BACKGROUND: Due to limited regulation of websites, the quality and content of online health-related information has been questioned as prior studies have shown that websites often misrepresent orthopaedic conditions and treatments. Kinesio tape has gained popularity among athletes and the general public despite limited evidence supporting its efficacy. The primary objective of this study was to assess the quality and content of Internet-based information on Kinesio taping. METHODS: An Internet search using the terms "Kinesio tape" and "kinesiology tape" was performed using the Google search engine. Websites returned within the first two pages of results, as well as hyperlinks embedded within these sites, were included in the study. These sites were subsequently classified by type. The quality of the website was determined by the Health On the Net (HON) score, an objective metric based upon recommendations from the United Nations for the ethical representation of health information. A content analysis was performed by noting specific misleading versus balanced features in each website. RESULTS: A total of 31 unique websites were identified. The majority of the websites (71%) were commercial. Out of a total possible 16 points, the mean HON score among the websites was 8.9 points (SD 2.2 points). The number of misleading features was significantly higher than the balanced features (p < 0.001). Fifty-eight percent of sites used anecdotal testimonials to promote the product. Only small percentages of websites discussed complications, alternatives, or provided accurate medical outcomes. Overall, commercial sites had a greater number of misleading features compared to non-commercial sites (p = 0.01). CONCLUSIONS: Websites discussing Kinesio tape are predominantly of poor quality and present misleading, imbalanced information. It is of ever-increasing importance that healthcare providers work to ensure that reliable, balanced, and accurate information be available to Internet users. LEVEL OF EVIDENCE: IV.

CONTEXT: Sidelines coverage presents unique challenges in the evaluation of injured athletes. Health care providers may be confronted with the question of when to obtain radiographs following an injury. Given that most sidelines coverage occurs outside the elite level, radiographs are not readily available at the time of injury, and the decision of when to send a player for radiographs must be made based on physical examination. Clinical tools have been developed to aid in identifying injuries that are likely to result in radiographically important fractures or dislocations. EVIDENCE ACQUISITION: A search for the keywords x-ray and decision rule along with the anatomic locations shoulder, elbow, wrist, knee, and ankle was performed using the PubMed database. No limits were set regarding year of publication. We selected meta-analyses, randomized controlled trials, and survey results. Our selection focused on the largest, most well-studied published reports. We also attempted to include studies that reported the application of the rules to the field of sports medicine. STUDY DESIGN: Retrospective literature review. LEVEL OF EVIDENCE: Level 4. RESULTS: The Ottawa Foot and Ankle Rules have been validated and implemented and are appropriate for use in both pediatric and adult populations. The Ottawa Knee Rules have been widely studied, validated, and accepted for evaluation of knee injuries. There are promising studies of decision rules for clinically important fractures of the wrist, but these studies have not been validated. The elbow has been evaluated with good outcomes via the elbow extension test, which has been validated in both single and multicenter studies. Currently, there are no reliable clinical decision tools for traumatic sports injuries to the shoulder to aid in the decision of when to obtain radiographs. CONCLUSION: Clinical decision tools have been developed to aid in the diagnosis and management of injuries commonly sustained during sporting events. Tools that have been appropriately validated in populations outside the initial study population can assist sports medicine physicians in the decision of when to get radiographs from the sidelines.

Platelet rich plasma (PRP), an autologous sample of blood with a platelet concentration above baseline values, is hypothesized to augment soft tissue healing. Its use in sports medicine has risen dramatically, with common applications including the treatment of refractory tendinopathy and augmenting tendon repair. Many commercial preparation systems are available, but the optimal preparation remains unknown. Increasing numbers of clinical studies evaluating PRP have been reported and have provided both positive and negative evidence for its effectiveness. Well-designed, controlled studies are still lacking, but PRP may have a benefit for patients with tendinopathy that is refractory to other non-surgical treatments. Its use in tendon repair is currently not supported. Randomized, controlled studies with documentation of platelet, white blood cell, and growth factor concentration in the PRP preparation are necessary for future comparative research. Use of PRP should be approached judiciously until further evidence is available.

