Total Knee Arthroplasty on hemophilic arthropathy : About 6 cases

Research Objectives: The objective of our work is to describe the functional results after rehabilitation in hemophiliac patients operated for total knee arthroplasty (TKA).

Design: This is a retrospective descriptive study, carried out over a period of 7 years (2015 to 2022).
with the objectives of recovery of joint mobility, muscle strengthening and walking work.

Setting: the department of physical medicine and rehabilitation at IBN ROCHD University Hospital ; Casablanca ; MOROCCO

Participants: We evaluated a series of 12 TKA placed in seven patients. The mean age of patients was 28.7 years (25-34 ans), five hemophiliacs A and one hemophiliac B.

Interventions: Evaluation consisted of a joint assessment, specifying all complications encountered, before and after rehabilitation which was started immediately postoperatively

Main Outcome Measures: We assessed the satisfaction rate after total knee replacement by the IKS functional score and the quality of life of patients using the SF-36 questionnaire

Results: The increase in joint range was important in all patients with an average of 77.54. We get 94% good and excellent results. The most significant improvement is for pain. Postoperative complications come down to recurrence of subcutaneous hematomas for three patients. According to IKS, pain was rated on average 4.5 preoperatively and 48 postoperatively, the knee score increased to 89.5 postoperatively versus 42.5 preoperatively and the function score increased to 75 postoperatively versus 17.5 preoperatively.
The results of the SF-36 questionnaire show a gain in physical activity after the intervention, which translates into an improvement in quality of life indicators. However, this improvement in functional ability seems to fade over time, which is explained by the involvement of other joints and by intercurrent pathologies.

Conclusions: Total knee arthroplasty has its place in the treatment of chronic arthropathies in hemophilia patients. Our results in this surgery in medium and long-term are good, even excellent, which has improved the quality of life in many hemophilia patients and allowed them to return to work
