Positive first response from medical community...

'Water-on-the-knee' should really probably be called 'fluid-in-the-knee'. The fluid is not just water, and the fluid it is IN the knee not ON it. 

The knee joint cavity is lined with a membrane that produces lubricating fluid to help the smooth movement of the knee in bending and straightening. This fluid is normally like egg white, and the knee cavity normally contains a little under a teaspoon (less than 3.5 millilitres) of this fluid. It is called 'synovial fluid' and the membrane that produces the fluid is called 'the synovium' or the 'synovial membrane'.

If you read through the reference given in the previous chapter, you will know by now that there are a number of possible surgical techniques that may benefit someone with joint cartilage damage in the knee. To help surgeons decide which procedure to do, a number of flowcharts (or 'algorithms') have been developed. The surgeon can estimate the depth of the damage and the width of the damaged area, and ask the patient questions about their lifestyle and age. Then by referring to the flowchart, the surgeon will have a fairly good idea of what surgery is likely to benefit the patient.

There are so many sites on the internet now that doing a search can be really frustrating. Especially when up comes dozens of sites with the same content or, even worse, sites with nothing but ads on them. Also one has to comb through the content to separate out the type of content a patient can understand from the type of content aimed at surgeons.

So I have put together two search engines (using a Google application) especially for you. One has patient content and the other is content for doctors. There should be very little rubbish coming up when you search.

Below is a summary of my second month in physical therapy after reconstruction of my patellar tendon by Dr. Noyes. Again, I would like to express my sincere gratitude to the staff at Cincinnati SportsMedicine (CSM) for the treatment that I received. Their dedication, patience, and endless words of encouragement were greatly appreciated.
