Klinische Ergebnisse nach Refixation proximaler Hamstring-Sehnen-Rupturen unter Berücksichtigung verschiedener Ankersysteme

Background: Injuries to the hamstring muscles and tendon complex are among the most frequent muscular injuries with proximal hamstring tendon avulsion being a particularly severe form. The surgical treatment of these injuries is superior to conservative management with respect to patient satisfaction, recovery of muscle strength and function as well as return to sport rates. It is therefore the method of choice. Objective: Presentation and comparison of the surgical results after treatment with titanium, polyether ether ketone (PEEK) and all suture anchors. Material and methods: A systematic search was carried out in the PubMed medical database and the results are summarized. Results: All systems exhibit comparable biomechanical properties regarding elongation and ultimate failure load. Tendon repair with these anchors results in good to excellent clinical outcomes and shows high return to sport and low complication rates. Patient satisfaction after hamstring tendon repair is reported to be over 90% and return to sport rate is 80–100%. The muscle strength recovers to 80–90% in comparison to the contralateral side. Conclusion: All available anchors systems provide good to excellent clinical outcomes and an explicit advantage for one anchor system could so far not be shown.
