This study investigated the effect of tourniquet use on early recovery after total knee arthroplasty (TKA) using a smartphone app-based patient engagement platform (PEP) with a wrist-based activity monitor. The results showed that tourniquet use did not have a clinically significant negative impact on pain and function in the first 90 days after surgery.
Background: The impact of tourniquet use on recovery after total knee arthroplasty (TKA) remains controversial. The purpose of this prospective, single blinded, randomized controlled trial was to investigate the effect of tourniquet use on early recovery after TKA using a smartphone app-based patient engagement platform (PEP) with a wrist-based activity monitor to obtain more robust data on early recovery. Methods: There were 107 patients undergoing primary TKA for osteoarthritis who were enrolled (54 tourniquet [TQ+]; 53 no tourniquet [TQ-]). All patients utilized a PEP and wrist-based activity sensor for 2 weeks preoperatively and 90 days postoperatively to collect Visual Analog Scale (VAS) pain scores and opioid consumption, as well as weekly Oxford Knee Score (OKS) and monthly Forgotten Joint Score (FJS). There was no difference in demographics between groups. Formal physical therapy assessments were performed preoperatively and 3 months postoperatively. Independent sample t-tests were used for continuous data and Chi-square and Fisher's exact tests were used for discrete data. Results: Tourniquet use did not have a statistically significant impact on daily VAS pain or opioid consumption during the first 30 days postoperatively (P > .05). Tourniquet use did not have a significant impact on OKS or FJS at 30 or 90 days postoperatively (P > .05), or on performance of formal physical therapy testing at 3 months postoperatively (P >.05). Conclusion: Using a digital technology to collect daily patient data, we found that tourniquet use has no clinically significant negative impact on pain and function in the first 90 days after primary TKA.
