A very common overuse injury causing pain at the tendon below the patella (kneecap). Cyclists often continue with this pain for quite some time until it gradually causes to much pain to push down during the pedal stroke.
What causes Patellar tendinopathy?
Changes in loading (stress), or the tendons ability to deal with this loading causes changes within the structure of the tendon. This may initially cause some inflammation and pain. However it is the changes to the structure of the tendon and its ability to take forces being applied to it that ultimately lead to the drop in performance and pain we see with this condition.
Sudden changes in training volume and intensity are commonly cited as the cause of the problem - e.g taking up riding for the first time or building up for a bigger event.
A new bike, a new position or bike fit,
Increase in cycling on hilly or mountainous terrain.
Pedaling with a very low cadence of high gear (this is known as over-gearing)
A history of pain in the front of your knee is also linked to a greater risk of developing patellar tendinopathy.
Relative quadriceps muscle weakness and also over reliance upon the knee to generate power when cycling
What are the symptoms?
Pain is always very well localised to the tendon and will be tender to the touch. The tendon is located between the lower point of the kneecap and the bony bump at the top/front of your shin bone (tibia).
It is often most tender at the very top, at its attachment to the kneecap.
In very acute cases there may be some slight swelling or thickening to the tendon compared to the other side.
In cycling, riders will complain of pain during the down stroke (power phase) of pedaling. However, it is often worst at the beginning of the ride, before easing off (sometimes completely), and then coming back towards the end of the ride or afterwards.
How can I manage Patellar tendinopathy?
Settle Acute Symptoms
If there is minor swelling and pain when not cycling then it is worthwhile icing the area regularly through the day.
Tips for Icing: 20 mins at a time. Do not place ice directly on skin (use thin towel). Allow at least 1 hour between each application
You can consider the use of ibuprofen to help with both the pain and the possible presence of acute inflammation. **Please consult with your doctor before commencing any course of medication**
Taping the knee may also provide short term pain relief and allow acute symptoms to settle more quickly - it is best to see an experienced physio to help with this but here is a demonstration of the technique. Book a Physiotherapy consultation
If you are unable to perform any cycling without pain then you must take a short period of total rest from the bike until acute symptoms settle.
The ideal setting to re-introduce cycling is either with your bike on a home trainer or on a wattbike (or other gym bike) that you know to be set up correctly for you. This is preferable as it allows you to time a specific session, stop early, use the resistance tolerated rather than what outdoor conditions may dictate.
A tendon’s job is to transfer force from our muscles to our bones and thus generate motion around a joint. As such, it is vital that we maintain and re-build the tendon’s capacity to do so as part of the rehabilitation.
As a general rule, it is acceptable to have some low level discomfort when starting out with strengthening (or loading) exercises but a suggested upper limit for this is 4/10 (in the tendon area) during the exercise. Following that it is expected that the symptoms settle back down completely in 24hrs or the loading is considered beyond the tendon’s current ability to adapt and thus recover.
There are numerous recommendations for how best to start this process and unfortunately there is no single approach that will work equally well for all people. As such it is at this point that it really helps to seek guidance from an a physio who is experienced with both cyclists and tendon rehabilitation.
The most common fitting errors I encounter with clients who present with patellar tendinopathy are:
Saddle height too low
Saddle too far forward
