ABSTRACT
BACKGROUND: There has been controversy regarding the pathogenesis and treatment of lateral epicondylitis. Different surgical techniques for the treatment of lateral epicondylitis prescribed. The purpose of this study was to evaluate the short-term outcomes of arthroscopic management including resection of the radio-capitellar capsular complex, using different validated scores. METHODS: In this study, arthroscopic resection of a capsular fringe complex was done beside debridement of the undersurface of Extensor Carpi Radialis Brevis (ECRB). Thirty-one patients with recalcitrant lateral epicondylitis for a minimum of 6 months had surgery. In all patients, a collar-like band of radio-capitellar capsular complex was found to impinge on the radial head and subluxate into the radio-capitellar joint with manipulation under direct vision. Outcomes were assessed using Mayo Elbow Performance Index (MEPI), the Patient-Rated Tennis Elbow Evaluation (PRTEE), and the Disability of the Arm, Shoulder, and Hand (DASH), beside visual analog scale (VAS) for pain and satisfaction criteria. RESULTS: After arthroscopic surgery, overall satisfaction was extremely positive, over the 31 patients, 93.5% of the patients are satisfied. The mean score for pain improved from 8.64 to 1.48 points. The total PRTEE improved from 55.53 to 10.39 points. The mean MEPI score was improved from 61.82 to 94.10 points. DASH score also improved from 24.46 to 4.81 points. All improvements are statistically significant (P < 0.05). CONCLUSION: Arthroscopic release of ECRB in patients with chronic lateral epicondylitis is a reproducible method with a marked improvement in function within a short period, with special consideration for resection of radio-capitellar capsular complex.
ABSTRACT
PURPOSE: The proximal part of the long head of the biceps muscle has become a recognized cause of significant shoulder pain. Tenodesis of the long head of the biceps has been advocated as a treatment for pain resulting from biceps tendonopathy, biceps instability, and biceps tendon tears. All of these pathologies may be encountered during rotator cuff, SLAP or Bankart surgery, or in isolation. Several techniques have been described for this tenodesis, including various arthroscopic and subpectoral methods. METHODS: We present a modified bone bridge technique of Mazzocca et al., for subpectoral biceps tenodesis. In this technique we tenodese the tendon through two bone tunnels back over the muscle itself without implants. RESULTS: Application of this technique on 30 patients (ages 25-48 years) with short-term follow-up of 12-18 months showed statistically significant improvement (P value < 0.05) of the mean Constant and Oxford shoulder scores (pre-operative mean scores were 39.03 and 21.3, respectively, while postoperative mean scores were 76.43 and 44.8, respectively). CONCLUSION: This technique has potential advantages as it allows the possibility of adjusting the tension of the biceps tendon before final suturing, in addition to quicker soft tissue healing.
