Introduction
Kemis® is a minimally invasive, non-endoscopic surgical technique for carpal tunnel release surgery. It combines the safety of open release procedures with the clinical advantages of endoscopic surgery.

Instrument Design
The Kemis® knife features an ergonomic design to minimize the risk of injury to anatomical parts during insertion. The blade is integrated into the knife design to prevent damage to surrounding tissues, ensuring a secure cut of the ligament while preserving the palmar aponeurosis.

Technique Advantages
This technique is simple, reliable, and has a minimal learning curve with reproducible results. It allows immediate visualization of the ligament and distal division of the median nerve, with visual monitoring of anatomical variations. The blade avoids contact with surrounding anatomical parts, reducing the risk of unintentional injury.

Cost-Effectiveness
The Kemis® knife is cost-optimized, single-use, and sterile, eliminating the need for an endoscopy platform or additional equipment. It allows for quick implementation and reduces operating time to 5-10 minutes.

Environmental Impact
The single-use design reduces the need for multiple sterilizations, optimizing the carbon footprint. The lightweight knife (19.5g) also reduces recycling costs.

Postoperative Care
The procedure involves a short 1-2 cm incision, with no damage to the heel of the hand. Recovery time is similar to endoscopic surgery, approximately 21 days.

Surgical Technique
Step 1: Anatomical Landmarks
Incision is made to expose the distal part of the transverse carpal ligament and the thenar eminence. Two lines are drawn to mark the incision location.
Step 2: Exposure of the Transverse Carpal Ligament
The palmar aponeurosis is exposed and incised, and the subfascial adipose tissue is lifted to expose the distal lip of the ligament.
Step 3: Cutting the Transverse Carpal Ligament
The Kemis® knife is placed on the distal lip of the ligament, and regular pressure is applied to cut the ligament.
Step 4: Cautions and Closing
Careful insertion of the knife is required, and the incision is closed with stitches. An adhesive dressing is applied, and finger movement is encouraged.
