Tendinopathy TOP TEN By Jill Cook PhD
Tendon pain and dysfunction are the presenting clinical features of tendinopathy. Research has investigated many treatment options, but consistent, positive, clinical outcomes remain elusive. We know that treatment should be active (eg, exercise-based), and that a consistent and ongoing investment in rehabilitation is required. It is important to maximise this investment by understanding (and conveying to patients) treatments that do not help. The following 10 points high- light treatment approaches to avoid as they do not improve lower limb tendinopathy.
1. Don’t rest completely.
Rest decreases the load tolerance of tendon, and complete rest decreases tendon stiffness within 2 weeks.1 It also decreases strength and power in the muscle attached to the tendon and the function of the kinetic chain,2 and likely changes the motor cortex, leaving the person less able to tolerate load at multiple levels. Treatment should initially reduce painful, high tendon load (point 2) and intro- duce beneficial loads (eg, isometrics3). Once pain is low and stable (consistent on a loading test each day), load can be increased slowly to improve the capacity of the tendon.4
2. Don’t prescribe incorrect exercise.
Understanding load is essential for correct exercise prescription. High tendon load occurs when it is used like a spring, such as in jumping, changing direction and sprinting.5 Tendon springs must be loaded quickly to be effective, so slow exercises even with weights are not high tendon load and can be used early in rehabilitation. However, exercising at a longer muscle tendon length can compress the tendon at its insertion.6 This adds substantial load and should be avoided, even slowly, early in rehabilitation.
3. Don’t rely on passive treatments.
Passive treatments are not helpful in the long term as they promote the patient as a passive recipient of care and do not increase the load tolerance of tendon.Treatments like electrotherapy and ice temporarily ameliorate pain only for it to return when the tendon is loaded.7
4. Avoid injection therapies.
Injections of substances into a tendon have been shown to be no more effective than placebo in good clinical trials.8 Clinicians who support injection therapies incorrectly suggest they will return a pathological tendon to normal. There is little need to intervene in the pathology as
there is evidence that the tendonadapts to the pathology and has plenty of tendon tissue capable of tolerating high load.9 Injections may change pain in the short term as they may affect the nerves, but should only be considered if the tendon has not responded to a good exercise-based programme.
5. Don’t ignore tendon pain. Pain usually increases 24 hours afterexcess tendon load. An increase in pain of 2 or more (out of 10) on a daily loading test should initiate a reduction in the aspects of training that are overloading the tendon (point 2). The overload is likely to be due to excessive spring-like movements such as jumping, running and changing direction.
6. Don’t stretch the tendon.
Aside from the load on a tendon in sport, there are compressive loads on the bone-tendon junction when it is at its longest length. Stretching only serves to add compressive loads that are detrimental to the tendon.10
7. Don’t use friction massage.
A painful tendon is overloaded and irritated (reactive tendon pathology). Massaging or frictioning the tendon can increase pain and will not help pathology.7 An effect on local nerves may reduce pain in the short term only for it to return with high tendon loads.
8. Don’t use tendon images for diagnosis, prognosis or as an outcome measure.
Abnormal tendon images (ultrasound and MRI) in isolation do not support a diagnosis of tendon pain as asymptom- atic pathology is prevalent. There are also no aspects of imaging, such as vascu- larity and ‘tears’, that allow a clinician to determine outcome.11 Pathology on imaging is usually very stable and does not change with treatment and reductionin pain, so images are not a good outcome measure.12
9. Don’t be worried about rupture.
Pain is protective as it causes unloading of a tendon. In fact most people who rupture a tendon have never had pain and do not present clinically, despite the tendon having substantial pathology.13
10. Don’t rush rehabilitation.
Tendon needs time to build its strength and capacity. So does the muscle, the kinetic chain and the brain. Although this can be a substantial time (3 months or more), the long-term outcomes are good if the correct rehabilitation is completed.14
The above 10 treatment approaches take valuable resources and focus away from the best treatment for tendon pain—exer- cise-based rehabilitation. A progressive programme that starts with a muscle strength programme and then progresses through to more spring-like exercises and including endurance aspects will load the tendon correctly and give the best long- term results.
At first it was just a niggle in your knee when you climbed stairs or were squatting. Then the pain and stiffness became more than a niggle and you began to feel it when walking, sitting and resting.
You may be hearing popping or cracking sounds in your knee, and notice that your knee “gives out” every now and again.
