High Tibial Osteotomy Techniques in Knee Joint Rehabilitation

High tibial osteotomy is a joint-preserving procedure that realigns the mechanical axis of the lower limb to unload the medial compartment of the knee. By creating a controlled cut in the proximal tibia, either an opening wedge or closing wedge is used to correct varus malalignment, redistribute load and promote cartilage regeneration. Techniques have evolved from simple uniplanar cuts to biplanar osteotomies incorporating advanced plate fixation or patient-specific instrumentation. Clinical aims include pain relief, functional improvement and delaying arthroplasty in younger or active patients. Biomechanical principles underpinning these procedures involve precise preoperative planning to achieve a slight valgus correction, maintenance of the posterior tibial slope and preservation of knee kinematics. Rehabilitation protocols emphasise early mobilisation and weight-bearing to facilitate bone healing and restore range of motion.

A comprehensive meta-analysis compared long-term survivorship between opening-wedge and closing-wedge osteotomies, pooling data over a ten-year horizon. Results indicate similar survival at five years, with opening-wedge techniques demonstrating a modest advantage at ten years in postponing conversion to total knee replacement. The analysis incorporated studies with diverse fixation methods and highlighted that sustained mechanical axis correction correlates with durable clinical benefit. Findings underscore the importance of procedural choice in achieving optimal longevity and inform surgical decision-making in varus osteoarthritis management.

High Tibial Osteotomy Techniques in Knee Joint Rehabilitation publication trend

The graph below shows the total number of articles in high tibial osteotomy techniques in knee joint rehabilitation across all publications each year (not limited to Nature Index journals).

Technical terms

High tibial osteotomy (HTO): A surgical procedure that realigns the tibia to redistribute load across the knee joint.

Varus deformity: An inward angulation of the distal segment of a bone or joint, leading to increased medial compartment load.

Medial opening-wedge osteotomy: A technique involving an osteotomy on the inner side of the tibia and gradual opening to achieve valgus alignment.

Biplanar osteotomy: A two-plane bone cut that increases stability and promotes faster union by extending the osteotomy into the sagittal plane.

Posterior tibial slope (PTS): The angle of the tibial plateau in the sagittal plane, critical for knee kinematics and ligament tension.
