Project description:Routine portal placement for the central compartment should be based on minimizing iatrogenic injury and maximizing access. Anchor placement for labral repair/refixation requires a more distal entry position to accomplish sufficient divergence to avoid perforating the articular surface of the acetabulum. If a standard portal for joint access is moved more distal, this can compromise its utility for addressing intra-articular pathology. In addition, it can be difficult to position this portal sufficiently distally to ensure adequate divergence. Moving the anchor away from the rim to avoid perforation, due to suboptimal portal placement, can result in nonanatomic labral repair. Thus a percutaneous anchor delivery system is advantageous in ensuring adequate divergence without compromising routine portal placement for the central compartment.

Project description:The modified mid-anterior portal is a utilitarian hip arthroscopy working portal that permits dual-portal comprehensive surgery for femoroacetabular impingement and related chondrolabral procedures without the need for interportal exchange. Its distal location facilitates labral reparative and reconstructive procedures while minimizing iatrogenic acetabular chondral damage. The relatively lateral location permits instrument navigation not only along the anterosuperior acetabular rim and anterolateral proximal femur typically required for acetabuloplasty and femoroplasty but even to the posterior regions of the hip in cases of global pincer femoroacetabular impingement and posterior extensions of cam morphology and the anteromedial proximal femur while avoiding direct injury to the lateral femoral cutaneous nerve.

Project description:The popularity of hip arthroscopy has increased significantly over the past decade. It is technically demanding and may be associated with complications such as iatrogenic damage to the articular cartilage or acetabular labrum, compression injuries to the structures in the perineum, and distraction injuries to the leg. Some of these complications can be avoided by paying meticulous attention to the technique and reducing the traction/surgical time. We describe a technique by which the risk of injury to the articular cartilage may be minimized by introduction of the surgical instruments under direct vision, rather than under radiologic control. The described technique is likely to reduce the operating time by addressing the peripheral-compartment pathologies first-without traction. Traction is only required for the central-compartment procedures. Exposure to ionizing radiation is also diminished (eliminated with practice) because the portals are established under direct vision of the arthroscopist.

Project description:In knee arthroscopy, a posteromedial portal is used for various indications including arthroscopic posterior cruciate ligament reconstruction, posterior cruciate ligament avulsion fracture fixation, posterior medial meniscal repair, medial ramp lesion repair, and synovectomy. Making the posteromedial portal is challenging for young and even experienced surgeons. Creating the posteromedial portal in knee arthroscopy is challenging and technically demanding for surgeons because of the thick muscular cover, proximity of the neurovascular bundle, tenacious tough capsule, and excessive fat deposition in the posteromedial knee and thigh region. Access for viewing the posteromedial compartment during different procedures is made simple, safe, and replicable with this technique of creating the posteromedial portal. This article describes a simple way to create the posteromedial portal using a radiofrequency device by a modified outside-in surgical technique.

Project description:Over the past 2 decades, hip arthroscopy has developed as a surgical technique, with more orthopaedic surgeons attempting to become proficient in performing this surgical procedure as indications and surgical skills evolve. The hip joint presents unique arthroscopic challenges because of its anatomic location, and it can be challenging to safely and confidently establish portal sites. Ultrasound-guided hip arthroscopy portal placement is not yet common practice for orthopaedic surgeons. The potential advantages of ultrasound-guided hip arthroscopy portal placement are the lack of radiation exposure to the patient and operating room personnel, direct visualization of the hip joint and surrounding soft-tissue structures, and lack of bulky fluoroscopic equipment in the operative field. We describe a detailed technique incorporating video examples using ultrasound guidance to establish appropriate portal sites for hip arthroscopy with the aim to improve safety and overall operator competence.

Project description:A technique of single portal knee arthroscopy was reported in 2013. Using a parallel working cannula assembled to the arthroscope cannula, the instruments are passed into the joint in line with the arthroscope. The original technique video in Arthroscopy Techniques shows the use of a 25 mm tube assembly with a parallel portal through which biters and proximally bent cutter instruments are used to perform procedures in the knee. This 2015 technical update shows the current preferred and most versatile method of single portal knee arthroscopy using a parallel locking and rotating hub for passage of biters and double-bend cutters. The video shows adequate completion of a partial meniscectomy using only 1 portal.

Project description:Iatrogenic injury is a known complication of initial portal placement during hip arthroscopy. The rate of labral puncture or damage to the articular surfaces with arthroscopic instruments is variable and may be associated with operator inexperience or complex anatomy. In addition, the amount of traction applied to achieve joint distraction may unnecessarily place patients at risk of neurapraxia. The purpose of this article is to describe the "femoral head drop" technique as a method to increase safe access to the central compartment and minimize the amount of traction needed to do so, especially in patients with challenging bony anatomy. This technique uses the application of intra-articular saline solution to cause inferior migration of the femoral head. Intra-articular fluid distension, or the femoral head drop technique, is simple, safe, and reproducible, making it appropriate for hip arthroscopists at any level of experience.

Project description:Hip arthroscopy has been increasing tremendously in the past decade and is a very common surgical procedure to repair femoroacetabular impingement. To access the hip joint, distraction is mandatory to treat intra-articular disorders such as labral tears, cartilage loose bodies, and ligamentum teres tears and to evaluate the condition of the femoral head and acetabular cartilage. To distract the hip, counterdistraction is needed, and this is achieved with placement of a bulky and cushioned perineal post. Most of the described techniques in hip arthroscopy use a perineal post, whereas others use beanbags to place the patient's body on the surgical table. Still others do not use a post at all but rather use gravity and a Trendelenburg position to achieve distraction. Our technique does not use a perineal post but instead uses heavy-duty tape over the patient's upper body, which is placed on a normal operating room table to distract the hip while entering the central compartment.

Project description:Hip arthroscopy has recently become a common procedure to treat central and peripheral hip pathology. Capsulotomies are necessary in these procedures, and negotiating adequate visualization, as well as capsular preservation, is a challenge. We describe a capsular suspension technique that allows for adequate visualization of the central and peripheral compartments while facilitating preservation of the native hip capsule. This technique eliminates the need for additional personnel for retraction, potentially decreases iatrogenic hip injury, eliminates the need for excessive capsular debridement, and allows for capsular closure under minimal tension.

Project description:A new technique of single-portal arthroscopy using new instrumentation for arthroscopic knee surgery is reported. The procedure is intended for "targeted" surgery to address limited pathology. The arthroscope, cutters, and biters are all introduced into the joint through 1 portal. The technique is generally applicable to knee arthroscopy for isolated conditions and potentially useful in treating other joints. A 2.9-mm-diameter, light-sensitive, high-definition, 20-cm-long arthroscope is inserted through a 4.6-mm cannula. This arthroscope-cannula combination yields fluid flow mechanics similar to a standard 4-mm arthroscope in a 5.8-mm cannula. A Parallel Portal Cannula (PPC) (Stryker Endoscopy) is applied to the arthroscope cannula, producing a "double-barrel" system for entry into the joint. The PPC allows for sliding and rotational freedom along the axis of the arthroscope cannula but also locks in place once a desired position is achieved. PPC devices are available in zero-length, short (25-mm), and long (55-mm) sizes. Cutters that are bent in the mid shaft are available in 3.5- and 4-mm diameters. The instrumentation system allows both viewing with the arthroscope and passage of working cutters and biters through a single 9- to 10-mm portal. Potential advantages of single-portal arthroscopy include decreased patient morbidity and recovery time while still allowing for adequate treatment of limited knee pathology.
