What is the best option for young, active patients with knee arthritis?

It is with great interest that we reviewed the recent research publication by Krych et al., Unicompartmental Knee Arthroplasty Provides Higher Activity and Durability Than Valgus-Producing Proximal Tibial Osteotomy at 5 to 7 Years (1). The authors sought to determine retrospectively whether a valgus producing proximal tibial osteotomy (PTO) or a medial unicompartmental knee arthroplasty (UKA) offered younger, more active patients the best post-operative outcomes with respect to activity level, function, and durability.
