Management was complicated by extensive scarring and 8 prior residual limb revisions. To address instability, the patient underwent medial patellofemoral ligament (MPFL) reconstruction using an ipsilateral semitendinosus autograft, following MRI verification of tendon viability. At 12-month follow-up, stability was restored, allowing successful return to active prosthesis use and mobility without complications.<\/jats:p>\n <\/jats:sec>\n \n Conclusion:<\/jats:title>\n MPFL reconstruction using an ipsilateral autograft effectively treats instability in below-knee amputees while avoiding donor-site morbidity in the contralateral limb.<\/jats:p>\n <\/jats:sec>","DOI":"10.2106\/jbjs.cc.26.00007","type":"journal-article","created":{"date-parts":[[2026,6,16]],"date-time":"2026-06-16T23:00:25Z","timestamp":1781650825000},"update-policy":"https:\/\/doi.org\/10.1097\/lww.0000000000001000","source":"Crossref","is-referenced-by-count":0,"title":["Medial Patellofemoral Ligament Reconstruction for Patellar Instability in a Patient with Below-Knee Amputation"],"prefix":"10.2106","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2815-5616","authenticated-orcid":false,"given":"Irmak","family":"Kavc\u0131","sequence":"first","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Ege University Faculty of Medicine, Izmir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3315-6920","authenticated-orcid":false,"given":"Melekper Elcil","family":"Kaya Bi\u00e7er","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Traumatology, Ege University Faculty of Medicine, Izmir, Turkey"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","published-online":{"date-parts":[[2026,4]]},"reference":[{"issue":"7","key":"bib1-20260801","doi-asserted-by":"crossref","first-page":"2772","DOI":"10.1007\/s00167-022-07222-w","article-title":"MPFL repair after acute first-time patellar dislocation results in lower redislocation rates and less knee pain compared to rehabilitation: a systematic review and meta-analysis","volume":"31","author":"Le","year":"2023","journal-title":"Knee Surg Sports Traumatol Arthrosc."},{"issue":"12","key":"bib2-20260801","doi-asserted-by":"crossref","first-page":"3313","DOI":"10.1177\/03635465221130448","article-title":"Double-limb graft versus single-limb graft medial patellofemoral ligament reconstruction for recurrent patellar dislocation: a meta-analysis of randomized controlled trials and cohort studies","volume":"51","author":"Pang","year":"2023","journal-title":"Am J Sports Med."},{"issue":"1","key":"bib3-20260801","doi-asserted-by":"crossref","first-page":"23259671231221239","DOI":"10.1177\/23259671231221239","article-title":"Comparison of failure rates at long-term follow-up between MPFL repair and reconstruction for recurrent lateral patellar instability","volume":"12","author":"Kruckeberg","year":"2024","journal-title":"Orthop J Sports Med."},{"issue":"5","key":"bib4-20260801","doi-asserted-by":"crossref","first-page":"553","DOI":"10.1097\/01241398-198709000-00010","article-title":"Patellar instability in juvenile amputees","volume":"7","author":"McIvor","year":"1987","journal-title":"J Pediatr Orthop."},{"issue":"2","key":"bib5-20260801","doi-asserted-by":"crossref","first-page":"91","DOI":"10.1016\/j.ijscr.2013.12.021","article-title":"Does form follow function in trochlear dysplasia?
