Abstract

Introduction Knee osteoarthritis with valgus deformity presents a surgical challenge that must be solved during total knee arthroplasty (TKA). In some case whereby ligament imbalance is found, constrained implant should be used. Unfortunately, the implant is not always readily accessible in some developing countries. The objective of this paper is to provide alternative solution to such case. Presentation of case We reported a 71-year-old female patient with a painful and fixed valgus deformity of her right knee. Preoperatively, the patient’s right knee range of motion (ROM) was 10–145° of flexion with a 32° fixed valgus deformity. A constrained implant was not accessible. To balance the ligament, Medial Collateral Ligament (MCL) origin was shifted to superior and anterior. A non-constrained implant was used. The valgus deformity was corrected intraoperatively and ROM achieved 0–140° of flexion. Discussion It is crucial that attention is given not only to the restoration of proper bony alignment but even more importantly to soft tissue balancing. By using the non-constrained implant, the cost can also be reduced and suitable for developing countries with limited coverage of state insurance. Conclusion Three months after the surgery, the patient achieved stable and painless knee with 10–90° of flexion and complete correction of her valgus deformity.
