ARTHROSCOPIC TREATMENT OF TYPE II SLAP LESIONS. TENODESIS OF THE LONG BICEPS, AN ALTERNATIVE TO REINSERTION?

Abstract

Purpose of the study: Arthroscopic reinsertion of SLAP lesions is the most commonly used approach. Tenodesis of the long biceps could be proposed as an alternative to reinsertion. The purpose of our study was to report the results of tenodesis and reinsertions for the treatment of type II SLAP lesions.

Material and methods: This was a consecutive monocentric comparative series analyzed retrospectively. Isolated type II SLAP lesions treated arthroscopically were retained for study: 25 cases treated from January 2000 to May 2004. Exclusion criteria were: associated instability, associated cuff tears, history of surgery. The long biceps tendon was reinserted on the glenoid tubercle using two threads mounted on resorbable anchors in ten patients (all men), mean age 27.5 years (range 19–57 years). Tenodesis of the long biceps in the gutter was performed in fifteen patients (six women and nine men), mean age 52.2 years (range 28–64 years). All patients were reviewed by an independent observer.

Results: In the reinsertion group, mean follow-up was 35 months (range 12–57 months). Three patients had revision tenodesis due to persistent pain and three others were disappointed because they were unable to resume their former sport. Four others were very satisfied. The mean Constant score improved from 65 to 83 points. Force was 16 kg in flexion and 5 kg in supination. In the tenodesis group, mean follow-up was 34 months (range 12–56 months). There were no revision procedures in this group. Subjectively, one patient was disappointed (atypical pain), two were satisfied and 12 very satisfied. The mean Constant score improved from 59 to 89 points. Force was 14.5 kg in flexion and 4.8 kg in supination.

Discussion: This series showed that results obtained with reinsertions can be disappointing: three revisions and three disappointed patients among ten procedures. In the tenodesis group, 14 of 15 patients were satisfied or very satisfied. Tenodesis of the long head of the biceps can be considered as an alternative to reinsertion for the treatment of type II SLAP lesions, particularly in older athletes.
