Brief summary
This project is intended to acquire objective measurements of implementing BFR rehabilitation in ACL reconstructions to show any changes upon completion of the BFR protocol. The results in this study will hopefully represent valuable data in the support of using autografts for ACL reconstructions in high level athletes wanting a full recovery and return to high level of sport. It has been speculated that use of autografts in ACL reconstructions leads to more quad weakness and muscle atrophy due to tendon harvesting. (Slone et al., 2015) More recently, BFR has shown promise in expediting the recovery and rehabilitation process post-surgically. By implementing BFR following ACL reconstructions with autografts, we hope to mitigate the major deterrent for autograft use and giving patients a more cost-effective approach to surgery. (Hughes et al., 2019)
Detailed description
Specific Aim 1 will identify the overall preservation of muscle and changes in body composition after injury and throughout surgical rehabilitation in athletes undergoing ACL reconstruction. It is hypothesized that implementing BFR rehabilitation protocols following ACL reconstruction with autografts will expedite recovery and return to sport and rescue of muscle tissue at the donor site. Specific Aim 2 will monitor muscle strength and activation following ACL reconstruction with performance of standardized assessments at intervals. It is hypothesized that BFR implementation will show greater return to strength and enhanced muscle activation during testing.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Quad muscle Strength | At 6 week post surgical timepoints | Compare the muscle strength gain or loss between BFR group and control group |
