TL;DR: Reduction of meniscal extrusion seems to be appropriate to preserve its protective role against progression of cartilage degeneration after complete healing at PRTMM and show significant functional improvement in both the suture anchor repair and pullout suture repair groups.

Abstract: Purpose To evaluate functional and radiographic results of arthroscopic suture anchor repair for posterior root tear of the medial meniscus (PRTMM) and compare with pullout suture repair. Methods From December 2006 to August 2008, 51 consecutive patients underwent arthroscopic repair of PRTMM at our hospital. The repair technique was switched over time from pullout suture repair (group 1) to suture anchor repair (group 2). Of the patients, 6 were lost to follow-up, leaving a study population of 45 patients, with 22 menisci (48.9%) in group 1 and 23 (51.1%) menisci in group 2. The mean follow-up duration was 25.9 months (range, 24 to 27 months) in group 1 and 26.8 months (range, 24 to 28 months) in group 2. Compared variables included International Knee Documentation Committee criteria, Kellgren-Lawrence grade, gap distance at PRTMM, structural healing, meniscal extrusion, and cartilage degeneration of the medial femoral condyle. Results At 2 years postoperatively, both groups showed significant improvements in function ( P P > .05) compared with preoperatively. On magnetic resonance imaging, the gap distance at PRTMM was 3.2 ± 1.1 mm in group 1 and 2.9 ± 0.9 mm in group 2 preoperatively ( P > .05). Complete structural healing was seen in 11 cases in group 1 and 12 cases in group 2 ( P > .05). Mean meniscal extrusion of 4.3 ± 0.9 mm (group 1) and 4.1 ± 1.0 mm (group 2) preoperatively was significantly decreased to 2.1 ± 1.0 mm (group 1) and 2.2 ± 0.8 mm (group 2) postoperatively ( P Conclusions For PRTMM, our results show significant functional improvement in both the suture anchor repair and pullout suture repair groups. Reduction of meniscal extrusion seems to be appropriate to preserve its protective role against progression of cartilage degeneration after complete healing at PRTMM. Level of Evidence Level III, prospective therapeutic comparative study.

TL;DR: Torn MMPRs had decreased numbers and disorganized courses of collagen fibers, which might provide a histopathological reason for the low healing rate after MMPR repair and negatively affect meniscal healing, function, and long-term survival after root repair.

TL;DR: This chapter mainly focuses on medial meniscus posterior root tear which is the point of attention nowadays because it is the common degeneration process and can lead to early-onset osteoarthritis of the knee without treatment.

TL;DR: It was concluded that, to ensure maximum uniformity in grading x rays in field surveys and therapeutic trials, all readings should be made by the same observer, preferably at a single session.

Biomechanical Consequences of a Tear of the Posterior Root of the Medial Meniscus: Similar to Total Meniscectomy
TL;DR: Root repair was successful in restoring joint biomechanics to within normal conditions and significant changes in contact pressure and knee joint kinematics due to a posterior root tear of the medial meniscus were demonstrated.

The role of meniscal root pathology and radial meniscal tear in medial meniscal extrusion
TL;DR: A significant number of cases with no or minimal evidence of DJD (20%) had ≥3 mm MME, suggesting that MME precedes, rather than follows, the development ofDJD.

TL;DR: In subjects with osteoarthritis, increasing meniscal subluxation on MR correlates with the severity of joint space narrowing and is highly associated with symptomatic knee OA.
