Surgical procedure

  • KneeRiviver is placed on eight bone pins, drilled into the femur and tibia.
  • By placing the KneeRiviver, the distractor at the same time functions as your guide. It will easily tell you where to place the next pin.
  • Pins are placed extra-articular,
    which leaves the joint undisturbed. 
  • After a short learning-curve the procedure will approximately take 30-45 minutes.
  • After placement directly 2 mm of distraction is applied. The next 3 mm is gradually given in the next days.

Rehabilitation

  • After knee joint distraction, the preservation of the knee joint ensures that all forms of treatment are still possible, if needed.

What does the KneeReviver do?

The KneeReviver unloads the damaged knee joint by putting the knee joint surfaces on a short distance. Advantages of knee joint distraction treatment:

  • Knee joint distraction is a joint preserving treatment.
  • Patients receiving a knee prosthesis under the age of 65 years have an increased risk of failure of this prosthesis.
  • Postponing a knee prosthesis will eventually avoid revision surgery.
  • All other treatment options are still possible when complaints eventually recur.