The knee is an amazing but complicated joint and knee pain is one of the most common reasons that people visit a physiotherapist.
Pain behind the kneecap is commonly called runner’s knee because it is often seen in athletes and people with an active lifestyle, although it can also be seen in everyone from the young adolescents during growth spurts to elderly people.
The medical term is patellofemoral pain syndrome. It is pain behind the kneecap where your patella (kneecap) slides along the groove in your femur (thighbone) beneath.
Pain and stiffness occurs when the kneecap does not slide smoothly and misaligns causing it to rub against your femur. Repeated mis-tracking causes pain, stiffness, and ultimately can cause damage to your kneecap joint surface.
Knee pain is most commonly noticed during activities that involve knee bending, jarring or weight bearing.
People most at risk are those whose sport or activity includes running, jumping or the need to land in a squatting position. Sports most commonly associated with knee pain include running, netball, volleyball, basketball, tennis, skiing and cycling. Many tradies such as tilers and carpet layers also have problems.
Causes of Runner’s Knee
Overuse – increased activity or increased duration and intensity of the activity
Changes in footwear or playing surfaces
Tight outer thigh muscles and weaker inner thigh muscles causing the kneecap to be pulled to one side
A twisting injury
Flat feet and lack of arch support
Weak hip control muscles
First aid for Runner’s Knee
Generally, knee pain is gradual onset, which means it gradually increases in severity over time.
As with most injuries, the best initial first aid is rest, ice packs (15 minutes at a time every 2-3 hours), and taking anti-inflammatory painkillers such as ibuprofen.
You do not need a referral from a doctor to see a physiotherapist. If the pain is moderate, then you can seek treatment with your Physiotherapist immediately.
Physiotherapy is a proven treatment for runner’s knee. Your physiotherapist may initially tape or strap your kneecap to help pull it back into alignment and reduce pain.
Massage and joint mobilisation techniques are also commonly used to reduce swelling and restore movement.
You will be prescribed exercises to stretch and strengthen muscles that may be contributing to the problem. These exercises will change as you heal and will gradually increase in intensity to match your recovery.
If you wish to continue exercising to maintain your fitness during your treatment, then explore swimming, deep-water running and low-impact gym equipment such as elliptical trainers.
Depending on your knee pain cause, you may also be advised to explore arch supports, orthotics or different footwear. You may also require postural or technique correction in your chosen sport to stop problems from recurring, as well as a strength and conditioning plan to get you back to full competitive fitness.
In our experience, over 90% of runner’s knee physiotherapy clients will be pain free within six weeks of starting treatment. However, for severely damaged joints or arthritic joints, surgery may be required.
Things to Remember
Runner’s knee or patellofemoral pain syndrome is a common cause of knee pain.
It is a gradual onset injury and is most commonly noticed during activities that involve knee bending, jarring or weight bearing.
Physiotherapy is a proven method to speed healing, and prevent recurrence of knee pain.
Future management may also involve assessment of your gait and posture during exercise, and prescription of arch support or custom made orthotics.
A New England Journal of Medicine (NEJM) study showing that physical therapy is just as effective as surgery in patients with meniscal tears and arthritis of the knee should encourage many health care providers to reconsider their practices in the management of this common injury, according to the American Physical Therapy Association (APTA).
The study, published March 19, showed no significant differences in functional improvement after 6 months between patients who underwent surgery with postoperative physical therapy and those who received standardized physical therapy alone.
“This study demonstrates what physical therapists have long known,” explained APTA President Paul A. Rockar Jr, PT, DPT, MS. “Surgery may not always be the best first course of action. A physical therapist, in many cases, can help patients avoid the often unnecessary risks and expenses of surgery. This study should help change practice in the management of symptomatic meniscal tears in patients with knee osteoarthritis.”
According to lead physical therapist for the trial and American Physical Therapy Association (APTA) member Clare Safran-Norton, PT, PhD, OCS, “our findings suggest that a course of physical therapy in this patient population may be a good first choice since there were no group differences at 6 months and 12 months in this trial. These findings should help surgeons, physicians, physical therapists, and patients in decision-making regarding their treatment options.”
Researchers at 7 major universities and orthopedic surgery centers around the country studied 351 patients aged 45 years or older who had a meniscal tear and mild-to-moderate osteoarthritis of the knee. Patients were randomly assigned to groups who received either surgery and postoperative physical therapy or standardized physical therapy. Within 6-12 months, patients who had physical therapy alone showed similar improvement in functional status and pain as those who had undergone arthroscopic partial meniscectomy surgery.
