NHS England: Even Longer Delays for Total Joint Replacements! What’s the solution?


A recent statement issued by NHS England’s Simon Stevens has caused concern that some patients awaiting elective knee and hip replacement operations may have to wait longer than is presently recommended to receive treatment. Current constraints on NHS funding and an increase in demand means budgets are having to be redirected to focus on A&E and cancer care.  The NHS has also stipulated that GPs should considerably reduce the number of people being referred to secondary care Consultants. 

Here are links to articles on this issue:

Are there any therapeutic options open to clinicians which may help alleviate the problems that some patients will face as a result of these changes?


It has been recognised for many years that Viscosupplementation can offer a valuable bridge between conservative care and surgery. Clinical studies have consistently shown intra-articular hyaluronic acid (HA) injections to be safe, efficacious and cost-effective (1-3). 

Before the introduction of the single injection HA OSTENIL® PLUS, OSTENIL® injections were usually administered as a course of up to 5 weekly injections. Mathies et al - in a seminal examination of the relationship between Viscosupplementation and the quality of synovial fluid - showed that Viscosupplementation could delay total knee replacements (TKR) by 4.5 to 6 months, and for some patients up to 12 months. His study also demonstrated that “OSTENIL® was safe and significantly improved symptoms in patients with painful advanced knee OA who were awaiting TKR, and that it improved the quality of life of these patients.” (4) In a larger study which examined the potential of HA for delaying knee arthroplasty, Altman demonstrated that “HA injection in patients with knee OA is associated with a dose-dependent increase in time-to-TKR” (7).

Since the introduction of OSTENIL® PLUS, patients have garnered the same symptom-reducing benefits from a single injection, and for the administering clinician - as well as the patient - the process is a lot more convenient. Significant symptomatic reduction and functional improvement was demonstrated in patients suffering moderate knee OA for up to 6 months following a single injection of OSTENIL® PLUS. (5,6). 




So why aren’t more OA patients in the UK being offered the option to help alleviate symptoms and potentially delay their joint replacement?


One of the major obstacles at present is the “Do not recommend intra-articular HA to treat osteoarthritis” in the current NIHCE guidelines on Knee OA. Although it is important to understand that the NIHCE Guidelines (CG177) DO NOT prohibit clinicians from using OSTENIL. In fact, OSTENIL® PLUS DOES meet the QLY cost to benefit criteria quoted by CG177.

Given the current climate in relation to treating degenerative joint change, clinicians and their patients have a limited number of options left open to them: simple analgesics, NSAIDs, and corticosteroid injections, none of which are entirely benign with prolonged use. Physiotherapy alone is not always an option if the joint has degenerated to such an extent that it makes exercise too painful. All this means that the impact on quality of life due to longer waiting times will be felt even more by an ageing and increasingly overweight population.


If you as an injecting physiotherapist/MSk specialist are receiving an increasing number of referrals of patients suffering symptomatic OA from GPs, have you considered Viscosupplementation as an option?


OSTENIL® injections do not require a Consultant to administer. Instead, local MSk triage services can offer a cost effective solution, providing GPs with an alternative patient treatment pathway, helping avoid unnecessary secondary care referrals - and the associated tariff fee - which would more than cover the cost of an OSTENIL® PLUS injection. As a result, not only would the ever growing demand on secondary care be ameliorated, patient waiting times could be reduced, and clinical outcomes improved.

Why consider topical Sodium Hyaluronate (HA) in the treatment of tendinopathy?


Firstly, the difference between HA and other glycosaminoglycans is that it is non-sulfated, forms in the plasma membrane instead of the Golgi apparatus, and can be very large, with its molecular weight often reaching the millions1. HA is considered to be a key molecule in the tissue regeneration process. It has been shown to modulate via specific HA receptors, inflammation, cellular migration, and angiogenesis, which are the main phases of wound healing7.

