Effect of Outpatient Rehabilitation on Functional Mobility After Single Total Knee Arthroplasty: A Randomized Clinical Trial.

Importance: Even without evidence, rehabilitation practitioners continue to introduce new interventions to enhance the mobility outcomes for the increasing population with a recent total knee arthroplasty (TKA).

Objective: To compare post-TKA functional mobility outcomes among 3 newly developed physical therapy protocols with a standard-of-care post-TKA rehabilitation protocol.

Design, Setting, And Participants: This randomized clinical trial included 4 study arms implemented in 15 outpatient clinics within a single health system in the Baltimore, Maryland, and Washington, District of Columbia, region from October 2013 to April 2017.

Innovative Devices Did Not Provide Superior Total Knee Arthroplasty Outcomes in Post-Operative Rehabilitation: Results From a Four-Arm Randomized Clinical Trial.

Background: Orthopedic surgeons face an increasing array of post-TKA (total knee arthroplasty) rehabilitation interventions that entail innovative equipment and devices, but their relative effectiveness remains unknown. The study compared patient outcomes among primary unilateral TKA patients participating in one of 4 post-TKA rehabilitation interventions-a standard-of-care intervention and 3 more recently developed physical therapy interventions.

Methods: The Knee Arthroplasty Rehabilitation Outcomes Study is a 4-arm randomized clinical trial conducted across 15 outpatient rehabilitation clinics.
