Li Z, et al. - Investigators examined the data to investigate the efficiency of treatment of full-thickness tear of the rotator cuff using the arthroscopic bone marrow stimulation (BMS) technology. They noticed that Constant score of BMS group was significantly higher as compared to the control group at the third follow-up month. Although, they found a decline in the postoperative re-tear rate of the BMS group. They observed no important difference in the postoperative Constant and UCLA score among all groups. Overall, they found no significant impact of BMS technology on the postoperative clinical outcome. But, they preferred it for clinical treatment due to the obvious promotion of tendon-to-bone healing of the rotator cuff and decline in the re-tear rate.
