Summary
Custom cementless hip stems improve function and survival in young patients undergoing total hip arthroplasty (THA). This study shows favorable outcomes, including high activity recovery and low complication rates for THA in active individuals.
Area of Science:
- Orthopedic Surgery
- Biomaterials Engineering
Background:
- Total hip arthroplasty (THA) in young, active patients presents unique challenges due to anatomy and activity levels.
- Restoring function and ensuring long-term implant survival are critical in this demographic.
Purpose of the Study:
- To evaluate the efficacy of a three-dimensional custom cementless stem in young patients (<50 years).
- To assess functional restoration, osteolysis, wear, and stem survival rates.
Main Methods:
- Retrospective review of 212 patients (233 hips) younger than 50 years.
- Follow-up duration of 5 to 16 years (mean 10 years).
- Assessment of hip scores (Merle D'Aubigné-Postel, Harris, Hip disability and Osteoarthritis Outcome score) and complications.
Main Results:
- Significant improvement in hip function scores observed.
- No thigh pain reported; 88% achieved full activity recovery and 95% full range of motion.
- 15-year survivorship was 87% (all revisions) and 93% (stem revision only).
- Low rate of femoral osteolysis (5 patients, asymptomatic).
Conclusions:
- Three-dimensional custom cementless stems offer excellent functional restoration and high survivorship in young THA patients.
- These implants demonstrate favorable outcomes compared to standard cementless stems, with a low complication profile.
