The purpose of rehabilitation is to help patients to recover their daily ability and increase wellbeing. All knee injuries are treated as active rehabilitation, which is performed by physiotherapists or doctors. The aim of rehabilitation for the knee joint is to allow the patient to move freely without pain, after a trauma or post-surgery. MAKNEE provides support for rehabilitation monitoring, enhancing the progress of rehabilitation by assessing the changes within the joint periodically. Eventually, our device can confirm the efficacy of the rehabilitation treatment, or at the contrary suggest some revision in case of unsatisfying results.
