Introduction: This study examined the effects of personalized blood flow restriction (PBFR) on quadriceps girth following a total knee arthroplasty (TKA). Methods: 6 individuals participated (CON: n=3, R: n=3). PBFR paired with light intensity resistance training (LIRT) was administered 4 weeks postoperative for 9-weeks, 2 times per week. Girth measurements at 10cm and 15cm above the knee joint were taken 1, 4, and 12 weeks postoperative for CON and R-groups. The control group participated in traditional physical therapy modalities that did not include BFR. Results: The study found that PBFR training is 87.5% likely beneficial at increasing quadriceps girth at 10cm above the knee joint, and 92.8% likely beneficial at increasing quadriceps girth at 15cm above the knee joint. Conclusion: This study demonstrates that PBFR+LIRT can be an effective modality for increasing quadriceps girth, when used in conjunction with a rehabilitation program following a TKA.