In relation to tendinopathies, hyaluronic acid modulates a variety of cellular functions: anti-inflammatory activity, enhanced cellular proliferation and collagen deposition. Studies have shown a link between the inhibition of fibroblast proliferation, with a reduction in the formation of adhesions at the tendon healing site; by limiting the proliferation of fibroblasts, HA may reduce the risk of adhesions.2

It has sometimes been assumed, in relation to tendinopathic change, that because there is an excess of GAGs detectable within the local bio-chemical environment, there is an excess of hyaluronan, which is not necessarily the case. For example, the activity of hyaluronidase (enzymes that catalyse the degradation of hyaluronan) has been shown to increase during the healing of equine superficial digital flexor tendon injuries6.

Multiple studies analysing tendon healing have confirmed that HA reduces the formation of scars and granulation tissue, and also prevents adhesions2. Importantly, HA forms part of the extracellular matrix as a major component of ground substance, giving structure for other GAGs and proteoglycans3. In tendon healing, the GAGs provide a temporary structure in the early stages of the wound4. So without the presence of HA, there is evidence to suggest that other GAGs are of limited use. Also, high levels of HA are thought to be instrumental in scar-less healing by facilitating the movement and proliferation of fibroblasts, and by regulating the production and type of collagen5.

HA also plays an important role as a hydrating agent, being able to absorb 3,000 times its own weight in water4. HA appears to inhibit the expression of key intermediaries for the inflammatory signalling pathways (NF-kB), by reducing the expression of pro inflammatory factors, exogenous HA may reduce the fragmentation of endogenous HA and further stimulate synthesis of endogenous HA.7,8.

Tear supplements


Currently, tear supplements are available as solutions, ointments and gels. They can be used as often as necessary to keep the corneal surface and conjunctiva wet. Preferably, the topical application of a well-formulated tear supplement and lubricating agent should provide relief for both aqueous- and mucin-deficient dry eye. Moreover, functions associated with the lipid layer of the precorneal tear film should not be altered by the tear supplement.

There are several objectives that tear supplements aim to fulfil in the treatment of dry eye.

Objectives of tear supplements




Ideally, tear supplements should fulfil the physico-chemical role of a normal tear film. In addition, they should not disturb corneal metabolism nor be toxic to the eye, even with frequent use. It should also have a refractive index similar to that of the cornea to see correctly. This involves consideration of certain characteristics in the formulation if tear supplements are to resemble physiological tears. These include electrolyte concentration, viscosity, mucomimetic properties, pH, osmolarity and the absence of preservatives.

Most Common Cause of Dry Eye: Meibomian Gland​ Dysfunction


Meibomian glands help to form the superficial layer of fat on the tear film. This reduces the evaporation of the tear fluid, improves stability, protects the surface of the eye and is essential for good visual function. Meibomian Gland Dysfunction (MGD) can lead to dry eye due to increased evaporation. MGD is thus responsible for approximately 60 % of all cases of dry eye alone and for a further 20 % of cases associated with a deficiency in the aqueous tear film phase.

Meibomian Gland Dysfunction (MGD) can therefore be considered as the most common cause of dry eye.

Baudouin et al. presented a new pathological diagram of MGD in an attempt to give a clearer picture of the basic mechanisms involved in the development and interaction of dry eye. It should facilitate a more effective treatment of MGD and dry eye in clinical practice 1:

New Guidelines Offer Hope for Older UK Osteoarthritis Sufferers

A report on how people suffering with symptomatic Osteoarthritis (OA) of the knee may still be able to remain active in sport has just been published in the Clinical Journal of Sport Medicine. Clinical Journal of Sport Medicine: January 2016 - Volume 26 - Issue 1 - p 1–11 doi: 10.1097/JSM.0000000000000274
The authors – who are all members of The American Medical Society for Sport Medicine (AMSSM), an organisation which represents over 2100 nonsurgical sports medicine physicians - carried out a detailed meta-analysis (a process where the results of many different studies are pooled and then subjected to sensitive statistical testing) of all relevant clinical investigations relating to the use of Viscosupplementation published between 1960 and 2014.  Viscosupplementation is an internationally recognised treatment modality for Osteoarthritis of the knee. The process involves injecting Hyaluronic Acid (HA) or Sodium Hyaluronate as it is often referred to, directly into the affected joint. HA is a viscous fluid which closely resembles the natural synovial fluid found in all healthy articular joints...
