Does Obesity Negatively Affect the Functional Results of Arthroscopic Partial Meniscectomy? A Retrospective Cohort Study

Purpose The purpose of this study was to evaluate the impact of body mass index (BMI) on early functional results of patients who undergo isolated partial meniscectomy. Methods The functional results for 1,090 patients who underwent partial meniscectomy, in 2 different orthopaedic clinics, were evaluated retrospectively. The study includes cases with arthroscopic partial meniscectomy for isolated meniscal tears; patients with concomitant knee pathology were excluded. Three hundred forty-one (31%) patients with isolated lateral meniscal tears, 628 (58%) patients with isolated medial meniscal tears, and 121 (11%) patients with both medial and lateral meniscal tears underwent arthroscopic partial meniscectomy. We divided these patients into 3 subgroups on the basis of their BMI;
