Minimally invasive carpal tunnel decompression using the KnifeLight

Area of Science:

• Orthopedic Surgery
• Minimally Invasive Procedures
• Hand Surgery

Background:

• Carpal tunnel syndrome (CTS) is a prevalent condition causing hand pain and dysfunction.
• Conventional open and endoscopic carpal tunnel decompression have limitations.
• Endoscopic surgery requires specialized equipment and training.

Purpose of the Study:

• To evaluate a novel minimally invasive technique for carpal tunnel decompression using the KnifeLight instrument.
• To compare the outcomes of the KnifeLight technique with conventional and endoscopic methods.

Main Methods:

• 44 patients with carpal tunnel syndrome underwent the KnifeLight procedure.
• Preoperative and postoperative assessments included grip strength, pinch strength, and the Michigan Hand Outcomes Questionnaire (MHQ).
• Follow-up evaluations were conducted at 2 weeks, 3 months, and 6 months post-surgery.

Main Results:

• No complications were reported with the KnifeLight approach.
• Patients experienced immediate hand use post-surgery with complete resolution of scar tenderness and incisional pain by 6 months.
• Significant improvements in pain relief, hand function, daily activities, work performance, grip strength, and pinch strength were observed.
• The KnifeLight technique demonstrated the shortest mean operation time and quickest return to work compared to other methods.

Conclusions:

• The KnifeLight facilitates excellent functional outcomes and high patient satisfaction for carpal tunnel decompression.
• This minimally invasive approach is a quick, easy, and effective alternative to conventional and endoscopic surgeries.
