PURPOSE: To prospectively evaluate elbow flexion force, cosmetic and clinical outcome of all-arthroscopic suprapectoral biceps tenodesis for isolated biceps lesions.
METHODS: Tenodesis was performed using a 6.25-mm absorbable interference screw for intraosseous fixation. Seventeen out of 24 patients (70.8 %, median age 49.0 ± 10.1 years; 10 = male) could be included for 24 months follow-up. Elbow flexion strength in 10° and 90° elbow flexion, the upward-directed force of the upper arm in the O'Brien position, objective evaluation of a Popeye-sign deformity and validated clinical scores (CMS, SST, ASES) were assessed preoperatively, 3, 6, 12 and 24 months postoperatively.
RESULTS: Elbow flexion strength in 90° improved significantly from 12 months onwards (P = 0.001) without significant difference to the contralateral arm from 3 months postoperatively (n.s.). At 24 months, an average increase of 46.4 % (median 37.7 %) from preoperative could be seen. The dominant arm was affected in 70.6 %. All scores showed a significant improvement 3 months postoperatively: SST (P = 0.003), ASES (P = 0.006) and total CMS (P < 0.001). Three patients (17.6 %) developed a distalization of the maximum biceps circumference of more than 20 % compared to preoperative.
CONCLUSIONS: All-arthroscopic proximal suprapectoral intraosseous single-limb biceps tenodesis for the treatment of isolated biceps lesions provides good-to-excellent clinical results with significant improvement of elbow flexion strength and clinical scores and no significant difference to the unaffected contralateral arm.
LEVEL OF EVIDENCE: IV.
