Meniscal degeneration is a process that often occurs due to gradual wear and is commonly associated with advanced knee osteoarthritis. 404-407. Degenerative meniscus tears, part of the aging process, are the most common reason for knee arthroscopy because many primary care physicians and orthopedic surgeons believe that meniscus tears always require surgery.

Mucoid degeneration (MD) of the meniscus has received little attention. Patients underwent intra-articular knee steroid/bupivacaine injection and were followed clinically for a minimum of 6 months. Sixty patients who had clinical and MRI evidence of a symptomatic degenerative tear of the posterior horn of the medial meniscus, isolated or accompanied by additional features of degenerative arthritis, who had failed conservative approaches (physiotherapy, non-steroidal anti-inflammatories, and 3 months rest/knee bracing) were included in the study. Open Orthop J.
