2023 Annual Meeting Biologics-Survivorship of the Subchondroplasty Procedure in Patients With Bone Marrow Lesions

Survivorship of the Subchondroplasty Procedure in Patients With Bone Marrow Lesions

Video Transcription

Video Summary

Dorian Wood presented a study on subchondroplasty, a procedure injecting biosorbic cement into subchondral bone lesions in arthritic knees to reduce pain and delay knee replacement. Analyzing 214 patients over five years, survivorship free from total knee arthroplasty was 73%. Age over 50 and severe (grade 4) lesions significantly increased the likelihood of needing knee replacement, with only 59% survivorship in older patients with grade 4 lesions. The study suggests careful patient counseling and calls for randomized trials comparing subchondroplasty to arthroscopy alone to confirm its effectiveness.
