Abstract
Objective: To treat instability caused by a genu recurvatum using ventral open wedge osteotomy of the distal femur.
Indications: Knee instability caused by Genu recurvatum with femoral extension deformity.
Contraindications: Inadequate blood flow to the lower extremity, soft tissue issues, obesity, osteoporosis.
Surgical technique: Through a primary medial approach to the distal femur, a ventral open wedge osteotomy is performed using chisel bunch formation and arthrodesis spreader. For symmetrical expansion, another lateral approach at the distal femur and insertion of another arthrodesis spreader is performed. Osteosynthesis was performed with an angle stable plate from the medial side and with additional stabilization using a 4-hole angle stable plate from the lateral side. The osteotomy gap was filled with a bone graft wedge.
Postoperative management: Partial weight-bearing of 20 kg was allowed for 6 weeks with passive exercise and lymphatic drainage. A hard frame orthosis for immobilization at 0-10-90° was fitted for 6 weeks. Radiographic controls were performed at 6 weeks, 3 months, and 1 year. After the last radiographic control, hardware was removed.
Results: There are no reports in the current literature regarding the effect of a change in the sagittal plane at the distal femur on alignment, stability, and biomechanics of the knee. This case report shows that genu recurvatum with physiological posterior tibial slope can be successfully treated with anterior femoral flexion osteotomy. Hyperextension was completely eliminated at the follow-up examination after hardware removal after 12 months.
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.
