Summary
Total knee arthroplasty offers significant pain relief and improved function for hemophilia patients. Careful surgical planning and hematological supervision are crucial for successful outcomes and managing potential complications.
Area of Science:
- Orthopedic Surgery
- Hematology
Background:
- Hemophilia presents unique challenges for surgical interventions, particularly in joint replacement.
- Total knee arthroplasty (TKA) is a complex procedure in patients with bleeding disorders.
Purpose of the Study:
- To evaluate the outcomes of total knee arthroplasty in patients with hemophilia.
- To identify potential complications and technical challenges associated with TKA in this population.
Main Methods:
- Twenty-four TKAs were performed on fourteen patients with hemophilia.
- The Hospital for Special Surgery (HSS) knee-rating system was used for follow-up assessments.
- Patients were followed for two to nine years postoperatively.
Main Results:
- Fifteen knees rated excellent, six good, and one fair using the HSS system.
- Significant improvements in pain, function, and an average 23-degree gain in range of motion were observed.
- Two patients experienced poor outcomes due to late infection; other complications included hematoma, hemolytic anemia, and Factor VIII inhibition.
Conclusions:
- Total knee arthroplasty can be a successful procedure for hemophilic patients, leading to marked functional improvement.
- Strict hematological supervision and preparedness for potential postoperative complications are essential for safe and effective TKA in hemophilia.