Patients who were given standardized physical therapy — individualized treatment and a progressive home exercise program — had the option of “crossing over” to surgery if substantial improvements were not achieved. Thirty percent of patients crossed over to surgery during the first 6 months. At 12 months these patients reported similar outcomes as those who initially had surgery. Seventy percent of patients remained with standardized physical therapy.
According to an accompanying editorial in NEJM,”millions of people are being exposed to potential risks associated with a treatment [surgery] that may or may not offer specific benefit, and the costs are substantial.” Physical therapist and APTA member Mary Ann Wilmarth, PT, DPT, MS, OCS, MTC, Cert MDT, chief of physical therapy at Harvard University, said, “Physical therapists are experts in improving mobility and restoring motion. The individualized treatment approach is very important in the early phases of rehabilitation in order to achieve desired functional outcomes and avoid setbacks or complications.”

If you want to steer clear of lower back pain, remember this: Arch is good, flat is bad.
Back pain is anything but rare; only headaches and colds are more common. According to the National Institute of Neurological Diseases and Stroke, Americans spend more than $50 billion each year on lower back pain, which is the No. 1 cause of job-related disability in the country and one of the leading contributors to missed time from work.
There’s acute lower back pain, sometimes intense but generally short-lived discomfort resulting from injury to the lower back incurred during sustained physical activity (playing sports, doing yard work) or by a sudden jolt (being in a vehicle collision). But it’s chronic lower back pain, the kind that lasts for more than three months, that is more debilitating and more difficult to treat.
Much of that chronic pain is caused by damage to the discs — the spongy, multi-function structures that lie between the spine’s vertebrae — in the lower part of the back right above the pelvis known as the lumbar region. And much of that damage is caused by poor body mechanics — the way people stand, walk, lift, carry, reach, bend, sit and sleep — in which the back is too often flat, not arched.
“The key to avoiding lower back pain is keeping pressure off your lower lumbar discs,” said Tadhg O’Gara, M.D., an orthopaedic surgeon at Wake Forest Baptist Medical Center in Winston-Salem, N.C. “That means keeping an arch to your lower back.”
The intervertebral discs, essentially the spine’s shock absorbers, are under constant pressure, especially in the lower back, which supports the weight of the upper body. The five vertebrae in the lumbar region are naturally arched toward the front of the body, so bending forward compresses the front of these disks, which over time can force them out of position to press on one or more of the nerves emanating from the spinal cord. This condition — known as a bulging, herniated or ruptured disc — can cause pain in the lower back and elsewhere, especially the buttocks, thighs and even below the knee (sciatica). And that pain can be severe.
“People who haven’t had lower back pain don’t re alize how painful it is,” O’Gara said. “And many health care providers don’t realize how painful it is.”
So how is chronic lower back pain treated?
“The first thing to figure out is what exactly is causing the pain, because that determines what approach to take with treatment,” said Kristopher Karvelas, M.D., assistant professor of physical medicine and rehabilitation at Wake Forest Baptist. “That’s not always easy. Pain is usually related to the discs, but other causes of low back pain have overlapping symptoms and pain patterns.”
Basic diagnostic methods include physical examination, review of the patient’s medical history and patient descriptions of the onset, location, severity and duration of the pain and of any limitations in movement. Imaging techniques such as X-rays, MRI and CT scans also can be employed to pinpoint the source of pain.
Once the reason behind the pain is determined, the most frequently prescribed treatment is physical therapy, not surgery.
“I typically reserve surgery for patients who have a medical need other than pain,” Karvelas said. “There’s a large toolbox that we can go to for patients, and surgery is the last tool.”
Depending on the individual patient’s condition, physical therapy programs usually include exercises designed to strengthen back and abdominal muscles and to promote proper posture and balance. These can include stretching, swimming, walking and even yoga. But education also is a key element.
“Patients need to recognize that posture and activity are crucial in relieving and preventing back pain,” Karvelas said. “They need to learn what exercises to do on their own and how to do them properly to prevent future flare-ups.
“We can help resolve acute back pain episodes, but when we are talking about chronic back pain, the pain may never resolve completely. However, we do use a team approach to treat patients and teach people how to cope with their pain effectively.
