Abstract

fetched live from OpenAlex

BACKGROUND: Anterior knee pain, with varus deformity and excessive external tibial torsion, can markedly impair function and quality of life. Although various surgical techniques address these deformities, dome-shaped osteotomy offers a promising approach for correcting malalignment while preserving joint integrity. This study evaluated clinical and radiological outcomes of dome-shaped osteotomy in patients with these combined deformities. METHODS: Twenty-eight knees from 21 patients with anterior knee pain, varus deformity (more than 5°), and excessive external tibial torsion (more than 30°) but acceptable hip anteversion (anteversion 30°) underwent dome-shaped tibial osteotomy proximal to the tibial tubercle. The group comprised nine male (32.1%) and 19 female patients (67.9%) with an average age of 28.5 years (17 to 45 years) and a mean body mass index of 19.9 kg/m 2 . Sixteen surgeries were done on right knees and the rest on left knees. Five female and two male patients were operated on bilaterally. Surgical steps included internal tibial rotation to correct axial deformity, medial translation as needed, valgus correction for optimal coronal alignment, and stabilization with a medial locking plate. Postoperative protocols included early mobilization with range-of-motion exercises. Outcomes were assessed using Western Ontario and McMaster Universities Osteoarthritis Index score (WOMAC scores) and The Knee injury and Osteoarthritis Outcome Score and radiographic evaluations of varus correction and patellar position. RESULTS: Postoperative Q-angle and thigh-foot angles normalized. WOMAC and pain scores markedly improved, with most patients reporting complete or high satisfaction ( P value <0.001). Complications were minimal, including transient peroneal nerve paresis in two knees and a small peroneal arterial aneurysm in one knee, which was managed conservatively. No infections, compartment syndrome, patella baja, or delayed/nonunion were observed. CONCLUSION: Dome-shaped osteotomy above the tibial tubercle is an effective surgical option for improving pain, function, and satisfaction in patients with anterior knee pain, varus deformity, and excessive external tibial torsion. LEVEL OF EVIDENCE: Level IV.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
