About

Purushotam Kumar is a rising orthopaedic surgeon-scientist whose research centers on the precision and outcomes of robotic‑assisted arthroplasty, with a particular focus on complex hip and knee deformities. His work has pioneered the application of robotic‑arm‑assisted total knee arthroplasty (RATKA) for moderate to high‑grade valgus knee deformity, providing the first detailed technique and outcomes data for this challenging patient population. In the hip domain, Kumar conducted a landmark CT‑based evaluation demonstrating that robotic‑assisted total hip arthroplasty achieves acetabular cup positioning accuracy comparable to conventional methods, offering critical evidence for the technology’s reliability. His most cited paper (6 citations) on valgus knee RATKA and his subsequent work on cup positioning (4 citations) have already informed surgical decision‑making and training protocols. Kumar’s contributions are notable for bridging the gap between emerging robotic technologies and real‑world surgical challenges, establishing benchmarks for deformity‑specific applications. As robotic arthroplasty continues to expand, his evidence‑based approach positions him as a key voice in defining best practices for precision joint replacement.
