Abstract
BACKGROUND:Rotator cuff tendinopathy (RCT) is a significant source of disability and loss of work. Platelet-rich plasma (PRP) has been suggested to be beneficial in the treatment of RCT. PURPOSE:To investigate the effect of PRP injections on pain and shoulder functions in patients with chronic RCT. STUDY DESIGN:Randomized controlled trial; Level of evidence, 1. METHODS:A total of 40 patients, 18 to 70 years of age, with (1) a history of shoulder pain for >3 months during overhead-throwing activities, (2) MRI findings of RCT or partial tendon ruptures, and (3) a minimum 50% reduction in shoulder pain with subacromial injections of an anesthetic were included in this placebo-controlled, double-blind randomized clinical trial. Patients were randomized into a PRP group (n = 20) or placebo group (n = 20). Patients received an ultrasound-guided injection into the subacromial space that contained either 5 mL of PRP prepared from autologous venous blood or 5 mL of saline solution. All patients underwent a 6-week standard exercise program. Outcome measures (Western Ontario Rotator Cuff Index [WORC], Shoulder Pain and Disability Index [SPADI], 100-mm visual analog scale [VAS] of shoulder pain with the Neer test, and shoulder range of motion) were assessed at baseline and at 3, 6, 12, and 24 weeks and 1 year after injection. RESULTS:Comparison of the patients revealed no significant difference between the groups in WORC, SPADI, and

Arthroscopy. 2013 Jul 25;

Authors: Knapik DM, Harris JD, Pangrazzi G, Griesser MJ, Siston RA, Agarwal S, Flanigan DC

Abstract
PURPOSE: To determine whether the basic science evidence supports the use of continuous passive motion (CPM) after articular cartilage injury in the knee.
METHODS: A systematic review was performed identifying and evaluating studies in animal models that focused on the basic science of CPM of the knee. Databases included in this review were PubMed, Biosis Previews, SPORTDiscus, PEDro, and EMBASE. All functional, gross anatomic, histologic, and histochemical outcomes were extracted and analyzed.

Glenohumeral Articular Cartilage Lesions: Prospective Comparison of Non-Contrast Magnetic Resonance Imaging and Findings at Arthroscopy.

Arthroscopy. 2013 Jul 25;

Authors: Spencer BA, Dolinskas CA, Seymour PA, Thomas SJ, Abboud JA

Abstract
PURPOSE: The purpose of this study was to assess the diagnostic sensitivity, specificity, accuracy, negative predictive value (NPV), positive predictive value (PPV), and test-retest reliability of magnetic resonance imaging (MRI) for detecting cartilage abnormalities of the glenohumeral joint in comparison with the gold standard of diagnostic arthroscopy.
METHODS: Forty-four patients with a preoperative non-contrast MRI study of their affected shoulder underwent arthroscopy by one surgeon for rotator cuff tendinopathy from 2009 to 2010. Articular cartilage defects were prospectively recorded and graded according to the International Cartilage Repair Society classification system at the time of arthroscopy. One year after surgery, the preoperative MRI were reviewed by a board-certified radiologist and the treating surgeon for articular cartilage defects of both the humeral head and the glenoid. Sensitivity, specificity, accuracy, and test-retest reliability were calculated.

Imaging at London 2012 summer Olympic Games: analysis of demand and distribution of workload.

Br J Sports Med. 2013 Jul 23;

Authors: Bethapudi S, Budgett R, Engebretsen L, O'Connor P

Abstract
BACKGROUND: Very little data on the provision of imaging services at the summer Olympic Games have been published before. With 7.9 million Euros (£6.6 million, US$11 million) invested into setting up the imaging equipment at the purpose-built polyclinics for London 2012 summer Olympics, an ideal opportunity was presented to study the demand and distribution of workload on imaging services at the games.
SETTING: Imaging services within polyclinics, London 2012 summer Olympic Games.
AIMS: To analyse the demand and distribution of workload on radiology services at the London 2012 summer Olympic Games.
METHODS: Data on radiological investigations performed at London 2012 summer Olympic Games were retrieved from Radiology Information System-picture archiving communication system, ATOS medical encounter database and analysed.
RESULTS: 1711 diagnostic and interventional procedures were performed at the Stratford Polyclinic within the main games village. Of these 48.8% were MRI scans, 20.2% were diagnostic ultrasound examinations, 23.6% were plain radiographs, 2.9% were CT scans and interventional procedures accounted for 4.3%. Nearly 75% of imaging was performed on athletes while less than 5% of the services were utilised by the workforce. Demand on radiology services peaked during week 2 of the games.

Getting Scotland on the move? Reflections on a 5-year review of Scotland's national physical activity strategy.

Br J Sports Med. 2013 Jul 23;

Authors: Halliday E, Mutrie N, Bull F

Abstract
The public health risks of physical inactivity have led many national governments to develop policies that aim to increase population levels of physical activity. There is however, little evidence available about the effectiveness of such strategies and physical activity leaders may also face challenges in securing sufficient levels of political will and lasting investment for physical activity. This article reports on a review of a national physical activity strategy in Scotland after 5 years of implementation and offers lessons that may assist policymakers, practitioners and communities seeking to mobilise political commitment and leadership for physical activity in their own countries.

Consensus criteria for defining 'successful outcome' after ACL injury and reconstruction: a Delaware-Oslo ACL cohort investigation.

Br J Sports Med. 2013 Jul 23;

Authors: Lynch AD, Logerstedt DS, Grindem H, Eitzen I, Hicks GE, Axe MJ, Engebretsen L, Risberg MA, Snyder-Mackler L

Abstract
BACKGROUND: No gold standard exists for identifying successful outcomes 1 and 2 years after operative and non-operative management of anterior cruciate ligament (ACL) injury. This limits the ability of a researcher and clinicians to compare and contrast the results of interventions.
PURPOSE: To establish a consensus based on expert consensus of measures that define successful outcomes 1 and 2 years after ACL injury or reconstruction.
METHODS: Members of international sports medicine associations, including the American Orthopaedic Society for Sports Medicine, the European Society for Sports Traumatology, Surgery, and Knee Arthroscopy and the American Physical Therapy Association, were sent a survey via email. Blinded responses were analysed for trends with frequency counts. A summed importance percentage (SIP) was calculated and 80% SIP operationally indicated consensus.
