About the trial

What the trial wants to find out

The present study aims to evaluate the long-term and medium-term outcomes of different knee osteotomy techniques in the treatment of knee osteoarthritis in patients with lower limb malalignment. This evaluation is necessary in the current context of research on the treatment and prevention of knee osteoarthritis through treatments that do not involve or allow for the postponement of prosthetic replacement. Among the biological treatments performed in orthopedic clinical practice, osteotomy is one of the most promising. However, further long-term evaluations are needed to more clearly determine the indications and potential of this type of intervention, considering the various surgical procedures described for performing it.

The 2 groups in the trial

  • Closing wedge

    Treatment: High tibial osteotomy

  • Opening wedge

    Patients undergoing opening wedge high tibial osteotomy in knee ostheoarthritis and lower limb malalignement

    Treatment: High tibial osteotomy

Questions to ask the study team

  1. How often do I need to come in, and for how long each time?
  2. Are travel costs paid?
  3. Can I keep my own doctor?
