Osteonecrosis of the Knee after Arthroscopic Partial

arthroscopic meniscectomy is very rare and only about a score of cases has been reported since first described by Brahme et al.3) in 1991. Santori et al.4) suggested that abnormal load transfer after meniscectomy that results in chondral damage, inflammation, edema, and increased bone marrow pressure is the major cause of osteonecrosis. In spite of the rarity, osteonecrosis of the knee after arthroscopic meniscectomy requires early diagnosis and proper treatment to prevent it from developing into a serious complica-tion. In this report, we present a case of osteonecrosis after partial medial meniscectomy that exhibited rapid progression with a review of the literature. Case Report A 50-year-old male visited our clinic with a major complaint of pain in the right knee that had started five days earlier. He had no history of trauma and complained of a pulling sensation behind the right knee and giving way symptoms when walking down stairs. The patient had been working as a medical techni-cian carrying gurneys for 21 years and had no significant medical history or history of trauma, alcohol abuse, and intra-articular steroid injections. Physical examination revealed tenderness over the medial femoral condyle but no edema. The range of motion and lower limb alignment were normal. McMurray’s test was negative, joint instability was not present, and early radiography was normal (Fig. 1), Magnetic resonance imaging (MRI) showe
