Swelling Management After Total Knee Arthroplasty: A Randomized Controlled Trial
University of Colorado, Denver
Summary
To determine if inelastic adjustable compression garment results in improved surgical limb swelling control (bioimpedance assessment - primary outcome) after TKA compared to control (TED hose).
Description
Total knee arthroplasty (TKA) is commonly performed to address disability from end-stage osteoarthritis (OA) in older adults and is expected to increase five-fold by 2040 to 3.5 million TKAs annually. Although TKA is effective at reducing pain, it is a substantial acute trauma to the joint that exacerbates the underlying weakness and disability common with OA, leading to long-term atrophy and further disability. Attenuation of this acute loss of strength and function leads to improved long-term outcomes. Key to preventing this acute loss is effectively managing postoperative knee swelling. Kn…

Interventions
- OtherInelastic adjustable compression garment (INCOM)
Immediately following surgery, participants randomized to INCOM will wear an inelastic adjustable compression garment set to a minimum of 30mm Hg of compression utilizing a standardized garment tensioning tool. Participants will be instructed to wear the compression garment during waking hours with a target wear time of 80% of waking hours. Participants will participate in a standardized rehabilitation program
- OtherElastic compression garment (CONTROL)
Immediately following surgery, participants randomized to CONTROL will wear a thigh-length elastic compression garment (thromboembolism-deterrent \[TED\] hose) for the first 3 weeks after TKA. Participants will be instructed to wear the compression garment during waking hours with a target wear time of 80% of waking hours. Participants will participate in a standardized rehabilitation program
