Mini incision: occasionally desirable, rarely necessary: in the affirmative

Area of Science:

• Orthopedic Surgery
• Arthroplasty Procedures

Background:

• Surgical exposure is critical in total knee arthroplasty (TKA).
• Principles of adequate exposure, including avoiding skin and muscle stretching, are essential for successful TKA.
• Compromising exposure to avoid incisions offers no discernible advantage and can lead to complications.

Purpose of the Study:

• To emphasize the importance of optimal surgical exposure in total knee arthroplasty.
• To highlight the negative consequences of inadequate exposure and skin/muscle stretching.
• To clarify the benefits of proper exposure versus smaller incisions in TKA.

Main Methods:

• Review of fundamental surgical principles applied to knee arthroplasty.
• Discussion of the impact of tissue handling on patient outcomes.
• Analysis of factors contributing to patient recovery, such as pain management and tourniquet use.

Main Results:

• Stretching of skin or muscles during TKA causes damage, pain, and increases infection risk.
• Compromising exposure does not provide benefits and can negatively impact the procedure.
• Improvements in pain management, not smaller incisions, are likely responsible for perceived advantages.

Conclusions:

• Optimal surgical exposure is paramount in total knee arthroplasty.
• Prioritizing adequate visualization and access without tissue stretching is crucial for patient safety and recovery.
• Focus should remain on sound surgical technique for exposure, rather than solely on incision size.
