Minced Cartilage Implantation for a Cystic Defect on the Femoral Head—Technical Note

ABSTRACT: Chondral injuries of the femoral head and their possible progression to osteoarthritis is well known. Regarding focal lesions in young patients, microfracturing or autologous chondrocyte implantation (ACI) are the most frequent used techniques to address them. Although ACI provides the better tissue quality, it is a two-step procedure and needs a lot of resources. Mincing cartilage is an old technique that has become popular again over the last few years, with good short-term results in threatening cartilage lesion in the knee. It seems intriguing to transfer this technique to the hip because you can harvest good-quality cartilage from the cam lesion, and it is a one-step procedure using autologous thrombin and fibrin. This technical note describes the repair of a parafoveal chondral defect using minced cartilage via surgical dislocation of the hip. Technique Video Video 1 Minced cartilage implantation for a cystic defect on the femoral head. Twenty-seven-year-old patient with a parafoveal chondral lesion, patient history (00:06 min), imaging (00:22), intraoperative findings (00:59), preparing of the cartilage defect (01:10), mincing and harvesting of the cartilage with the GraftNet device (Arthrex, Munich, Germany) (01:30), getting a membrane-like structure of the minced cartilage (01:46), implantation of the minced cartilage into the defect (01:58), sealing of the construct with PRP and autologous thrombin (02:16), and postoperative imaging and care (02:28).

Arthroscopic Minced Cartilage Implantation (MCI): A Technical Note.

Project description:Articular cartilage lesions are identified with increasing frequency. Several cartilage repair techniques are available to treat symptomatic cartilage defects. The ultimate goal of any cartilage repair procedure is the prevention of premature osteoarthritis. Autologous chondrocyte implantation provides the best tissue quality. However, 2 operations and a resource-intense culturing process with high regulatory demands are disadvantages of this cartilage repair procedure. Furthermore, cellular dedifferentiation and senescence display further cell culture-associated drawbacks that hamper the procedure. Minced cartilage implantation is a relatively simple and cost-effective one-step procedure with promising biologic potential and satisfying clinical results. We present an arthroscopic surgical technique where the surgeon can apply autologous chondrocytes in a one-step procedure to treat articular cartilage defects at the knee joint.

Arthroscopic Minced Cartilage Implantation for Chondral Lesions at the Talus: A Technical Note.

Project description:In the past few years, autologous chondrocyte implantation has been shown to be the most suitable cartilage reconstructive technique with the best tissue quality. Although this method is part of the standard surgical repertoire in the knee joint, it has so far not been an established method in the ankle because there are no prospective randomized controlled studies to prove a significant advantage over alternative methods of cartilage repair. The methods most frequently used in this context (e.g., marrow stimulation techniques) can, however, at most generate hyaline-like and thus biomechanically inferior regenerates. Minced cartilage implantation, on the other hand, is a relatively simple and cost-effective 1-step procedure with promising biological potential and-at least in the knee joint-satisfactory clinical results. We present an arthroscopic surgical technique by which the surgeon can apply autologous chondrocytes in a 1-step procedure (AutoCart; Arthrex, Munich, Germany) to treat articular cartilage defects in the ankle joint.

Arthroscopic Reduction and Internal Fixation for Pipkin Type I Femoral Head Fracture: Technical Note.

Project description:Femoral head fractures after posterior dislocation of the hip are uncommon and are conventionally treated by an open method. Hip arthroscopy can be a valuable treatment option for the management of femoral head fractures. Arthroscopy allows for a less invasive option when compared with arthrotomy and can allow faster recovery with minimal soft-tissue injury. We describe the arthroscopic reduction and internal fixation of Pipkin type I femoral head fractures with a detailed stepwise description of the surgical technique, including technical pearls and pitfalls, potential complications, and advantages and disadvantages.

Technical Note for Transfemoral Implantation of Tapered Revision Stems. The Advantage to Stay Short.

Project description:BackgroundThe aim was to test the hypothesis that during transfemoral implantation of a conical revision stem, the fixation of the stem at the distal tip leads to a low rate of periprosthetic fractures.Material and methodsTwo hundred eighty-two stem revisions by a transfemoral approach in cases of Paprosky Type II and IIIA-defects (with a sufficient isthmus) were carried out and analyzed during and radiographically after the surgery for unintentional periprosthetic fractures below the osteotomy.ResultsIn all cases, fixation was always achieved at the tip of the distal component in the isthmus of the femur. No periprosthetic fractures were observed.ConclusionsWhen the isthmus of the femur is intact, a transfemoral implantation of a tapered revision stem at the distal end reduces the risk of periprosthetic fractures by preventing bypassing the isthmus with the stem. Knowing the difference between the nominal diameter and the diameter at the distal start of the conical zone can help to create this fixation technique resulting in short revision stems.

Treatment of glenoid chondral defect using micronized allogeneic cartilage matrix implantation.

Project description:Focal chondral lesions of the glenohumeral joint, though less common than chondral defects in the knee or ankle, can be a significant source of pain in an active population. For patients in whom nonsurgical management fails, promising results have been reported after arthroscopic microfracture surgery to treat such lesions. However, microfracture leads to growth of fibrocartilage tissue and is biomechanically less durable than native hyaline cartilage. Recently, augmentation of the microfractured defect with micronized allogeneic cartilage and platelet-rich plasma has been described to restore hyaline-like cartilage and potentially protect the subchondral bone from postsurgical fracture biology within the base of the defect. We present a simple arthroscopic technique of implanting dehydrated, micronized allogeneic cartilage scaffold to treat an isolated chondral lesion of the glenoid.

Second-Generation Autologous Minced Cartilage Repair Technique.

Project description:Articular cartilage defects at the knee joint are identified and treated with increasing frequency. Autologous chondrocytes may have the strongest potential to generate high-quality repair tissue within the defective region. Autologous chondrocyte implantation is not available in every country. We present a surgical technique where the surgeon can apply autologous chondrocytes in a one-step procedure to treat articular cartilage defects at the knee joint.

Extractable proteoglycan from human femoral-head articular cartilage.

Project description:Proteoglycans were prepared from human femoral-head articular cartilage by using either guanidinium hydrochloride or MgCl2 as extractant, followed by density-gradient centrifugation. The proteoglycan subunit had a particle weight of 2.6 x 10(6), with a radius of gyration, RG, of 68.5 nm in 150 mM-NaCl/20 mM-sodium phosphate buffer, pH 7.0. The proteoglycan aggregate had a particle weight of 3.7 x 10(6) (RG 84 nm) for guanidinium hydrochloride extracts and 8.7 x 10(6) (RG 118 nm) for MgCl2 extracts in the same buffer. The addition of excess of high-molecular-weight hyaluronate did not significantly alter the particle size of the aggregate. The small increase in size probably reflects a rapid equilibrium between hyaluronate and proteoglycan monomers, and is not due to proteolytic cleavage producing non-aggregating units. Experiments that support the rapid-interaction hypothesis include analytical ultracentrifugation and column chromatography. This interaction does not appear to be pressure-sensitive at 20 degrees C, but is sensitive to temperature variation near the physiological range.

Treatment of a patellar chondral defect using juvenile articular cartilage allograft implantation.

Project description:Focal articular cartilage defects of the knee commonly occur. Various arthroscopic and open procedures have been developed to address these lesions when they are symptomatic, all aimed at defect filling. Juvenile cartilage transplantation procedures have recently been described as an option for managing symptomatic cartilage lesions. We present a technique using transfer of juvenile cartilage allograft transplantation into the defect with subsequent second-look arthroscopy and biopsy results after implantation.
