Surgical Techniques and Outcomes of Repairing Meniscal Radial Tears: A Systematic Review

August 10, 2022 –

Study Purpose

This study involved a review of medical literature to learn about patient outcomes after surgeries to repair radial meniscus tears. meniscus is repaired versus partially removed.


The researchers reviewed articles about patient studies that met the following criteria:

  • Published between 1980 and 2014
  • Patients were followed up for at least 24 months after surgery
  • Included data on patient outcomes after radial meniscal repair


After their repairs, patients in these studies completed a medical survey called the Lysholm Scale that asked them to rate different aspects of their knee health including pain, instability, locking, swelling, limp, ability to climb stairs, ability to squat, and needing support to move. Based on their responses, each patient was given a score of 0 to 100, with higher scores indicating better knee function with fewer symptoms. During follow-up, each patient provided their Tegner Activity scores, a grade that indicates their ability to be active after their repair.


The researchers looked at short-term outcomes, with average time of follow-ups between 24 and 71 months after surgery.

Main Findings

  • There were six patient studies included in this review
  • Average Lysholm scores after surgery ranged from 86.9 to 95.6 out of 100 across all studies, indication very good knee function
  • Average Tegner activity scores after surgery ranged from 1 (fairly sedentary) to 6.7 (plays recreation or competitive sports several times a week)
  • Outcomes were very similar across all different surgical techniques used to repair the meniscal tears.

Key Message

This study shows that patients who have radial meniscal repairs have very good short-term outcomes.


Save your meniscus to prevent future surgeries and health issues by repairing it with the FDA approved NovoStitch Pro Meniscal Repair System invented by Dr. Saliman.

Meet the awarded surgeon and entrepreneur with the most advanced Meniscal Repair Treatment

Dr. Justin Saliman, a seasoned knee orthopedic surgeon, invented the Edison Award winning “Novo Stitch Pro Meniscal Repair System” to arthroscopically sew back all meniscus tear types – including those previously considered difficult or impossible to sew.


Minimally-invasive, the system involves a “Circumferential Stitching Technique” that has proven superior to traditional meniscus repair techniques. As a result, patients heal pain and dysfunction while preventing arthritis and knee surgical replacement in the long-term.
