Summary
Cementless total hip arthroplasty using the Harris-Galante implant showed a 4.1% revision rate for stem loosening. Clinical outcomes were generally excellent, though some fractures and erosions occurred.
Area of Science:
- Orthopedic Surgery
- Biomaterials Science
Background:
- Cementless total hip arthroplasty (THA) is a common procedure for hip joint restoration.
- Assessing long-term outcomes and potential complications of specific THA systems is crucial for patient care.
Purpose of the Study:
- To evaluate the clinical and radiographic outcomes of the cementless Harris-Galante total hip arthroplasty system.
- To identify the incidence of complications such as loosening, revision, fractures, and erosions.
Main Methods:
- A retrospective review of 111 patients (121 hips) who underwent cementless THA with the Harris-Galante implant.
- Clinical assessment using the Harris protocol and radiographic evaluation at an average of 67 months follow-up.
Main Results:
- A 4.1% revision rate for stem loosening was observed, with 9.1% showing signs of loosening.
- No acetabular loosening required revision; one socket revision was due to dislocation.
- Intraoperative femur fractures occurred in 7.9% of cases, with 2 leading to stem instability.
- Endosteal cortical erosions were noted in 8.3% of stable stems, potentially due to biological reactions.
Conclusions:
- The Harris-Galante cementless THA demonstrates good clinical results with a low rate of acetabular revision.
- Stem loosening, intraoperative fractures, and endosteal erosions are potential complications requiring further investigation.
