Video Summary

In this video, Jordan Lyles from the Arizona Sports Medicine Center discusses a study on how different osteotomies affect compartment pressures in the knee during flexion. The study aimed to determine the effects of osteotomy location on compartment pressures and contact areas in the knee. Through experiments on cadavers, it was found that high tibial osteotomy (HTO) effectively reduced lateral compartment pressure at various degrees of flexion, while distal femoral osteotomy (DFO) showed a return to near-native pressure levels as flexion increased. HTO also transferred pressure to the medial compartment at higher flexion angles. It is important to carefully assess the patient's anatomy and factors when deciding between HTO and DFO. The research team at UConn contributed to prior knowledge on this topic. Credits were given to Dr. Vidal, Dr. Budall, and the Stedman Clinic.
