This ACE Report is a summary of a conference presentation or abstract. The information provided has limited the ability to provide an accurate assessment of the risk of bias or the overall quality. Please interpret the results with caution as trials may be in progress and select results may have been presented.
190 patients undergoing partial meniscectomy during which chondral lesions were identified were randomized to either debridement or no debridement of the chondral lesions. Patients were followed up for 12 months postoperatively for clinical scores related to pain, function, and quality of life. At 12 months, Please login to view the rest of this report.

Why was this study needed now?
Chondral lesions are often encountered during meniscectomy procedures. While debridement can be performed on these lesions during the surgical procedure it is unknown if it provides significant benefit over simple observation.
What was the principal research question?
When chondral lesions are found during partial meniscectomy, is there any significant difference in clinical outcome after 1 year between those which are debrided versus left for observation?
Population: 190 patients undergoing partial meniscectomy and intraoperative identification of Outerbridge grade II-IV chondral lesions.
Intervention: CL-Deb group: During surgery, debridement was performed for identified chondral lesions. (n=98)
Comparison: CL-noDeb group: Debridement was not performed for chondral lesions. (n=92)
Outcomes: The primary outcome was the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) pain score. Secondary clinical scores included the WOMAC function and stiffness subscales, the Knee Injury and Osteoarthritis Outcomes Score (KOOS), a visual analog scale (VAS) for pain, and the Short Form 36-Item General Health Survey (SF-36).
Methods: RCT
Time: Follow-up scheduled for 8-12 days, 6 weeks, 3 months, 6 months, and 1 year postoperatively.
