[Knee joint distraction: a solution for young patients with osteoarthritis of the knee?]
The current treatment for patients with end-stage generalised osteoarthritis of the knee is total knee replacement. In a recent paper in Plos One the authors examined an alternative approach, namely knee joint distraction. On the basis of a model, they claim that this treatment can postpone total knee replacement for about 20 years. This would reduce the costs for the healthcare services and improve quality of life for these patients. Although these claims seem promising, the model is only based on extrapolations of short-term results of small cohort studies. Furthermore, concerns about potential complications, e.g. osteomyelitis following pin-tract infections, are not mentioned. Further high quality studies in knee joint distraction are needed to prove its long-term efficacy and safety before this procedure can be implemented in standard clinical care.
