BACKGROUND: Despite growing interest in minimally invasive surgery (MIS) techniques for total knee arthroplasty (TKA), few randomized controlled trials have compared MIS and conventional TKA using a combination of functional performance, knee pain, knee range of motion (ROM), and surgical and radiographic outcomes. METHODS: A prospective, randomized investigation comparing early outcomes of TKA using conventional or MIS approaches (n = 44). Patients were assessed preoperatively, 48 hours, 4 and 12 weeks postoperatively by blinded evaluators. Outcome measures included timed-up-and-go, 100-ft walk, knee pain, passive knee ROM, Knee Society Score, blood loss, tourniquet time, hospital length of stay, surgical complications, and radiographic outcomes. RESULTS: No significant differences in functional performance, knee pain, knee ROM, surgical, or radiographic outcomes were observed between groups at 48 hours, 4 or 12 weeks postoperatively. CONCLUSION: While surgical and radiographic outcomes were not compromised with MIS surgery, there were also no improvements in pain, ROM, or functional performance with MIS TKA.
