“…Several tools such as radiofrequency energy (RFE) devices have been developed for the thermal modification of soft tissue structures [ 1 ]. RFE devices generate energy resulting in heat, in accordance with Joules Law, on tissue adjacent to the device due to molecular friction caused by the oscillation of intracellular and extracellular ions [ 2 , 3 ]. Since the end of nineteenth century, multiple studies were conducted on the use of RFE for the treatment of medical conditions such as malignant lesions of the skin, cervix, oral cavity and bladder [ 2 ].…”

“…Monopolar RFE devices include one active electrode and one dispersive electrode, which is generally a grounding pad on the patient. In bipolar devices the energy current passes and is concentrated between the electrodes located within the surgical instrument [ 3 ]. The resulting heat at high temperatures (100°C) causes the destruction of collagen molecules, resulting in adjacent tissue ablation.…”

The role of radiofrequency energy (RFE) devices has been minimally studied in hip arthroscopy. The purpose of this study was to determine the role of RFE devices in hip arthroscopy through a systematic review of the literature. We searched the PubMed database using the following Medical Subject Heading terms: hip arthroscopy, hip radiofrequency, thermal capsulorrhaphy, thermal chondroplasty and radiofrequency debridement. Two authors independently reviewed the literature and included articles based on predetermined inclusion criteria. We excluded review, technique and experimental articles. After title and abstract review, we selected 293 articles for full-text review. Ten articles met the inclusion and exclusion criteria. For the included articles, a total of 305 hips underwent arthroscopy with concomitant RFE treatment at a mean age of 25.7 years. Eight articles presented patient-reported outcome (PRO) instruments, one study did not report an outcome instrument but utilized an evaluation of postoperative range of motion (ROM) and 1 year magnetic resonance image (MRI) and computed tomography (CT) imaging. The remaining article measured only the ROM pre- and postoperatively. Only one of the articles reviewed reported complications. Current evidence on the safety and indications for use of RFE devices in hip arthroscopy is insufficient. The literature shows mixed results regarding its use in hip arthroscopy. Although the use of thermal energy is not without risk, if used judiciously and appropriate precautions are taken to avoid damage to adjacent tissues, those devices can be useful for the treatment of certain intra-articular hip pathologies arthroscopically.

“…Procedures including thermal capsulorrhaphy or plication may be performed to address capsular laxity. 52 In a small study (n = 11 hips) of professional athletes who underwent labral resection and capsular thermal modification of the hip, 81% returned to preinjury level of competition with minimal or no pain. 44 Recently, arthroscopic plication of the iliofemoral ligament has been performed on patients demonstrating significant redundancy and capsular laxity.…”

Recent technological improvements have resulted in a greater number of surgical options available for individuals with hip joint pathology. These options are particularly pertinent to the relatively younger and more active population. The diagnosis and treatment of acetabular labral tears have become topics of particular interest. Improvements in diagnostic capability and surgical technology have resulted in an increased number of arthroscopic procedures being performed to address acetabular labral tears and associated pathology. Associated conditions include capsular laxity, femoral-acetabular impingement, and chondral lesions. Arthroscopic techniques include labral tear resection, labral repair, capsular modification, osteoplasty, and microfracture procedures. Postoperative rehabilitation following arthroscopic procedures of the hip joint carries particular concerns regarding range of motion, weight-bearing precautions, and initiation of strength activities. Postoperative rehabilitation protocols that have been typically used for surgeries such as total hip arthroplasty are often not sufficient for the population of patients undergoing arthroscopic procedures of the hip joint. Postoperative rehabilitation should be based upon the principles of tissue healing as well as individual patient characteristics. As arthroscopic procedures to address acetabular labral tears and associated pathology evolve, physical therapists have the opportunity to play a significant role through the development of corresponding rehabilitation protocols.

“…In this procedure, the articular surface is accessed through a small incision and the part of joint cartilage is removed, either mechanically or by using laser light [7]. Although the benefits of introducing flexible instruments for arthroscopy have been reported [8]- [10], rigid arthroscopic instruments are adopted in current clinical practice. Without sufficient degrees-of-freedom (DoFs) of the elongated rigid instrument, dexterous workspace is highly restricted.…”

This paper presents an Implicit Active Constraints control framework for robot-assisted minimally invasive surgery. It extends on current frameworks by prescribing the external constraints implicitly from the operator motion, forgoing the need for pre-operative imaging; the constraints are defined in situ so as to avoid the use of invasive fiducial markers.A hands-on cooperatively-controlled robotic platform, comprising of a surgical instrument and a compliant manipulator, has been designed for an arthroscopic procedure. The surgical platform is capable of constraining the pose of the instrument so as to ensure it passes through the incision point and does not cause trauma to the surrounding tissue.A flexible arthroscopic instrument is designed and its use is investigated to enlarge reachable and dexterous workspace, increasing the accessibility to the target anatomy.The behaviour of the flexible instrument is analysed. A detailed performance analysis is conducted on a group of subjects for validating the control framework, simulating a minimally invasive arthroscopic procedure. Results demonstrate a statistically significant enhancement in the control ergonomics as well as the accuracy and safety of the procedure.
