About this study

Rationale: Realignment osteotomies around the knee are a proven surgical treatment for unicompartmental knee osteoarthritis and a malalignment. Osteotomies can be very painful in the early postoperative phase. This is probably due to a combination of bony cut (bone pain) and postoperative hematoma (bleeding and leakage of the bone marrow) in the surrounding soft tissue. The AttraX® Putty can be used as a gap filler in open wedge osteotomies to potentially reduce postoperative pain by reducing the bleeding from the bone gap. Objective: The main aim of this study is to determine whether early postoperative pain is decreased when the osteotomy gap is filled with AttraX® Putty, compared to conventional open wedge osteotomy without filling the gap. The secondary aims are faster accelerated rehabilitation/regaining function, reduction of local blood loss, accelerated bone union, comparable surgical accuracy, and the occurrence of (serious) adverse events. Study design: Single-blinded, prospective, randomized controlled trial. Study population: Adult patients qualifying for open-wedge tibial, open-wedge femur or double level osteotomy. Intervention: According to a randomization scheme, the osteotomy gap will be filled with either the synthetic ceramic material AttraX® Putty or without a gap filler (conventional method). Main study parameters/endpoints: The main study endpoint is the Numeric Rating Scale (NRS) pain during the first week postoperative. The secondary study endpoin…
