Evidence for a Hip Aetiology in Patellofemoral Pain

From Prospective Evidence for a Hip Etiology in Patellofemoral Pain. Brian Noehren, Joseph Hamill, Irene Davis: Med Sci Sports Exerc. 2013;45(6):1120-1124. Abstract Purpose: Patellofemoral pain (PFP) is the leading cause of knee pain in runners. Proximal and distal running mechanics have been linked to the development of PFP. However, the lack of prospective studies limits establishing a causal relationship of […]



Tendinopathy is a term used for painful conditions occurring in and around tendons in response to injury and/or overuse and ageing. The natural course of symptoms is variable but most ultimately resolve (even if the tendon appearance on scans does not). Generally the length of symptoms varies according to age and severity.  A recent study suggested the median length of symptoms was 14 months. The incidence of symptoms in sedentary people is highest in middle age though at particular sites (lateral hips and shoulders) the incidence is greater with increasing age.

Ultrasound can confirm or rule out the diagnosis but the presence of tendinopathy on ultrasound does not necessarily indicate whether it is the cause of your symptoms.  The relationship between symptoms and the scan findings is determined by a clinician who combines the clinical history, examination findings, and all test and scan results. The incidence of asymptomatic tendinopathy also increases with age (i.e. many patients have scan findings of tendinopathy but no real symptoms).

A well performed ultrasound or MRI scan will determine whether there are significant tendon tears, inflammation, bursitis, or other nearby soft tissue pathology. It can broadly categorise the type of tendinopathy which usually helps in determining treatment options.


How effective is Ultrasound guided carpal tunnel injection?

The following study was conducted in 2003 by Dr. Iain Duncan.  The information is relevant to Doctors referring patients to me suffering from Carpal tunnel syndrome.  Patients should note that this information is research only and technical in nature. This information should be used in consultation with your treating physician and may only be relevant in certain medical situations.


MSK Ultrasound

Musculoskeletal ultrasound is a subgroup of  diagnostic ultrasound. Iain has been a pioneer in the use of musculoskeletal ultrasound for both diagnosis and guided injection therapy. He has performed over 30,000 therapeutic injections.                   Musculoskeletal ultrasound is best used to assess specific structures that are suspected to be abnormal […]
