Scientific research related to knee arthroplasties shows, depending on the study, that twenty to thirty percent of patients are dissatisfied with the results one year after the operation. Pain, mobility limitations, limited flexion and extension of the knee joint or instability are the main reasons. The shape of each knee joint is more individual than previously thought. Traditional implants force the surgeon to fit the knee to the prosthesis. With an individualised solution the implant is fitted to the knee. Under certain circumstances personalised, individually made implants have significant advantages for you as a patient.
