Article Synopsis
- Developed a bone-conserving titanium hip replacement system focusing on osseointegration, designed to leave the femoral canal untouched and properly align with the acetabular cup.
- Conducted a clinical trial with 40 patients comparing the new system to traditional cemented and cementless implants, using various clinical measures over two years.
- Results indicated no significant differences in long-term stability, but better early recovery for patients with the new system, suggesting it may be a viable option for younger, more active individuals.

Article Synopsis
- Developed a new total hip system based on osseointegration, featuring a unique proximal femoral replacement and titanium shell for the acetabulum.
- Conducted a randomized trial with 52 patients comparing the new experimental implant to existing cemented and cementless controls, using clinical measures over three years.
- Results showed no significant differences in hip scores or pain, but some revisions were needed; findings suggest the new implant's potential for osseointegration, though further improvements are necessary before clinical use.
