Study designNon-randomised, non-controlled, interventional clinical trial
Secondary study designSingle-centre
Scientific titleJoint distraction in the treatment of knee osteoarthritis: efficacy and underlying mechanisms
Study objectivesJoint distraction is a relatively new approach in the treatment of severe Osteoarthritis (OA). Clinical efficacy has been proven for hip and ankle OA.

Hypothesis:
A two month distraction period results in similar clinical beneficial effects as a three month distraction period.
Ethics approval(s)Approval received from the Medical Ethical Committee of the University Medical Centre Utrecht on the 28th July 2004.
Health condition(s) or problem(s) studiedOsteoarthritis
InterventionJoint distraction applies temporary (two months) relief of mechanical wear and tear of the articular cartilage surfaces forming a joint. Nutrition of the cartilage is maintained due to intra-articular fluid pressure changes during treatment. Additionally subchondral sclerosis is diminished, diminishing mechanical stresses on the cartilage after treatment.
Intervention typeOther
Primary outcome measure(s)

Pain (according to the The Western Ontario and McMaster Universities Osteoarthritis Index [WOMAC])

Key secondary outcome measure(s)

Functional disability (according to the WOMAC)
