Encouraging clinical experience has increased the indications for prosthetic knee arthroplasty in haemophiliacs. The medical status, physical disability, age and projected activity levels are the major factors in determining treatment for the patient with unilateral or bilateral haemophilic arthropathy of the knee. In more severely involved knees of patients with haemophilia, flexion contracture is a common deformity. In addition, valgus, external rotation deformity and posterior subluxation of the tibia may exist. The surgeon must have the expertise and experience to correct these deformities sufficiently when performing a total knee arthroplasty. A properly performed soft‐tissue release which achieves balance between the medial and lateral ligamentous structures and posterior capsule can provide stability to the knee with a semiconstrained prosthesis. In cases with severe deformity requiring resection of the posterior cruciate ligament a posterior cruciate substituting prosthesis may be necessary.
