Primary cemented total hip arthroplasty-an Indian experience

Area of Science:

• Orthopedic Surgery
• Biomaterials Science

Background:

• Total hip arthroplasty (THA) is a common procedure for debilitating hip conditions.
• Cemented arthroplasty remains a widely used technique, particularly with established designs like the Charnley prosthesis.

Purpose of the Study:

• To evaluate the long-term outcomes of Charnley cemented primary total hip arthroplasties.
• To assess pain levels, functional status, and complication rates at a minimum 5-year follow-up.

Main Methods:

• A retrospective study of 50 Charnley cemented primary THAs in 47 patients.
• Preoperative and postoperative assessment including Harris hip score and radiographic evaluation.
• Follow-up conducted over a 9-year period with a mean of 7 years.

Main Results:

• Significant improvement in Harris hip score post-surgery.
• 96% of patients were pain-free at follow-up.
• Only 20% required walking support postoperatively, compared to 90% preoperatively.
• Low complication rates: 4% dislocation, 2% deep infection, and 4-6% radiolucent zones. No deep vein thrombosis or heterotopic ossification.

Conclusions:

• Charnley cemented primary total hip arthroplasty demonstrates durable, favorable long-term outcomes.
• The procedure effectively alleviates pain and restores function in patients with severe hip disease.
• Low rates of revision and serious complications support the continued use of this technique.
