title: Arthroscopically insertable force probes in the rotator cuff in vivo.
abstract: In vivo loading data for the rotator cuff would be of value to scientists and clinicians interested in the shoulder. The Arthroscopically Insertable Force Probe (AIFP; Microstrain, Burlington, VT) offers a potential method for collecting this information. A technique for insertion and retrieval of the AIFP from the subscapularis is described. The method was initially established in a cadaveric model. The AIFP was inserted into the subscapularis tendon in 3 volunteers during diagnostic shoulder arthroscopy. After the motor effects of interscalene block had worn off, dynamic data relating to subscapularis tendon loading was collected. The AIFPs were removed through a port site by traction on a 0 (3.5 metric) nylon suture without complications.
