Complex Total Knee Arthroplasty for Posttraumatic Osteoarthritis: Assessment, Approach, and Outcomes

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering
• Sports Medicine

Background:

• Posttraumatic knee osteoarthritis (OA) affects nearly one-third of patients after intra-articular fracture or ligamentous knee injury.
• Complex total knee arthroplasty (TKA) is often the best treatment option for these patients.
• These cases present unique surgical challenges, including prior incisions, implant issues, deformities, bone defects, and stability concerns.

Purpose of the Study:

• To review the challenges and contemporary outcomes of complex total knee arthroplasty in posttraumatic knee osteoarthritis patients.
• To summarize effective surgical approaches for these complicated cases.

Main Methods:

• Literature review focusing on complex total knee arthroplasty for posttraumatic knee osteoarthritis.
• Analysis of surgical planning and execution considerations.
• Evaluation of contemporary outcomes, including complications and revision rates.

Main Results:

• Complex TKA can lead to significant improvements in pain and function for posttraumatic OA patients.
• However, these procedures are associated with higher complication rates and increased revision risk compared to standard TKA.
• Patient-reported outcomes may be inferior despite functional gains.

Conclusions:

• Effective management of posttraumatic knee osteoarthritis with complex TKA requires careful consideration of specific surgical challenges.
• While offering functional benefits, surgeons must weigh the increased risks and potential for inferior outcomes.
• Further research and technological advancements are needed to optimize outcomes in this patient population.
