Efficacy of customised foot orthoses in the treatment of achilles tendinopathy : study protocol for a randomised trial

BACKGROUND: Achilles tendinopathy is a common condition that can cause marked pain and disability. Numerous non-surgical treatments have been proposed for the treatment of this condition, but many of these treatments have a poor or non-existent evidence base. The exception to this is eccentric calf muscle exercises, which have become a standard non-surgical intervention for Achilles tendinopathy. Foot orthoses have also been advocated as a treatment for Achilles tendinopathy, but the long-term efficacy of foot orthoses for this condition is unknown. This manuscript describes the design of a randomised trial to evaluate the efficacy of customised foot orthoses to reduce pain and improve function in people with Achilles tendinopathy. METHODS: One hundred and forty community-dwelling men and women aged 18 to 55 years with Achilles tendinopathy (who satisfy inclusion and exclusion criteria) will be recruited. Participants will be randomised, using a computer-generated random number sequence, to either a control group (sham foot orthoses made from compressible ethylene vinyl acetate foam) or an experimental group (customised foot orthoses made from semi-rigid polypropylene). Both groups will be prescribed a calf muscle eccentric exercise program, however, the primary difference between the groups will be that the experimental group receive customised foot orthoses, while the control group receive sham foot orthoses. The participants will be instructed to perform eccentric exercises 2 times per day, 7 days per week, for 12 weeks. The primary outcome measure will be the total score of the Victorian Institute of Sport Assessment - Achilles (VISA-A) questionnaire. The secondary outcome measures will be participant perception of treatment effect, comfort of the foot orthoses, use of co-interventions, frequency and severity of adverse events, level of physical activity and health-related quality of life (assessed using the Short-Form-36 questionnaire - Version two). Data will be collected at baseline, then at 1, 3, 6 and 12 months. Data will be analysed using the intention to treat principle. DISCUSSION: This study is the first randomised trial to evaluate the long-term efficacy of customised foot orthoses for the treatment of Achilles tendinopathy. The study has been pragmatically designed to ensure that the study findings are generalisable to clinical practice.

Eccentric calf muscle training in non-athletic patients with Achilles tendinopathy.

OBJECTIVE: Achilles tendinopathy is prevalent in athletes, but can also affect sedentary patients. We studied the effects of eccentric exercises in sedentary non-athletic patients with Achilles tendinopathy. METHODS: Thirty-four sedentary patients (18 males, average age 44 years, range 23-67; 16 females, average age 51 years, range 20-76; average BMI: 28.6+/-4.7, range 22.1-35.4) with a clinical diagnosis of unilateral tendinopathy of the main body of the Achilles tendon completed the VISA-A questionnaire at first attendance (39+/-S.D. 22.8) and at their subsequent visits. The patients underwent a graded progressive eccentric calf strengthening exercises programme for 12 weeks. RESULTS: Fifteen patients (44%) did not improve with eccentric exercise regimen. Three patients improved after perintendinous injections aprotinin and local anaesthetic. Surgery was performed in seven patients as 6 months of conservative management failed to produce improvements. The overall average VISA-A scores at latest follow up was 50 (S.D. 26.5). CONCLUSIONS: Eccentric exercises, though effective in nearly 60% of our patients, may not benefit sedentary patients to the same extent reported in athletes

Evolving trauma and orthopedics training in the UK.

The ever-growing population of the UK has resulted in increasing demands on its healthcare service. Changes have been introduced in the UK medical training system to avoid loss of training time and make it more focused and productive. Modernizing medical careers (MMC) was introduced in 2005. This promised to reduce the training period for a safe trauma specialist, in trauma and orthopedics, to 10 years. At around the same time, the European Working Time Directive (EWTD) was introduced to reduce the working hours for junior doctors in training, to improve patient safety and also work-life balance of junior doctors. Introduction of the assessment tools from Orthopedic Competency assessment project (OCAP) will help tailor the training according to the needs of the trainee. The aim of this article is to review the changes in the UK orthopedic surgical training over the past two decades

Eccentric calf muscle training in athletic patients with Achilles tendinopathy.

PURPOSE: To evaluate the effects of eccentric strengthening exercises (ESE) in athletic patients with Achilles tendinopathy. METHODS: Forty-five athletic patients (29 men, average age 26 years +/- 12.8, range 18 - 42; 16 women, average age 28 years +/- 13.1, range 20 - 46; average height: 173 +/- 16.8, range 158 - 191; average weight 70.8 kg +/- 15.3, range 51.4 - 100.5) with a clinical diagnosis of unilateral tendinopathy of the main body of the Achilles tendon completed the VISA-A questionnaire at first attendance and at their subsequent visits. The patients underwent a graded progressive eccentric calf strengthening exercises programme for 12 weeks. RESULTS: The mean pre-management VISA-A scores of 36 (SD 23.8; 95% CI: 29 - 46) improved to 52 (SD 27.5; 95% CI: 41.3 - 59.8) at the latest follow up (p = 0.001). Twenty seven of the 45 patients responded to the eccentric exercises. Of the 18 patients who did not improve with eccentric exercises, 5 (mean age: 33 years) improved with two peritendinous aprotinin and local anaesthetic injections. 10 of the 18 patients (9 men, mean age 35 years; 1 woman aged 40 years) who did not improve with eccentric exercises and aprotinin injections proceeded to have surgery. The remaining three patients (3 women, mean age 59.6 years) of the 18 non-responders to eccentric exercises and aprotinin injections declined surgical intervention. CONCLUSIONS: ESE in athletic patients provide comparable clinical outcome compared to our previous results in non-athletic patients. ESE are a viable option for the management of AT in athletes, but, in our hands, only around 60% of our athletic patients benefited from an intensive, heavy load eccentric heel drop exercise regimen alone. If ESE fail to improve the symptoms, aprotinin and local anaesthetic injections should be considered. Surgery is indicated in recalcitrant cases after 3 to 6 months of non operative management

Total hip replacement for acute femoral neck fracture: a survey of National Joint Registries.

Joint registers audit the performance of different types of prosthesis. The data from these registers is invaluable, as the conclusions are evidence based and are not based on the results from a small clinical trial or a case series. The 3rd National Joint Registry Annual Clinical Report (2005) of England and Wales was compared with the latest available online report of other national joint registers, particularly with reference to the usage of total hip replacement performed for fracture of the neck of the femur. In Sweden, total hip replacement is performed for the management of a fracture of the neck of the femur six times more often than in England and Wales, four times more often than in Australia, twice more often than in Canada. Hip fracture registers could provide us with the much needed clinical evidence that could help us solve the last controversy of this unsolved fracture
