13 Orthobiologics in Athletic Medicine Hamstring strains Tendon Tendinopathy Repair Ligament MCL ACL repair/reconstruction tear Meniscus repair Cartilage Repair Protect Facilitate performance

14 BURDEN HAMSTRING STRAIN BASEBALL, SOCCER MLB $ 29 million per year MLS $ 7 million per year

15 Five randomized controlled trials including a total of 268 patients with grade I and II acute HS injury NO Difference with PRP for RTP

16 CLINICAL EVIDENCE Achilles Tendon 24 Studies PRP vs Saline (x2) PRP vs Rehabilitation Program No Significant difference between groups Acute Achilles Repair + PRP No difference - Detrimental?

17 CLINICAL EVIDENCE Patellar Tendon Multiple Injections ( Zayni -Yes / Kaux - No) Significant Improvement PRP vs ESWT PRP better than DN at 12 wks but not at 26wks 19 Studies One vs Multiple Injections(x2) PRP vs Shockwave Therapy PRP vs Dry Needling After ACLR - BTB Better Pain Control Better Healing at 6 mo

18 Video Analysis of Anterior Cruciate Ligament Injuries in the National Football League D Schub; R Brophy; T Wuerz; B Cole; T McAdams; H Silvers; N Elattrache; S Rodeo; B Mandelbaum

19 Show more Genomics Gene variants within the COL1A1 gene associated with reduced ACL injury in professional soccer players Cieszczyk et al male professional soccer players with surgically diagnosed primary ACL ruptures. control group consisted of 143 apparently healthy male professional soccer players Conclusions Frequency of COL1A1 G-T haplotype is associated with reduced risk of ACL injury

20 ACLR MRI Graft Maturation Radice et al Santiago Prospective single-blinded study 50 pts w/ ACLR 25 pts w/ PRP plasma gel 25 pts w/o MRI performed between 3 and 12 months post-op Looking for homogenicity in the graft = healed Mean time to complete homogenicity 177days vs 369 days 48% reduction in healing

21 ACLR and PRP Systemic Review Murray et al Graft Maturation 7 studies significantly better outcomes in the platelet groups in 4, and there were large differences in means in an additional 2 studies. Donor site 2 studies show less pain and less gap Tunnel Healing 5 studies 4 found no difference between groups. 1 showed improved early healing Clinical Outcome 3 studies found no differences, regardless of whether they had shown a beneficial effect (1 of 3) or no effect (2 of 3) of platelets on graft and tunnel healing.

22 animal studies were included 6/7 studies BMSCs improved histology, biomechanics, and biochemistry at 12 w 4 studies using ACL-derived vascular stem cells improved a histology, biomechanics, and imaging within 8 weeks postoperatively 2 studies tendon-derived stem cells (TDSCs) and human umbilical cord blood derived mesenchymal stem cells (hucb-mscs) improved results In animals BMSCs, ACL derived SCs, TDSCs and UC MSCs ALL have positive effect

23 /43 patients with ACLR with BMAC vs Control MRI no difference Conclusion BMAC injections do not seem to accelerate graft-to-bone healing in ACL reconstruction

24 The Bridge-Enhanced Anterior Cruciate Ligament Repair (BEAR) Procedure An Early Feasibility Cohort Study Murray, Micheli et al 2016 Suture Repair Swivel lock to footprint Bridge TM scaffold over repair Collagen sponge and PRP 10 pts BEAR 10 HS Conclusion: The results of this study suggest that the BEAR procedure may have a rate of adverse reactions low enough to warrant a study of efficacy in a larger group of patients

31 2013 Registry study 17 condyles in 15 patients OCA transplantation without BMC and 29 condyles in 22 patients who underwent OCA transplantation with BMC BMAC group had significantly better graft integration
