Abstract Purpose To evaluate patient MRI results, demography and clinical outcome following transtibial repair of lateral and medial meniscal posterior root tears. Methods Patients treated with transtibial repairs of posterior meniscal root tears from 2015 through 2018 performed pre- and postoperative MRI scans. Outcome measures were continuity/discontinuity of the meniscal root and change in meniscal extrusion on MRI. Other outcomes were KOOS, Lysholm score, Tegner activity scale and the Global Rate of Change (GRoC) score for function and pain at follow-up. Study design Retrospective case-series. Results Of 41 patients, 36 attended follow-up at mean 26 (12–38) months postoperatively. At follow-up, 11 out of 18 lateral meniscus posterior root tear (LMPRT) versus 5 out of 18 medial meniscus posterior root tear (MMPRT) repairs were classified as healed. Meniscal extrusion decreased in LMPRTs from of 2.3 ± 1.5 mm to 1.4 ± 1.09 mm (p = 0.080) and increased in MMPRTs from 3.1 ± 1.6 mm to 4.8 ± 1.9 mm (p = 0.005) at FU (between-group difference, p < 0.001). LMPRT repairs were associated with ACL injury and additional meniscal injury and were younger and with lower BMI. No between-group differences were found for KOOS, Lysholm or GRoC Function scores. Tegner scale was higher and GRoC Pain score lower in the LMPRT group compared to the MMPRTs. Conclusion Following transtibial repair for meniscal posterior root repairs, the LMPRTs had a higher frequency of healing, whereas most MMPRTs continued to extrude, despite surgical intervention. The study confirmed that LMPRTs and MMPRTs differ in demography and associated injuries.

Root Repair

Objectives: The medial and lateral menisci function to optimize force transmission across the knee by increasing contact area between the femur and tibia, absorbing shock, and transmitting loads. The anterior and posterior meniscus roots anchor the meniscus to bone. Injuries to the meniscus root attachments result in extrusion of the meniscus, impaired distribution of hoop stresses, and progressive degenerative articular wear. As a result of these deleterious effects, there has been increasing emphasis on repair of meniscus root injuries to restore structure and function. The purpose of this study is to describe meniscus root tears, associated injuries, and minimum 2-year treatment outcomes in a series of pediatric patients. Methods: A single-institution, IRB approved, retrospective review was performed of consecutive pediatric patients less than 19 years of age with a meniscus root tear treated with transosseous root repair over a 4-year period. All patients had minimum 24-month clinical follow-up. Partial root tears treated with partial meniscectomy or irreparable root tears were excluded. All meniscus root tears were classified arthroscopically based on the tear types described by LaPradeADDIN EN.CITE 9. The primary outcomes were revision meniscus surgery and patient reported outcome scores (PROs) (Lysholm, Patient Satisfaction, and Tegner activity). Results: Twenty-one patients, 11 males and 10 females with a mean age of 15 years (range 7 – 18 years), met inclusion criteria. There were 15 lateral meniscus root tears and 6 medial meniscus root tears. The tears occurred in the posterior root in 20 patients (95%). The most common injury pattern was a lateral meniscus posterior root tear (14 patients, 67%). 18 patients (86%) had an associated ligament tear: 13 ACL tears and 5 PCL tears. Two root tears occurred in isolation, and both were the posterior root of the medial meniscus. The majority of meniscus root tears (15 patients, 71%) were root avulsions (type 5). Mean follow-up was 42 months (range 25 – 71 months). Three patients had a second surgery on the affected knee. In two patients, one with revision ACL reconstruction and one treated with chondroplasty of the patella, the meniscus root repair was noted to be well healed. A third patient sustained a new injury to the knee 4 years following medial meniscus posterior root repair and underwent partial medial meniscectomy. At final follow-up, PROs were obtained for 17 patients (81%). Mean Lysholm score was 91 (range 51 – 100). Mean patient satisfaction score was 8.7 (range 5 – 10). Fourteen of 16 patients (88%) reported returning to the same or higher level of activity following surgery. Conclusions: Meniscus root tears occur in pediatric patients, most commonly as root avulsions of the posterior root of the lateral meniscus and in association with ACL tears. This is unique as compared to the adult population, in which the medial meniscus posterior root is often injured in isolation and radial tears adjacent the root are the most commonly described injury pattern. In our case series, transosseous root repair resulted in successful outcomes in the majority of patients with durable results at midterm follow-up.

Abstract Background The best treatment for degenerative medial meniscus posterior root tear (MMPRT) remains controversial. This study aimed to compare the clinical and radiological outcomes of arthroscopic meniscectomy and conservative treatment for degenerative MMPRT. Methods From January 2007 to December 2014, 146 patients (Meniscectomy group, 90; Conservative group, 56) were evaluated. Clinical outcomes were assessed using the Visual Analog Scale, International Knee Documentation Committee subjective scoring scale, Tegner activity scale, and Lysholm knee scoring scale at the final follow-up. Radiologic outcomes evaluated the progression of osteoarthritis (OA) according to the Kellgren-Lawrence (K-L) classification. We compared the hip-knee-ankle angle (HKAA), medial proximal tibial angle, tibial posterior slope angle, and width of medial joint space. After an average follow-up of 6.3 years, the survivorship was analyzed using the Kaplan–Meier method. Results All clinical outcomes were significantly improved in both groups after treatment, with no significant differences between the two groups at the final follow-up. The progression of OA according to the K-L classification, HKAA and width of medial joint space was significantly advanced in the meniscectomy group (p = 0.03, 0.04, 0.03, respectively). The 10-year survival rates in the meniscectomy and conservative groups were 87 and 88%, respectively. Conclusions This study demonstrated that both conservative treatment and meniscectomy provided symptomatic relief. However, it was confirmed that OA progression was more severe in the meniscectomy. We conclude that arthroscopic meniscectomy had no advantage over conservative treatment in terms of clinical outcomes and OA progression in middle-aged patients with MMPRT. Level of evidence Level III; retrospective comparative study.
