Background summary
Recently, patient-specific guiding (PSG) was introduced in total knee arthroplasty (TKA) and UKA. It is believed but not yet proven that this technique aids in improvement of prosthesis position but also in decreasing operation time
and decreasing blood loss. However, limited literature is present on PSG in UKA
Study objective
We hypothesize that there is no difference in clinical and radiological outcome when using PSG for UKA compared with results from the literature describing results from conventional UKA surgical techniques.
Study design
preoperative and follow-up at 3 months, 1 and 2-years
Intervention
A relatively new technique for the perioperative alignment of prosthesis components inunicompartmental knee arthroplasty (UKA) is the use of patient-specific guiding (PSG). The guides used in this technique are made of synthetic material, custom-made using MR imaging to fit anatomical landmarks of femur and tibia of a certain patient. These guides assist the surgeon in placing the implant in an anatomic fashion. Precision in implant placement restores biomechanics of the knee joint and should increase longevity of the prosthesis
