Graft Site Morbidity in Elbow Ligament Reconstruction Procedures: A Systematic Review

Background: It is unclear which tendon harvest for ulnar or lateral collateral ligament reconstruction has the lowest graft site morbidity rate. Purposes: To obtain graft site morbidity rates after tendon harvest for ulnar and lateral collateral ligament reconstruction procedures. Study Design: Systematic review/Meta-analysis. Methods: Studies were eligible if (1) patients had undergone elbow ligament reconstruction procedures; (2) original data for at least 5 patients were available; (3) the article was written in English, German, or Dutch; (4) a full-text article was available; and (5) information about graft site morbidity was available. The review excluded studies about complicated elbow ligament reconstruction procedures due to initial fractures, revision procedures, or circumferential graft techniques; animal studies; (systematic) reviews; and expert opinions. Because the majority of studies were case reports, no selection form or overall scoring system to evaluate methodological quality was used. Results: The review included 619 patients with an ulnar or lateral collateral ligament reconstruction procedure. The autograft types used included palmaris longus tendon (58%), gracilis tendon (24%), semitendinosus tendon (8%), triceps tendon (7%), toe extensor tendon (<2%), plantaris tendon (<2%), extensor carpi radialis longus tendon (<1%), and Achilles tendon (<1%). Conclusion: Graft site morbidity occurred in 1% of the patients after an ulnar or lateral collateral ligament reconstruction procedure. This study did not have enough samples of all the autograft types to conclude that autograft type and graft site morbidity are unrelated.
