Title: Experimental Model of Medial Meniscus Posterior Root Tear Increases the Severity of Cartilage Damage in Rabbits
Abstract: similar cartilage regeneration (31.3% to 41.7%).In consistency with previous studies, the integrity of MMPR played a minor role in cartilage regeneration.This leads to the interpretation that healing rate and cartilage regeneration are not correlated with clinical outcome scoring.[Discussion] An HTO could unload the pressure in the medial compartment, thus relieving varus-induced medial knee pain.According to previous studies, HTO alone without MMPR repair achieved favorable outcomes.Lee et al. and Ke et al. also described similar findings in their cohort studies.The beneficial effects of concurrent MMPR repair during HTOs increase the rate of meniscal healing.However, long-term follow-up should still be conducted in order to further investigate whether the repair technique could help provide longer survivorship of the HTOs.[Conclusions] Concurrent MMPR repair during HTOs presented with a better MMPR healing rate but similar cartilage regeneration rate in short-term to mid-term follow-up.However, a better healing rate was not associated with higher clinical scores.For deeper and more extensive conclusions to be drawn, follow-up should be continued longterm.
