Surgical technique: Skin incision medial of the tibial tuberosity approximately 8-10 cm. Insertion of two converging guidewires directly above the pes anserinus, ascending obliquely, and ending at the tip of the fibula. Control of the wire position with the image intensifier. Osteotomy with an oscillating saw. Removal of the wedge and closure of the osteotomy. Osteosynthesis with a medial angle-stable plate.
Postoperative management: Partial load bearing with 10-20 kg for 2 weeks, then step-wise increase in load. Mobility: free.
Results: We performed this surgery in the manner described in 21 patients with lateral osteoarthritis or cartilage damage (17 men, 4 women, average age: 51 years). The valgus deformity was reduced from an average of 5.6 to -0.5°. The KOOS-PS (Knee Injury and Osteoarthritis Outcome Score-Physical Function Short-form) score decreased significantly from 39.1 ± 14 to 25.8 ± 20 points.
期刊介绍：
Orthopedics and Traumatology is directed toward all orthopedic surgeons, trauma-tologists, hand surgeons, specialists in sports injuries, orthopedics and rheumatology as well as gene-al surgeons who require access to reliable information on current operative methods to ensure the quality of patient advice, preoperative planning, and postoperative care.
The journal presents established and new operative procedures in uniformly structured and extensively illustrated contributions. All aspects are presented step-by-step from indications, contraindications, patient education, and preparation of the operation right through to postoperative care. The advantages and disadvantages, possible complications, deficiencies and risks of the methods as well as significant results with their evaluation criteria are discussed. To allow the reader to assess the outcome, results are detailed and based on internationally recognized scoring systems.
Orthopedics and Traumatology facilitates effective advancement and further education for all those active in both special and conservative fields of orthopedics, traumatology, and general surgery, offers sup-port for therapeutic decision-making, and provides – more than 30 years after its first publication – constantly expanding and up-to-date teaching on operative techniques.
