A meta-analysis by Zhang et al. (2018) compared the clinical outcomes of single-row versus double-row rotator cuff repair. The study found no significant difference in functional outcomes between the two techniques, suggesting that the choice of technique should be based on factors such as tear size and surgeon experience.
Another randomized controlled trial by Park et al. (2018) investigated the effects of platelet-rich plasma (PRP) on rotator cuff healing. The study found that while PRP reduced retear rates, it was not cost-effective.
