruct the function of stiff elbow, which can obviously improve the range of motion and the function of elbow joint, and has good short-term results.
