Synopsis

Keywords: Cartilage, Joints, Meniscus, Knee, Patient Reported OutcomesMeniscectomies are common but not always successful in treating degenerative meniscus tears. Preoperative patient reported outcomes (PROs) and quantitative MRI could help surgeons decide candidacy for meniscectomy. This study demonstrated that pre-operative T2 relaxation times in the medial central femoral cartilage are correlated to pre-operative PROs in patients with degenerative meniscal tears and are predictive of 1 and 2-year changes in PROs post-operation. This study suggests patients who have longer T2 relaxation times pre-operation might not benefit as much from a meniscectomy.
