Midterm Outcomes of Posterior Medial Meniscus Root Tear Repa
The purpose of this study was to report the midterm clinical outcomes from PMMRT repairs.

A literature review for this systematic analysis was performed in accordance with the PRISMA guidelines. Researchers identified studies that reported the results of arthroscopic repair of PMMRTs. Functional and imaging outcomes were reviewed and summarized.

--In total, 28 studies with a total of 994 patients (83% female) with an overall mean age of 57.1 were included in this review.

--Clinical outcomes were improved at final follow-up in all studies.

--Of patients, 49% had radiographic progression of at least 1 grade in the Kellgren-Lawrence scale at a mean follow-up of 4.0 years in 11 studies.

--Cartilage degeneration had progressed at least 1 grade on magnetic resonance imaging scans in 23% of patients at a mean follow-up of 31.6 months in 4 studies.

Finally, PMMRT repairs have been shown to produce a functional benefit as well as consistent improvements in clinical outcome scores. At midterm follow-up, there is some evidence that PMMRT repair slows the progression of osteoarthritis but does not prevent it.
