Since there are no reports of proximal tibiofibular joint (PTFJ) dislocation caused by EDS, little is known about the long-term course of this disease. A woman in her 40s presented with a posterolaterally depressed tibial condyle and severe valgus deformity caused by a long-standing PTFJ dislocation due to EDS. Considering the pathology, posterolateral open-wedge high tibial osteotomy (PLOWHTO) and medial closed-wedge distal femoral osteotomy were performed according to the deformity analysis. A favourable short-term clinical outcome was obtained and the PTFJ dislocation was reduced over time. Although PLOWHTO has several pitfalls, it is a logical and useful surgical technique that can help treat posterolateral dysplasia of the tibial plateau concomitant with severe valgus deformity, regardless of joint laxity, if performed with attention to pitfalls.<\/jats:p>","DOI":"10.1136\/bcr-2022-250308","type":"journal-article","created":{"date-parts":[[2022,11,29]],"date-time":"2022-11-29T10:35:10Z","timestamp":1669718110000},"page":"e250308","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":3,"title":["Proximal
