Why the study?
Patients awaiting TKA often experience strength and functional decline because standard high-resistance exercise is poorly tolerated preoperatively or postoperatively.
Does preoperative blood flow restriction exercise attenuate postoperative loss of physical function in patients undergoing total knee arthroplasty?
Comparison
Preoperative blood flow restriction exercise vs standard of care (no exercise)
Design
Randomized pilot study
Follow-up
2 weeks postoperatively
Key result
Preoperative blood flow restriction exercise was feasible and resulted in less decline in physical function following total knee arthroplasty compared to standard care (SPPB change -2.2 vs -4.8).

Does preoperative blood flow restriction exercise attenuate postoperative loss of physical function in patients undergoing total knee arthroplasty?
Absolute Event Rate: -2.2% vs -4.8%
Preoperative low-resistance exercise using blood flow restriction is feasible and may attenuate postoperative loss of physical function after total knee arthroplasty.
Przkora et al. (2021) conducted an RCT in Osteoarthritis requiring total knee arthroplasty (n=10). Blood flow restriction (BFR) exercise vs. Standard of care (no exercise) was evaluated on Change in Short Physical Performance Battery (SPPB) score at 2 weeks postoperatively. Preoperative blood flow restriction exercise was feasible and resulted in less decline in physical function following total knee arthroplasty compared to standard care (SPPB change -2.2 vs -4.8).
