Video Summary

Chris Travers from the University of Pennsylvania discusses unicompartmental knee arthroplasty (UNI) versus high tibial osteotomy (HTO) for isolated compartmental osteoarthritis. While both address similar indications, UNI resurfaces the damaged compartment maintaining mechanical axis, whereas HTO shifts the axis to offload the compartment. Indications overlap, but contraindications for UNI are evolving. Long-term data show 94% survivorship at 12 years for UNI in younger patients, with low limitations in sports. Meta-analyses reveal lower revision rates and complications with UNI, though HTO offers slightly better range of motion. Trends favor increasing UNI usage due to faster recovery, easier technique, and improved implants, suggesting UNI will become more dominant.
