Summary
This study evaluated Sheehan total knee arthroplasty in 405 knees over 2-11 years. Results show complications mainly from the patella and femorotibial joint, supporting long-stem implants.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
- The Sheehan prosthesis is a specific TKA design.
- Long-term outcomes and complication profiles of TKA designs are crucial for clinical decision-making.
Purpose of the Study:
- To assess the clinical outcomes of Sheehan total knee arthroplasty.
- To document complications associated with this specific TKA design.
- To evaluate factors influencing the success of Sheehan TKA and assess the utility of long-stem components.
Main Methods:
- A retrospective review of 405 Sheehan total knee arthroplasty procedures performed at two centers.
- Clinical results were assessed, and complications were systematically documented.
- Follow-up duration ranged from two to eleven years.
Main Results:
- The primary complications observed were related to the patella and the femorotibial articulation.
- A low rate of implant loosening was noted.
- Satisfactory alignment was achieved in the majority of cases.
Conclusions:
- The Sheehan total knee arthroplasty demonstrates a low rate of loosening and achieves satisfactory alignment.
- Complications are primarily localized to the patella and femorotibial joint.
- The findings support the use of a long-stem design for Sheehan total knee arthroplasty.
