Brief Summary:

Mini-optics has been used in orthopedics for a short time. The Nanoscope used in this study is marketed by Arthrex. Its main indications concern knee, elbow, wrist, carp and small joints of long fingers for diagnostic and sometimes therapeutic purposes. Some teams use it to replace expensive radiological examinations and/or difficult to access, in consultation, for diagnostic in the knee, but also for therapeutic for partial meniscectomy with several related publications. The investigators recently published a feasibility study of isolated tenotomy of the biceps with this minimally invasive device in consultation (first indexed article describing this technique). This project is part of the broader context of "In Office" surgery, for which there are many applications. Through the miniaturisation of optics and access to "portable" technologies, surgical procedures can now be performed in consultation ("In Office"). For example: release of the carpal tunnel or ulnar canal to the elbow under ultrasound, partial meniscectomy, removal of foreign body from the elbow in consultation. Indeed, in addition to the technical interest of this innovation for a simple and frequent surgical procedure, it should make it possible to transpose anxiety management for the patient, time-consuming and costly for the institution into a heavy technical platform (operating room) towards a simplified, fast and streamlined approach in consultation. In the scientific literature, other equivalent surgical procedures have already been identified and performed in consultation with various tools (carpal tunnel, ulnar nerve in the elbow, meniscectomy in the knee but also in other surgical specialties such as cataract in ophthalmology) with better patient satisfaction, improved patient journey, reduced costs, an increase in the number of patients treated. The investigators wish to demonstrate the non-inferiority of intraarticular tenotomy of the biceps long head performed in consultation with mini-optics and local anaesthesia compared to the operating room in order to modify practices and optimize the management of patients within the institution while improving their satisfaction.
