Repair of Radial Meniscus Tears Results in Improved Patient-Reported Outcome Scores: A Systematic Review.


ABSTRACT:

Purpose

To quantify healing rates and patient-reported outcome scores following repair of radial meniscus tears.

Methods

PubMed, Scopus, and Embase databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Inclusion criteria included: human subjects with meniscal tears, full-text English language, average follow-up of at 1 year, and publication after the 2000. Exclusion criteria included technical, biomechanical, and cadaveric studies. Study quality was assessed using Coleman Methodology Scores and Methodological Index for Non-Randomized Studies (MINORS) criteria.

Results

Twelve studies reported on the repair of 243 radial tears in 241 patients. The mean Modified Coleman Methodology Score was 46.8, range 26-60, with a mean level of evidence of 3.5. Arthroscopic techniques were used in all studies, with 1 study using an arthroscopic-assisted 2-tunnel trans-tibial pullout technique. The mean patient age was 32 years (11-71). The mean follow-up was 35 months (12 to 75.6). The average time to surgery was 10.9 months (0.5-22.4). Eight of the 12 studies reported concomitant anterior cruciate ligament (ACL) reconstruction, with 64% having concomitant ACL injury. The most common outcome measure was the Lysholm score, which improved from 47-68.9 preoperatively to 86.4-95.6 postoperatively. Tegner Activity Scale improved from 2.5-3.1 preoperatively to 4.7-6.7 postoperatively. Healing rates were reported via magnetic resonance imaging and second-look arthroscopy. Second-look arthroscopy was performed for a variety of indications, including removal of screw, washers or plates, dissatisfaction with original procedure, partial healing found on magnetic resonance imaging, or desire of the patient to know the true healing status before return to sport. Of those assessed, 62.0% had complete healing, 30.0% partial healing, and 8.0% failure to heal.

Conclusions

Patient-reported outcomes of radial meniscus repair with and without ACL reconstruction are encouraging, with high patient-reported outcomes reported at final follow-up when compared with preoperative scores. Among all meniscus repairs assessed for healing, the majority demonstrated at least some healing with an overall low rate of failure.

Level of evidence

IV; systematic review of level III-IV studies.
