It's funny how this job works: unusually last weekend I had 2 clients in the space of 24 hours both with knee pain caused by inflammation of the patellar tendon.
The 1st client was a 28 year old part-time instructor of a popular hard-core exercise class; the 2nd was a 36 year old who had just started exercising at the gym and was really going for it.

The quadriceps (the "kicking" muscles") are responsible for the action called knee extension - the action of kicking.
There are 4 muscles of the quadriceps:

The 4 muscles of the quadriceps join together close the knee to form the patellar tendon (have a look at the first diagram); this tendon then passes over the knee-cap, the patellar, and attaches to the lower leg (called the tibia) at a little bony prominence just below the knee called the tibial tuberosity.
Imagine the muscles contracting, pulling on the tendon which pulls on the lower leg - it causes the kicking action.
Tendonitis is a painful condition caused by tendons that become irritated or inflamed through over-use.
Patellar tendonitis is usually caused by repeated jumping, squats or kicking.
In the case of the 2 clients last weekend, this is exactly what they'd been doing - way too many jumps and squats.
Patellar tendonitis is usually felt just below the knee-cap especially when trying to kneel down or bend the knee.
In really severe cases, there will be swelling just below the kneep-cap and the tendon and quadriceps muscles above the knee can also be affected.
The first thing to do in the case of acute inflammation is to ice the knee:
Ice means a bag of frozen peas, wrapped in a tea-towel applied to your knee for 4 mins at a time; do this at least 4 times throughout the day for a couple of days (7 times a day would really be ideal). Remember to bin the peas afterwards.. don’t give yourself food poisoning by trying to eat them!
After the inflammation has gone down - usually after 48 hours - a good sports & remedial massage therapist will be able to peform some stretches using a technique called soft tissue release.
Some good old fashioned deep tissue massage of the muscles of quadriceps will then help to relieve the tightness there that's built up from over-use.
As ever, if you think I can help, give me a call.
