Mastering the Geometry of Joint Preservation: A Comprehensive Review of Preoperative Planning, Multiplanar Alignment, and Patellofemoral Dynamics in Medial Opening Wedge High Tibial Osteotomy

Abstract

A biological substitute for arthroplasty, medial opening wedge high tibial osteotomy (MOWHTO) has resurfaced as a dependable technique to stop the advancement of medial compartment gonarthrosis [1]. When surgeons treat the surgery only as a coronal plane repair, it has a reputation for being unpredictable despite its potential [2]. The implant by itself cannot ensure success; careful patient selection and precise geometrical planning are necessary [3]. In order to address the anatomical and radiological conditions necessary for real joint preservation, this analysis moves away from implant biomechanics [4]. We examine contemporary changes in body mass index (BMI) and age indicators, prioritizing physiological potential over temporal constraints [5]. Preoperative templating is thoroughly examined, with a particular comparison between the contemporary computerized tracking of the weight-bearing line and the traditional Miniaci method [6]. We also investigate the osteotomy's unexpected effects on the sagittal plane [7]. Unexpected changes in the posterior tibial slope significantly change the kinematics of the knee, endangering the integrity of the anterior cruciate ligament and changing contact mechanics [8]. We also assess the patella infera, or inevitable patellofemoral descent, that results from elevation of the joint line [9]. Orthopedic surgeons can predictably transmit load to the lateral compartment without developing new, iatrogenic joint diseases by mastering these multiplanar factors [10].
