Improved healing and functional outcome is seen at 12 months after injecting leukocyte rich-PRP in arthroscopically...

A study with the hypothesis: platelet-rich plasma (PRP) injection into labrum repair will produce better healing response and improved functional outcome in patients of recurrent shoulder dislocation treated with arthroscopic Bankart repair.

Arthroscopically repaired recurrent shoulder dislocation patients. Group 1 (cases): administered LR-PRP injection. Group 2 (controls): not received PRP injection. The injection was given arthroscopically at the labrum-bone interface after repair was completed.

A total of 40 patients: 20 in group I (cases) and 20 in group II (controls). The mean age was 26 ± 6 years; 36 patients (90%) were male and 4 patients (10%) were female. All three scores showed improvement at follow-up evaluation inside the groups (P < .001). Individual score improvement was more in group I, the difference was statistically significant for the American Shoulder and Elbow Surgeon (ASES) and Disabilities of the Arm, Shoulder and Hand (DASH) scores (P < .05). The CSS was also higher in group I (93.2 ± 2.8) at follow-up as compared to group II (91.5 ± 2.7, P = .063). Follow-up magnetic resonance imaging (MRI) evaluation showed improvement in labral height (P < .05), Labrum height glenoid index (P > .05), and Labral slope (P < .05) in both the groups, the increase was more in group I as compared to group II.

PRP injection at the labrum-bone interface provides a better healing response in the labrum and better functional outcomes at 12 months after arthroscopic bankart repair.

Level III, case-control study.
