Ding Y, Liu B, Qiao H, et al. - A prospective pilot study was performed in preoperative (preop) and postoperative (postop) phases on 22 consecutive individuals with knee flexion contracture (KFC) and 12 control individuals who consented to take part from between August 1, 2018, to February 28, 2019, to discover whether KFC could influence cervical alignment and its potential impacts on the posterior muscles and neck tension (NT). KFC could cause spine inclination and craniocervical malalignment, resulting in NT and range of motion decrease. The outcomes of this pilot study may be beneficial in guiding additional studies regarding KFC and NT.
