Purpose: To reveal the outcomes of partial medial meniscus posterior root tears following transtibial pullout repair compared with the outcomes of complete radial meniscus posterior root tears. Materials and Methods: We retrospectively evaluated 15 consecutive patients (male/female, 5/10; average age, 64.4 years) who underwent transtibial pullout repair for partial meniscus posterior root tears and compared their results with those of 86 consecutive patients who underwent the same surgery for complete meniscus posterior tears. All patients underwent second-look arthroscopy on average 1 year postoperatively, and a semi-quantitative meniscal healing score (anteroposterior width, stability, and synovial coverage, total 10 points) was evaluated. Medial meniscus extrusion was evaluated preoperatively and at second-look arthroscopy. Results: Postoperative clinical scores were not significantly different in the short term. However, second-look arthroscopy revealed a significant difference in repaired meniscal stability (partial tear; 3.3 points, complete tear; 2.3 points, p<0.001) and total meniscal healing scores (partial tear; 8.3 points, complete tear; 7.1 points, p<0.001). Medial meniscus extrusion progression was significantly different (partial tear; 0.4 mm, complete tear; 1.0 mm, p<0.001). Conclusion: Partial meniscus posterior root tears showed better meniscal healing and less medial meniscus extrusion progression following pullout repair than complete meniscus posterior root tears.
