What is Sports Medicine？
Where there is life, there is movement. In recent years, with the general improvement of people’s living standards, the national fitness movement has become a new fashion, widely carried out all over the country, but there will be exercise, there will be strain, strain will produce disease, so sports injury diseases are frequent, in this context, the field of sports medicine has been widely concerned by the society.
Sports medicine originated in orthopedics, but it is different from traditional general trauma orthopedics. Sports medicine often focuses on the study of soft tissue injuries such as cartilage, ligament and tendon, and pays more attention to sports-related injuries. It is different from orthopedics in terms of incidence, diagnosis and treatment principles, prognosis, etc. In order to better deal with sports injuries, sports medicine is separated from orthopedics.
Sports medicine clinical treatment range
Clinical sports medicine covers the treatment and rehabilitation of shoulder, hip, knee and small joint diseases. Acute injuries such as fractures, sprains, strains, dislocations, and chronic strains including tendinitis, degenerative diseases, and overtraining syndrome also fall under the umbrella of sports medicine. In general, as long as it is sports-related injuries, basically included
Sports medicine arthroscopic surgery system
Sports medicine equipment mainly includes arthroscopic surgery system and arthroscopic surgery consumables. During clinical operations, doctors can observe the joint cavity and specific tissue space through small surgical incisions and soft tissue channels with the help of arthroscopes, so as to observe and analyze the lesion structure, which has a good therapeutic and diagnostic effect on diseases such as cartilage injury, articular surface fracture, intra-articular ligament and tendon injury. At the same time, arthroscopic surgery is widely used in medical diagnosis and treatment because of its characteristics of less trauma and quick recovery.
At present, the main materials for sports medicine products include medical titanium, inorganic non-metallic materials (hydroxyapatite, etc.), polymer materials (polyether ether ketone, ultra-high molecular weight polyethylene – suture) and absorbable materials such as polylactic acid. From the perspective of material replacement, the field of sports medicine has experienced the change of titanium alloy → absorbable material → polyether ether ketone (PEEK) composite material.
Polyether ether ketone (PEEK) has been widely used in sports medicine, such as: anchor with wire, interface screw, meniscus repair system and so on.
Knee joint (ligament area)–Interface screw：Interfacial screws are commonly used in knee ligament surgery. They are mainly used as extrusion nails near the femoral end. At present, there are mainly metal, PEEK and absorbable materials, of which PEEK has replaced metal to become the mainstream material, absorbable materials due to low mechanical strength, loose, inflammation and other risks, clinical use is relatively less.
Shoulder consumables – Anchor with thread：It is primarily used to treat rotator cuff, ligament tears or other intraarticular injuries. Traditional metal anchors are prone to complications such as loosening, pulling out and cartilage injury, and the appearance of high-strength sutures increases the load at the joint of the threaded anchors, thus increasing the risk of cutting at the joint. PEEK ribbon anchors can avoid these problems. At the same time, compared with absorbable anchors, PEEK has higher strength and X-ray penetration, and post-operative examination does not have to worry about metal artifacts, and its elastic modulus is between cortical bone and cancellar bone, which can reduce stress masking and promote bone healing.
Knee joint (meniscus area)- meniscus Repair System:The purpose of meniscus repair surgery is to preserve the structure of meniscus as much as possible and maintain the protective function of meniscus to the knee joint to the maximum extent. The meniscus repair system is the main consumable for total internal meniscus repair surgery. Each meniscus repair system is equipped with a set of internal plants, including anchors and sutures. From the product material point of view, the current basically to PEEK material.
The development of various minimally invasive repair and reconstruction technologies in sports medicine relies on a large number of high-end and fine surgical instruments and equipment. In the field of implantable medical devices, high-quality upstream raw materials are decisive factors for the safety and effectiveness of implantable products. At present, metal materials have more choices than polymer materials suppliers. Polymer materials, especially the upstream materials with PEEK as the core are expensive, and there are only a handful of suppliers around the world. Guangzhou Juseng Medical Technology Co., Ltd. independently developed and produced medical implantable polyether ether ketone (PEEK) materials with excellent performance and low price, which are suitable for all kinds of sports medical implant devices.
