Carpal tunnel release using the KnifeLight technique: An alternative to endoscopic approach?

Abstract

Introduction and importance

Carpal tunnel syndrome (CTS) is caused by compression of the median nerve, leading to both sensory and motor dysfunction in the hand. Traditional open carpal tunnel release (CTR) is a proven treatment but often results in longer recovery times, visible scarring, and postoperative issues like pillar pain. Endoscopic techniques, while reducing recovery time and limiting incision size, present risks such as incomplete ligament release and possible nerve injury. This underscores the need for a surgical approach that combines the advantages of both methods while minimizing their downsides.

Surgical technique and Case presentation

This article introduces a minimally invasive surgical technique for CTR using the KnifeLight instrument. The procedure involves a small incision and integrates a light source for improved visualization. This setup enables precise division of the transverse carpal ligament, reducing the risk of damage to surrounding structures. Each step of the procedure is detailed, highlighting its advantages over both traditional open and endoscopic CTR.

Clinical discussion

The KnifeLight technique enables more controlled and accurate ligament release, resulting in reduced scarring and quicker recovery. Initial data indicate that patients experience less postoperative discomfort and shorter rehabilitation compared to traditional CTR. This method's precision also reduces the risk of complications, such as nerve damage or incomplete ligament release. The KnifeLight procedure represents a promising middle ground between open and endoscopic CTR. It combines the visual clarity and precision of open surgery with the benefits of a smaller incision and quicker recovery typical of endoscopic methods. The built-in light source enhances visualization, ensuring both patient safety and effective ligament release. However, further comparative studies are needed to fully assess its long-term outcomes and potential complications.

Conclusion

The KnifeLight technique for carpal tunnel release offers a strong alternative to both open and endoscopic CTR methods. It minimizes scarring, shortens recovery time, and improves overall patient outcomes, making it a potential future standard for treating CTS. Further research and broader clinical adoption are necessary to confirm its long-term efficacy and safety.
