Impact of the Posterior Tibial Slope on Medial Meniscus Posterior Root Tear Healing Based on Second-Look Arthroscopy

This study investigates the impact of posterior tibial slope (PTS) on the healing outcomes of repaired medial meniscus posterior roots, hypothesizing that a steeper PTS is linked to poorer healing. The findings reveal that patients with a PTS of 8.3° or greater exhibited significantly compromised healing status, suggesting that increased PTS may lead to lax healing and potential meniscal extrusion post-repair. Thus, the authors conclude that a higher PTS could negatively influence postoperative healing and clinical outcomes in these patients.
