High tibial osteotomy (HTO) is a surgical procedure to re-align varus or valgus mal-alignment of the knee. Medial opening wedge HTO is a surgical treatment of choice for knee varus mal-alignment with many advantages over lateral closing wedge HTO. However, the opening of the medial wedge alters the plane of the lateral tibial plateau, especially when the correction angle is large, which may be the cause of early arthritic changes of the lateral compartment. Many recent studies reported the changes in medial posterior slope after medial opening wedge HTO, which affected the biomechanics of the knee. This report presents uni-condyle HTO, a new surgical technique that corrects alignment of medial tibial plateau in both coronal and sagittal plane without affecting the plane of lateral tibial plateau.

Differential effects of tibia varus deformity on clinical outcomes following high tibial osteotomy and unicompartmental knee arthroplasty for moderate medial compartment osteoarthritis with moderate varus alignment.

Introduction: There is a lack of clinical evidence supporting the decision-making process between high tibial osteotomy (HTO) and unicomparmental knee arthroplasty (UKA) in gray zone indication, such as moderate medial osteoarthritis with moderate varus alignment. This study compared the outcomes between HTO and UKA in such cases and assessed the risk factor for not maintaining clinical improvements.
Materials And Methods: We retrospectively reviewed 65 opening-wedge HTOs and 55 UKAs with moderate medial osteoarthritis (Kellgren-Lawrence grade ≥ 3 and Ahlback grade < 3) and moderate varus alignment (5°< Hip-Knee-Ankle angle < 10°) over 3 years follow-up.

Medial opening wedge high tibial osteotomy (HTO) treats medial knee osteoarthritis by realigning the knee joint, though it still carries quite a high risk of complications. A new Variable Fixation Locking Screw technology, designed to gradually reduce construct stiffness and promote bone healing, aims to address these issues. This observational study evaluates the safety and effectiveness of this innovative approach in improving clinical outcomes.

Article Synopsis
- Knee pain often involves varus deformity and unicompartmental osteoarthritis, where high tibial valgus osteotomy (HTO) has emerged as an effective treatment option to delay joint replacement.
- A case report highlighted two patients with bilateral knee arthritis who underwent medial opening-wedge high tibial osteotomy using Dr. Saigal's plate, both achieving good range of motion and minimal complications post-surgery.
- Comprehensive evaluations, including radiological assessments and specific surgical techniques like the Miniaci Method, were employed to ensure successful outcomes, with both patients showing significant improvement after one year.
Medial and Lateral Meniscus Root Tear: Etiopathogenesis and Morphological Pattern in Indian Population.
Indian J Orthop
January 2025
Ivy Hospital, Mohali, Punjab India.
Objective: This study aims to enhance our understanding of the morphological pattern, causes and pathogenesis of meniscal root injuries in the Indian population.
Materials And Methods: Sixty-four patients with meniscus root tears were included in the study. The patients were categorized into two groups based on the location of the meniscus tear: Group 1 ( = 41) comprised patients with lateral meniscus root injury (LMRI), and Group 2 ( = 23) included patients with medial meniscus root injury (MMRI).
