Managing of post-traumatic knee arthritis by total knee arthroplasty: case series of 15 patients and literature review.

Purpose: Post-traumatic arthritis is one of the leading causes of joint disability. This study aims at outlining outcomes of total knee arthroplasty in post-traumatic arthritis and technical difficulty and reviewing literature regarding this issue PATIENTS AND METHODS: We analyzed the outcome of total knee arthroplasty following post-traumatic arthritis in 15 patients with unilateral involvement. Ten had stable arthritic knees treated with posterior stabilized (PS) prosthesis, while five with unstable arthritic knees treated as follows: three with ligamentous instability managed by constrained condylar prosthesis and two with osseous deficiency, metal augmentation used together with stemmed constrained condylar prosthesis (CCK).
