Influence of Previous Arthroscopic Meniscectomy on Midterm to Long-term Outcomes After Medial Open-Wedge High Tibial Osteotomy

Background: Few studies have evaluated the clinical and radiological outcomes of medial open-wedge high tibial osteotomy (MOWHTO) in patients who had previously undergone arthroscopic meniscectomy. Purpose: To verify whether previous arthroscopic meniscectomy affects the clinical and radiological ou...

Description
Summary:Background: Few studies have evaluated the clinical and radiological outcomes of medial open-wedge high tibial osteotomy (MOWHTO) in patients who had previously undergone arthroscopic meniscectomy. Purpose: To verify whether previous arthroscopic meniscectomy affects the clinical and radiological outcomes of MOWHTO. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 183 consecutive knees that underwent MOWHTO and had a minimum 5 years of follow-up were retrospectively reviewed. We compared the preoperative and postoperative clinical and radiological data of 32 knees with a history of meniscectomy (previous meniscectomy group) to 151 control knees without a history of meniscectomy. Cartilage status was also compared at first- and second-look arthroscopic surgery according to the International Cartilage Repair Society grading system. Failure was defined as conversion to total knee arthroplasty or revision MOWHTO. On subgroup analysis, the previous meniscectomy group was divided into 2 subgroups based on the time from meniscectomy to MOWHTO (
