Abstract:
Cases of valgus knee deformity are relatively rare and special cases in the orthopedic clinics. Especially severe deformities according to Keblish classification are challenging cases for orthopedic surgeons. These patients require a serious preoperative planning prior to surgery. Herein, we shared a our case with a 67-year-old woman with 45° valgus knee deformity with congenital hip dislocation on the right lower limb, which was classified as a severe deformity according to Keblish classification. Knee examination revealed 60° flexion and almost complete extension of right knee. As a result of our planning, we decided to use a Rotating Hinge Knee (RHK) prosthesis to maintain bone and soft tissue balance. The NexGen RHK prosthesis was preferred to correct deformity. Fracture of the medial femoral condyle occurred and fixed as intraoperative complication. The Knee Society Score (KSS) increased from 40 to 91. Patient stated that knee pain completely resolved and could be mobilized easily. RHK prosthesis is an important option for correction deformity in patients with severe valgus knee deformity. Long-term follow-up of these patients is needed to determine the success rate.
