Combined Proximal Tibial Osteotomy for Adult Kashin-Beck Disease with Severe Varus Knee Osteoarthritis: Case Report and Literature Review.
Review in Orthopaedic surgery, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundKashin-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.
conclusionsCPTO 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.
