Grabbin, TX — Use of a smartphone-based care platform after partial or total knee arthroplasty had similar 1-year clinical outcomes as standard of care and lower use of health care resources.
David A. CrawfordMD, and colleagues randomized patients with either partial or TKA to undergo either a smartphone-based care management program (n = 160) or a standard of care (n = 241) after surgery.
“The outcomes we evaluated were uses of healthcare resources, such as physical therapy, readmission, ED, or urgent care visits. [and] Non-standard care office visits, with clinical findings manipulated under anesthesia, [Knee Injury and Osteoarthritis Outcome Score for Joint Replacement] KOOS JR, [EuroQol-5D] EQ-5D and back to activities in 3 months,” Crawford said in his presentation at the annual meeting of the American Association of Hip and Knee Surgeons.

Looking at the partial knee and TKA groups combined, Crawford noted that patients in the treatment group used significantly less physical therapy and had a significantly lower rate of ED visits during the first year. The results showed that both groups had similar scores for KOOS JR and EQ-5D at a one-year follow-up.
At a 6-month follow-up, patients who crossed over to the control group had significantly lower scores on the KOOS JR, according to Crawford.
“In the first year, patients who did well with the app and didn’t crossovers did better than the control group,” Crawford said.
Overall, Crawford noted that 65% of patients who underwent TKA and 46% of patients who underwent partial knee arthroplasty used physical therapy after surgery compared to 94.8% and 94% of patients in the control groups, respectively.
Then finally, back to activities. This was the percentage of patients who returned to activities for 3 months and the number of days it took them to get there,” Crawford said. “The only significant finding is, in the treatment group, that it took fewer days to encourage walking without an assistive device. Nothing else was significantly different.”
