The Management of Extensor Mechanism Disruption After Total Knee Arthroplasty: A Systematic Review

Sports Med Arthrosc Rev. 2017 Mar;25(1):41-50. doi: 10.1097/JSA.0000000000000139.


We performed a literature search on PubMed, Web of Science, Science Direct/Scopus, Google Scholar, and Google to evaluate results of several techniques to manage disruption of the extensor mechanism after total knee arthroplasty. Different methods to manage extensor mechanism disruption are available at present, with no level I studies informing surgeons in an evidence-based fashion. Primary repair is not indicated. Allograft reconstruction could be effective, providing that appropriate surgical technique and allograft tensioning are implemented.
