• A subvastus approach for total knee arthroplasty (TKA) demands lateral release in case everting the patella is difficult. We reported two cases of TKA using a subvastus approach with a small lateral release, which preserved the synovial layer of the capsule and was limited within the length of the patella.<BR>Case 1. A 60-year-old female with osteoarthritis of both knees was referred to our hospital. She was obese and her body mass index (BMI) was 31.8. There was difficulty in everting the patella when a TKA of her right knee was done via a subvastus approach. The small lateral release, which involved only the fibrous layer, was added. Then, the dislocation of the patella became possible.<BR>Case 2. A 73 year-old male with osteoarthritis of his right knee visited our hospital. A lateral plain radiograph showed an infra-patella whose LT/LP ratio was 0.72. The patella was everted in the same manner as in case 1, and TKA was performed. One option for obtaining a good surgical view in TKA involves turning the patellae over. Lateral release makes dislocation of the patellae easier. A subvastus approach offers the advantage of preserving the vastus medialis muscle; however, there are some cases in which there is difficulty in everting the patellae. In such cases, a small lateral release, involing only the fibrous layer, may be beneficial in reducing damage to the circular vascularity of the patella and exposure of the implant under the skin.
