Summary of included randomized controlled trial
| Authors/publish year | Population differences | Repair type | Outcomes measured | Relevant findings | 
|---|---|---|---|---|
| Castricini et al. 2011 [25] | Included any full-thickness tear | Double row | Subjective: Constant scores Imaging: MRI at 16 months | No difference in constant scores and retear rates between groups | 
| Randelli et al. 2011 [31] | Included any full-thickness tear | Single row | Subjective: Constant, UCLA, SST Imaging: MRI 12 months | Significant improvement in constant, UCLA, and SST in PRPþ group No difference in outcomes at final follow-up | 
| Gumina et al. 2012 [27] | Included only large tears Excluded partial tears, massive tears, traumatic tears | Single row | Subjective: Constant, ST Imaging: MRI at 12 months | Significantly increased constant score in the PRPþ group, but no difference in change from pre- to postoperatively | 
| Weber et al. 2012 [35] | Included any arthroscopic rotator cuff repair | Single row | Subjective: ASES, UCLA, SST, VAS Imaging: MRI at 12 months ROM | No difference in outcome scores or ROM between groups No difference in retear rates between groups | 
| Jo et al. 2013 [28] | Included only large tears (> 3 cm sagittal length) Included 4 partial repairs | Double row | Subjective: ASES, CLA, Constant, SST, DASH, SPADI Imaging: MRI or CTA at 9 months | No difference between the two groups on the VAS for pain, ROM, muscle strength, overall satisfaction, and function The retear rate of the PRP group was significantly lower | 
| Ruiz-Moneo et al. 2013 [33] | Included tendon retraction and fatty infiltration, smokers | Double row | Subjective: UCLA Imaging: MRA at 12 months | No difference in UCLA scores between groups No difference in retear rates between groups | 
| Malavolta et al. 2014 [30] | Included only tears < 3 cm in sagittal length | Single row | Subjective: Constant, UCLA Imaging: MRI at 3, 6, and 12 months | No differences in constant or UCLA scores between groups No difference in retear rates between groups | 
| Sánchez Márquez et al. 2011 [34] | Included only repairable large tears > 5 Excluded subscapularis tears | Single row | Subjective: Constant Imaging: MRA at 12 months | No differences in constant or UCLA scores between groups No difference in retear rates between groups | 
| Rodeo et al. 2012 [32] | Included full-thickness tears, age > 40 years | Double row | Subjective: ASES, L’Insalata Imaging: US at 12 weeks | No difference in outcome scores between groups No difference in retear rates between groups | 
| Flury et al. 2016 [26] | A complete rotator cuff tear | Double row | Subjective: Constant-Murley score, ASES, OSS Imaging: MRI or US at 12 months | No significantly improved function at 3, 6, and 24 months after arthroscopic repair compared with control patients receiving ropivacaine | 
| Holtby et al. 2016 [9] | Full-thickness and partial-thickness tear | Single row and double row | Subjective: VAS, CMS, ASES, ShortWORC Imaging: MRI at 6 months | A short-term effect on perioperative pain No significant impact on patient-oriented outcome measures or retear rate | 
| Pandey et al. 2016 [10] | Medium-sized to large cuff tears | Single row | Subjective: VAS, CMS, ASES, UCLA Imaging: US at 24 months | Retear in the PRP group was significantly lower, significant improvement in constant, UCLA score No difference in ASES score | 
| Jo et al. 2015 [29] | Medium to large rotator cuff tears | Double row | Subjective: Constant score, VAS, ASES, UCLA, SST, SPADI scores Imaging: MRI at 12 months | A decreased retear rate of the supraspinatus, but not the speed of healing No significantly improved function scores at and 12 months after arthroscopic |
