Total knee arthroplasty using the total condylar III knee prosthesis

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Arthroplasty

Background:

• Total knee arthroplasty (TKA) is a common procedure for knee osteoarthritis.
• The Total Condylar III prosthesis (TCP III) is designed for complex cases requiring intramedullary fixation.
• Evaluating the efficacy of TCP III in both primary and revision TKA is crucial.

Purpose of the Study:

• To clinically and radiographically evaluate the Total Condylar III prosthesis (TCP III) in total knee arthroplasty (TKA).
• To assess the performance of TCP III in both primary and revision TKA procedures.
• To determine the long-term outcomes and implant survivorship of TCP III.

Main Methods:

• A retrospective review of 27 TKAs (24 patients) using TCP III.
• Clinical evaluation using the Hospital for Special Surgery (HSS) knee scale.
• Radiographic evaluation using the Knee Society radiographic method with a mean 4-year follow-up.

Main Results:

• Overall clinical results: 11% excellent, 70% good, 15% fair, 4% poor.
• No significant difference in outcomes between primary and revision TKA.
• Improved pain relief, range of motion, and function post-operatively.
• Radiolucencies observed in 6 tibial and 1 patellar component; no femoral component radiolucencies.
• No correlation between radiographic implant position and clinical outcomes.

Conclusions:

• The TCP III prosthesis is a satisfactory option for TKA in selected knees with significant instability.
• Intramedullary fixation provided by TCP III is suitable for specific patient populations.
• Further long-term studies are warranted to confirm implant survivorship and identify potential complications.
