Background Kashin–Beck disease (KBD) is an endemic, chronic osteoarthropathy that seriously affects joint function and can lead to severe knee deformity. Osteotomy is considered to be one of the effective methods for the treatment of this disease. Therefore, we designed a novel type of osteotomy named combined proximal tibial osteotomy (CPTO), which combines the characteristics of opening‐wedge high tibial osteotomy and tibial condylar valgus osteotomy. Case presentation We report the case of a 48‐year‐old male with knee pain and varus deformity who was diagnosed with KBD and varus knee osteoarthritis (Kellgren–Lawrence stage IV). Considering the patient's relatively young age, a varus deformity of the right knee of 16.79°, and an intra‐articular instability, we performed a CPTO treatment. In this procedure, we performed an L‐shaped osteotomy from the medial edge of the proximal tibia to the intercondylar eminence and an osteotomy from the medial side of the proximal tibia to the lateral side through the same incision, to adjust the leg alignment and the congruity of the joint by valgus correction. At 29 months follow‐up, this patient achieved satisfactory results, with a varus right knee of 2.87°. There was significant improvement in his right knee function, pain, and joint stability. Conclusions CPTO may be an acceptable treatment for KBD patients with severe knee varus deformity and intra‐articular instability. It can be considered as an alternative treatment, especially for patients with advanced osteoarthritis needing knee preservation.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
