ARTHROSCOPIC SINGLE OR DOUBLE ROW REPAIR OF ISOLATED FULL THICKNESS SSP TEAR – PROSPECTIVE RESULTS AFTER 24 MONTHS

European Federation of National Associations of Orthopaedics and Traumatology (EFORT) - 12th Congress



Abstract

Aim

The purpose of this study was to evaluate the results after arthroscopic reconstruction of isolated SSP lesions. Does double row repair in smaller lesions lead to better results and a lower retear rate?

Method

80 patients with an isolated full thickness SSP tear were divided into 2 groups. Group 1 (27 men, 13 Frauen, average age 57 y.) was repaired using a single row technique with 2 anchors (Mitek Fastin) with arthroscopic Mason-Allen stiches. Group 2 was repaired using a double row technique using 1 medial anchor (Mitek Fastin) and 2 lateral anchors (Versalok). PreOP an ultrasound and MRI was obtained as well as standard x-rays (a.p., outlet-view, transaxial). Included to this study were only patients matching the following criteria: intraoperative cartilage lesions ≤ Outerbridge Grade2, fatty degeneration ≤ Goutallier Grade 2, ap extent of the tear < 2,5 cm. Prospective follow up after 6, 12 and 24 months using UCLA and Constant Score as well as MRI at last follow up.

Results

37 patients in group 1 and 36 patients in group 2 were completely evaluated. Both groups showed improvement in Constant Score from 49,3 to 89,4 in group 1 (single row) compared to 47,6 and 90,7 in group 2 (Double Row). MRI at last follow up showed 4 retears in the single row group and 3 retears in the double row group. 1 shoulder in the double row group needed revision due to a loose anchor.

Discussion

We could not find any significant difference between clinical results and retear rate using a single or double row suture anchor configuration in isolated full thickness SSP tears.
