The Sound of Cartilage Repair: The Importance of Using Pitch and Volume Cues in Cartilage Restoration Surgery.

Articular cartilage defects are common and can result in substantial pain and disability, prompting operative intervention, which commonly includes chondral debridement. Controlled defect preparation up to but not beyond the calcified cartilage layer is key to clinical success, but this remains technically challenging. We present a technique highlighting the substantial decrease in curette stroke volume and associated shift to a lower pitch when achieving satisfactory open cartilage defect debridement. These audiologic cues correlate well with histologic accuracy of debridement. Therefore, quantifiable pitch and volume changes serve as valuable technical cues for precise defect preparation at the time of joint preservation surgery. I: knee, II: cartilage.
