A technique for difficult arthrodesis of the knee

Area of Science:

• Orthopedic Surgery
• Arthrodesis Techniques

Background:

• Complex knee conditions often require salvage procedures like arthrodesis.
• Previous surgical history and neuropathic involvement present challenges in knee arthrodesis.

Purpose of the Study:

• To evaluate the efficacy of combined Charnley compression and intramedullary nailing for knee arthrodesis.
• To assess outcomes in knees with a history of multiple prior operations.

Main Methods:

• Arthrodesis of twenty knees using Charnley compression and intramedullary nailing.
• Exclusion of patients with prior infection; inclusion of three neuropathic knees.

Main Results:

• Successful bony union achieved in 19 out of 20 knees within an average of six months.
• One case of deep infection resolved after nail removal; no other major complications reported.
• The procedure demonstrated immediate stability and pain relief.

Conclusions:

• The combined Charnley compression and intramedullary nailing technique is a simple and effective method for knee arthrodesis.
• This approach requires limited bone resection and offers significant benefits with minimal morbidity.
• It provides a viable solution for complex knee fusions, including those with neuropathic involvement.