Platelet-rich plasma is defined as autologous blood with a concentration of platelets above baseline values. Platelet-rich plasma has been used in maxillofacial and plastic surgery since the 1990s; its use in sports medicine is growing given its potential to enhance muscle and tendon healing. In vitro studies suggest that growth factors released by platelets recruit reparative cells and may augment soft-tissue repair. Although minimal clinical evidence is currently available, the use of platelet-rich plasma has increased, given its safety as well as the availability of new devices for outpatient preparation and delivery. Its use in surgery to augment rotator cuff and Achilles tendon repair has also been reported. As the marketing of platelet-rich plasma increases, orthopaedic surgeons must be informed regarding the available preparation devices and their differences. Many controlled clinical trials are under way, but clinical use should be approached cautiously until high-level clinical evidence supporting platelet-rich plasma efficacy is available

Joint and soft tissue injection of the ankle and foot region is a useful diagnostic and therapeutic tool for the family physician. This article reviews the injection procedure for the plantar fascia, ankle joint, tarsal tunnel, interdigital space, and first metatarsophalangeal joint. Indications for plantar fascia injection include degeneration secondary to repetitive use and traumatic injuries that are unresponsive to conservative treatment. Diagnostic aspiration or therapeutic injection of the ankle or first metatarsophalangeal joints can be performed for management of advanced osteoarthritis, rheumatoid arthritis, and other inflammatory arthritides such as gout, or synovitis or an arthrosis such as 'turf toe.' Persistent pain and disability resulting from tarsal tunnel syndrome, an analog of carpal tunnel syndrome of the wrist respond to local injection therapy. A painful interdigital space, such as that occurring in patients with Morton's neuroma, is commonly relieved with corticosteroid injection. The proper technique, choice and quantity of pharmaceuticals, and appropriate follow-up are essential for effective outcomes

Joint injection of the hip and knee regions is a useful diagnostic and therapeutic tool for the family physician. In this article, the injection procedure for the greater trochanteric bursa, the knee joint, the pes anserine bursa, the iliotibial band, and the prepatellar bursa is reviewed. Indications for greater trochanteric bursa injection include acute and chronic inflammation associated with osteoarthritis, rheumatoid arthritis, repetitive use, and other traumatic injuries to the area. For the knee joint, aspiration may be performed to aid in the diagnosis of an unexplained effusion and relieve discomfort caused by an effusion. Injection of the knee can be performed for viscosupplementation or corticosteroid therapy. Indications for corticosteroid injection include advanced osteoarthritis and other inflammatory arthritides, such as gout or calcium pyrophosphate deposition disease. Swelling and tenderness of pes anserine or prepatellar bursae can be relieved with aspiration and corticosteroid injection. Persistent pain and disability from iliotibial band syndrome respond to local injection therapy. The proper technique, choice and quantity of pharmaceuticals, and appropriate follow-up are essential for effective outcomes

The shoulder is the site of multiple injuries and inflammatory conditions that lend themselves to diagnostic and therapeutic injection. Joint injection should be considered after other therapeutic interventions such as nonsteroidal anti-inflammatory drugs, physical therapy, and activity-modification have been tried. Indications for glenohumeral joint injection include osteoarthritis, adhesive capsulitis, and rheumatoid arthritis. For the acromioclavicular joint, injection may be used for diagnosis and treatment of osteoarthritis and distal clavicular osteolysis. Subacromial injections are useful for a range of conditions including adhesive capsulitis, subdeltoid bursitis, impingement syndrome, and rotator cuff tendinosis. Scapulothoracic injections are reserved for inflammation of the involved bursa. Persistent pain related to inflammatory conditions of the long head of the biceps responds well to injection in the region. The proper technique, choice and quantity of pharmaceuticals, and appropriate follow-up are essential for effective outcomes
