Primary total hip reconstruction with a titanium fiber-coated prosthesis inserted without cement

Area of Science:

• Orthopedic Surgery
• Biomaterials Engineering
• Medical Device Technology

Background:

• Total hip arthroplasty (THA) is a common procedure for hip joint disease.
• Cementless fixation aims to promote bone ingrowth for long-term implant stability.
• The Harris-Galante prosthesis utilizes a porous titanium-fiber coating to facilitate osseointegration.

Purpose of the Study:

• To assess the intermediate-term clinical and radiographic outcomes of cementless total hip arthroplasty.
• To evaluate the performance and survivorship of the Harris-Galante porous titanium-fiber-coated femoral prosthesis.
• To identify potential complications associated with this uncemented implant system.

Main Methods:

• Prospective study of 121 total hip arthroplasties in 110 patients.
• Implantation of the Harris-Galante porous titanium-fiber-coated prosthesis without cement.
• Follow-up included clinical assessment (Harris hip score) and radiographic evaluation.
• Survivorship analysis was performed at a minimum of five years.

Main Results:

• Average Harris hip score improved significantly from 55 preoperatively to 93 postoperatively.
• A 97% five-year survival rate was observed for the cementless Harris-Galante femoral stem.
• Complications included one acetabular component revision for dislocation and four femoral implant revisions due to instability.
• Cortical bone erosion around the distal femoral stem occurred in 8% of patients with stable implants.

Conclusions:

• The cementless Harris-Galante femoral stem demonstrates favorable intermediate-term survivorship in total hip arthroplasty.
• Significant functional improvement was achieved in patients undergoing this procedure.
• While generally successful, potential complications such as instability and cortical erosion warrant continued monitoring.
