Chang JS, Kayani B, Wallace C, et al. - This study was undertaken to investigate the impact of total knee arthroplasty (TKA) with functional alignment on mediolateral soft tissue balance as evaluated using intraoperative sensor-guided technology. Researchers conducted a prospective study including a total of 30 consecutive patients who had undergone robotic-assisted TKA using the Stryker PS Triathlon implant with functional alignment. They evaluated intraoperative soft tissue balance by applying sensor-guided technology after definitive component implantation; soft tissue balance was defined as intercompartmental pressure difference of < 15 psi. The data exhibited that TKA using the functional alignment achieves balanced mediolateral soft tissue tension through the arc of knee flexion as assessed using intraoperative pressure-sensor technology. Future studies are needed to ascertain whether TKA with functional alignment translates to improvements in patient satisfaction and outcomes compared to conventional alignment techniques.
