Summary
Total knee arthroplasty effectively restores motion and function in ankylosed knees. This procedure offers good outcomes without tibial tuberosity osteotomy, provided adequate soft tissue quality is present.
Area of Science:
- Orthopedic Surgery
- Reconstructive Surgery
Background:
- Ankylosed knees present significant challenges for total knee arthroplasty.
- Restoring range of motion and function is crucial for patient quality of life.
Purpose of the Study:
- To evaluate the efficacy of total knee arthroplasty (TKA) in patients with previously ankylosed knees.
- To assess functional outcomes and complications associated with TKA for ankylosed knees.
Main Methods:
- A retrospective review of seven patients (10 knees) undergoing TKA for ankylosed knees between 1995 and 2008.
- Surgical techniques included rectus snip and V-Y quadricepsplasty in select cases.
- Clinical outcomes were assessed using range of motion (ROM), Knee Society (KS) Knee Score, and KS Function Score. Radiographs evaluated implant integrity.
Main Results:
- Significant improvements were observed in ROM (9.5° to 78.5°), KS Knee Score (42.6 to 68.6), and KS Function Score (39 to 66).
- Two cases showed radiolucent lines around the tibial component, and one experienced skin edge necrosis.
- One patient had no improvement in motion.
Conclusions:
- Total knee arthroplasty can achieve favorable motion and function in patients with ankylosed knees.
- The procedure can be performed without tibial tuberosity osteotomy in cases with good soft tissue quality.
- TKA offers a viable solution for improving quality of life in this challenging patient group.
