As a minimally invasive technique, needle-knife therapy has demonstrated remarkable efficacy in the treatment of stenosing flexor tenosynovitis. The accuracy of selection points directly influences the success rate of needle-knife therapy, with palpation serving as a traditional and crucial method for determining treatment points. Hard nodules and tender points, as the primary bases for point selection, assist physicians in identifying the pathological area. With the advancement of medical technology, modern imaging techniques such as ultrasound guidance have been introduced into needle-knife therapy, enhancing the accuracy of point selection and the safety of treatment. This review explores improved approaches to point selection in needle-knife therapy, emphasizing the integration of modern imaging techniques and anatomical basic research to achieve more precise lesion localization. Meanwhile, it proposes identifying areas devoid of nerves and blood vessels during point selection to adhere to the principle of minimal injury and reduce the impact on surrounding normal tissues. By adopting this method, more personalized and precise treatment plans can be provided to patients, thereby improving treatment outcomes and reducing postoperative complications.
