Unicompartmental Knee Arthroplasty vs. High Tibial Osteotomy for Medial Knee Osteoarthritis (UNIKORN): a Study Protocol of a Randomized Controlled Trial (UNIKORN)

July 1, 2022 updated by: Juuso Siren, Töölö Hospital
Unicompartmental knee arthroplasty (UKA) and High Tibial Osteotomy are both valid treatment options for isolated medial knee osteoarthritis. Literature to date is lacking high grade evidence of the outcomes between these procedures. This is a study protocol for randomized controlled trial comparing UKA vs HTO in late stage medial knee osteoarthritis.
