Chondral Debridement Graph for OBuzzMore than 900,000 patients every year undergo knee arthroscopy in the US. Many of those procedures involve a partial meniscectomy to address symptomatic meniscal tears. Surgeons “scoping” knees under these circumstances often encounter a chondral lesion—and most proceed to debride it.

However, in the July 5, 2017 issue of JBJS, Bisson et al. report on a randomized controlled trial that suggests there is no benefit to arthroscopic debridement of most unstable chondral lesions when they are encountered during partial meniscectomy. With about 100 patients ≥30 years old in each group, the authors found no significant differences in function and pain outcomes between the debridement and observation groups at the 1-year follow-up.
