Objective
To compare collared vs. collarless femoral stems used in total hip replacement (THR) and assess their performance in terms of early implant movement, patient satisfaction, pain, and complication rates.
Key Findings
- Collared stems showed slightly less early implant movement (subsidence).
- There were no significant differences in pain, satisfaction, or complications between collared and collarless stems.
- Both stem designs provided good long-term improvements after surgery.
Conclusion
While collared stems may offer minor benefits in early stability, both types of stems are effective for hip replacement. The choice between them can depend on the surgeon's preference and the patient's specific anatomy.
What Does This Mean For Patients
If you're considering a hip replacement, both collared and collarless stems are effective. The choice of stem type will likely depend on your surgeon’s recommendation and your hip anatomy, with both options leading to good outcomes.
