The effect of perioperative platelet-rich plasma injections on postoperative failure rates following rotator cuff repair: a systematic review with meta-analysis.

Background: Platelet-rich plasma (PRP) has gained significant interest in recent years to potentially add biological augmentation of healing to surgical repairs of soft-tissue injuries. We sought to determine whether perioperative PRP injection influences the risk of failure following rotator cuff repair.

Methods: A systematic search was performed in the Embase and PubMed databases and identified 16 randomized controlled trials or prospective cohort studies (1045 participants) reporting rates of failure, defined as a subsequent tear on postoperative imaging, after rotator cuff repair with or without perioperative PRP administration.

Individual Coping Strategies Are Associated with Patient-Reported Satisfaction upon Completion of Rehabilitation following Sports-Related Knee Surgery.

We sought to determine whether individual coping strategies and optimism are associated with satisfaction after sports-related knee surgery at the time of rehabilitation completion and whether the association between coping strategies/optimism and satisfaction varies by surgical procedure or length of rehabilitation. A total of 104 recreational and competitive athletes who underwent knee surgery completed preoperative assessments for intrinsic optimism using the revised Life Orientation Test and coping strategies using the brief Coping Orientations to the Problem Experience inventory. Postoperative assessments at completion of rehabilitation (mean: 5.
