Abstract:
Medial open-wedge (MOW) high tibial osteotomy (HTO) is proven treatment option, indicated in medial unicompartimental knee osteoarthritis (OA) and in varus OA. New devices and techniques were developed in last years, such as Activemotion plates with polyaxial locking system (Dualtec System®, NewClip-Technics) and PSI technique. We describe outcomes and rate of complications in patients treated with Activemotion plates and PSI technique. From January 2019 to August 2019 a sample of 77 cases (72 NCT plates, 5 PSI technique) was observed, evaluating the rate of complications and the return to activity. The rate of complications is 2.6% and the mean time to return to activity is 10 weeks. MOW HTO with Activemotion plate has showed good results with a low rate of complications. About PSI technique, the preliminary results are excellent, but we need to increase the sample.
