Left untreated, meniscal root tears have been reported to result in altered joint biomechanics, accelerated articular cartilage degeneration and an increased risk of developing osteoarthritis (OA) in later life.¹
Furthermore, the use of meniscectomy to treat meniscal root avulsions can lead to significant joint space narrowing within five years.*²

Compared to meniscectomy and/or non-surgical treatment, meniscal root tear repair has been shown in systematic literature reviews and meta analyses to result in:

• Reduced risk of OA: Meta-analyses of medial meniscus posterior root (MMPR) repair have shown that repair leads to significantly lower rates of radiographic OA at 5-year follow-up compared to meniscectomy,**³ and the lowest rate of OA progression (53%) compared to non-operative management (95%) and meniscectomy (99%)⁴
• Lower risk of total knee replacement: MMPRs treated with surgical repair were shown to result in less cartilage degeneration and a 77% reduction in the risk of total knee arthroplasty (TKA).***⁵ In the meta-analysis of 10-year outcomes, MMPR repair resulted in the lowest rate of progression to TKA (34%) when compared to non-operative management (46%) and meniscectomy (52%)⁴
• Improved patient-reported outcome scores: When analysing the mean differences between pre- and post-operative scores, a meta-analysis showed improvements in post-operative Lysholm, HSS, IKDC, KOOS and VAS scores⁶
