title: Fluoroscopically assisted stress radiography for varus-valgus stability assessment in flexion after total knee arthroplasty.
abstract: A radiographic technique to quantify varus and valgus joint laxity in flexion after total knee arthroplasty (TKA) was evaluated by means of inter-rater assessment in 12 patients. The test was shown to have good reliability. The simple method helps to detect instability in knee flexion that might be overlooked in a conventional clinical examination.
