Purpose

The purpose of this study was to examine the results of arthroscopic debridement for isolated degenerative joint disease of the shoulder.

Methods

We retrospectively identified 81 patients who had arthroscopic debridement to treat glenohumeral arthritis. Of these patients, 71 (88%) were available for follow-up. The preoperative Simple Shoulder Test score, American Shoulder and Elbow Surgeons score, Short Form 12 score, visual analog scale score for pain, and range of motion were recorded. These were compared against postoperative scores by use of the statistical paired t test. In addition, patients completed postoperative University of California, Los Angeles; Constant; and Single Assessment Numeric Evaluation scores. Forty-six preoperative radiographs were blindly evaluated and classified. Finally, the need for subsequent shoulder arthroplasty was recorded.

Results

The mean follow-up for the 55 patients who did not progress to arthroplasty was 27 months. The mean preoperative and postoperative American Shoulder and Elbow Surgeons, Simple Shoulder Test, and pain visual analog scale scores all significantly improved (P < .05). Furthermore, range of motion significantly improved (P < .05) in flexion, abduction, and external rotation. Additional postoperative scores were as follows: University of California, Los Angeles, 28.3; Single Assessment Numeric Evaluation, 71.1; Constant score for affected shoulder, 72.0; and Constant score for unaffected shoulder, 78.5. Of the patients, 16 (22%) underwent arthroplasty at a mean of 10.1 months after debridement. Radiographic review showed that 13 shoulders with a mean joint space of 1.5 mm and grade 2.4 arthrosis went on to have shoulder arthroplasty. In contrast, 33 shoulders with a mean joint space of 2.6 mm and grade 1.9 arthrosis did not go on to have shoulder arthroplasty.

Conclusions

Patients with residual joint space and an absence of large osteophytes can avoid arthroplasty and have increased function with decreased pain after arthroscopic debridement for degenerative joint disease. Significant risk factors for failure include the presence of grade 4 bipolar disease, joint space of less than 2 mm, and large osteophytes.

Methods

The study was reviewed by our institutional review board, and all patients provided informed consent. From 2001 to 2007, the senior surgeons' operative databases were reviewed based on Current Procedural Terminology coding, and 81 patients were retrospectively identified who had arthroscopic debridement for the management of glenohumeral arthritis. Of these patients, 71 (88%) were available for follow-up. The procedure was performed by 1 of 4 surgeons at a single institution. Inclusion criteria

Results

Seventy-one patients were available for follow-up and were segmented into either an arthroplasty or non-arthroplasty subset; the mean age was 47 years (range, 18 to 77 years). At final follow-up, 16 (22%) had undergone shoulder replacement at a mean of 10.1 months (range, 2.5 to 27.2 months; SD, 6.41) after debridement; 4, hemiarthroplasty; 9, total shoulder arthroplasty; and 3, humeral head allograft. The remaining 55 patients comprise the non-arthroplasty subset. There were no statistically

Discussion

The principal results of our study show that arthroscopic debridement can be a successful treatment adjunct for degenerative joint disease of the shoulder in select patients. We treated 71 patients with glenohumeral arthritis with arthroscopic debridement and followed them up at a mean of 27 months. Of these patients, 16 (22%) went on to shoulder replacement at a mean of 10 months. These patients routinely had less than 2 mm of joint space on the preoperative anteroposterior radiograph with

Conclusions

Patients with residual joint space and an absence of large osteophytes can avoid arthroplasty and have increased function with decreased pain after arthroscopic debridement for degenerative joint disease. Significant risk factors for failure include the presence of grade 4 bipolar disease, joint space of less than 2 mm, and large osteophytes.

    Results of arthroscopic management of glenohumeral arthritis in the literature are mixed, with some series showing improvement and others with outcomes that are more disappointing. Patients with small isolated chondral lesions or small osteophytes tend to do better than those with multifocal or larger lesions or large osteophytes.27-34 In addition to arthroscopic debridement, microfracture techniques or chondral transplant techniques have also been described in the shoulder for glenohumeral chondral defects, although there is little long term information in the literature regarding outcomes following these procedures.27,33-41,42
