Arthroscopic Partial Meniscectomy Time Window

Effect of Early vs Delayed Arthroscopic Partial Meniscectomy on the Knee Function of Patients With Degenerative Meniscus Lesions

The purpose was to assess knee function outcomes between early arthroscopic partial meniscectomy(APM) and delayed APM for patients with degenerative meniscus lesions(DMLs)

Whether early APM surgery or delayed APM surgery will more benefit for patients with DMLs. The study was to determine the early APM vs delayed APM effect on knee function outcomes for patients with DMLs for 1 year follow-up.
