Where is the pain coming from in tendinopathy? It may be biochemical, not only structural, in origin.
No full textOveruse tendinosis, not tendinitis part 2: applying the new approach to patellar tendinopathy.
No full textPatellar tendinopathy causes substantial morbidity in both professional and recreational athletes. The condition is most common in athletes of jumping sports such as basketball and volleyball, but it also occurs in soccer, track, and tennis athletes. The disorder arises most often from collagen breakdown rather than inflammation, a tendinosis rather than a tendinitis. Physicians must address the degenerative pathology underlying patellar tendinopathy because regimens that seek to minimize (nonexistent) inflammation would appear illogical. Suggestions for applying the 'tendinosis paradigm' to patellar tendinopathy management include conservative measures such as load reduction, strengthening exercises, and massage. Surgery should be considered only after a long-term and appropriate conservative regimen has failed

Abstract
This paper discusses the formulation of a quantum mechanical equivalent of the relative time classical theory proposed in Part I. The relativistic wavefunction is derived and a covariant addition theorem is put forward which allows a covariant scattering theory to be established. The free particle eigenfunctions that are given are found not to be plane waves. A covariant partial wave analysis is also given. A means is described of converting wavefunctions that yield probability densities in 4-space to ones that yield the 3-space equivalents. Bound states are considered and covariant analogues of the Coulomb potential, harmonic oscillator potential, inverse cube law of force, square well potential, and two-body fermion interactions are discussed.https://doi.org/10.1071/PH72014
Studies of surgical outcome after patellar tendinopathy: clinical significance of methodological deficiencies and guidelines for future studies. Victorian Institute of Sport Tendon Study Group.
No full textPatellar tendinopathy is often treated surgically after failure of conservative treatment but clinical experience suggests that results are not uniformly excellent. The aim of this review was to (i) identify the different surgical techniques that have been reported and compare their success rates, and (ii) critically assess the methodology of studies that have reported surgical outcomes. Twenty-three papers and two abstracts were included in the review. Surgical procedures were categorized and outcomes summarized. Using ten criteria, an overall methodology score was derived for each paper. Criteria for which scores were generally low (indicating methodological deficiency) concerned the type of study, subject selection process and outcome measures. We found a negative correlation between papers' reported success rates and overall methodology scores (r= -0.57, P<0.01). There was a positive correlation between year of publication and overall methodology score (r=0.68, P<0.001). We conclude that study methodology may influence reported surgical outcome. We suggest practical guidelines for improving study design in this area of clinical research, as improved study design would provide clinicians with a more rigorous evidence-base for treating patients who have recalcitrant patellar tendinopathy

GROWING OLD IN A GLOBAL CITY: THE CHALLENGE OF URBANIZATION FOR ACTIVE AGING IN HONG KONG
No full textThe challenges faced in the design, conduct and analysis of surgical randomised controlled trials
No full textRandomised evaluations of surgical interventions are rare; some interventions have been widely
adopted without rigorous evaluation. Unlike other medical areas, the randomised controlled trial
(RCT) design has not become the default study design for the evaluation of surgical interventions.
Surgical trials are difficult to successfully undertake and pose particular practical and methodological challenges. However, RCTs have played a role in the assessment of surgical innovations and there is scope and need for greater use. This article will consider the design, conduct and analysis of an RCT of a surgical intervention. The issues will be reviewed under three
headings: the timing of the evaluation, defining the research question and trial design issues.
Recommendations on the conduct of future surgical RCTs are made. Collaboration between
research and surgical communities is needed to address the distinct issues raised by the assessmentof surgical interventions and enable the conduct of appropriate and well-designed trials.The Health Services Research Unit is funded by the Scottish Government Health DirectoratesPeer reviewedPublisher PD
