Knee pain when bending my knee

Hi,
A few years ago I was struggling with a problem with my SI joint as well as my left knee, I got given a few stretches to do which have not really helped but the pain is manageable.
At the same time I was struggling with my left knee, so I mentioned it to he physio while I was there they told me it was a cartilage problem where there is a little bit of cartilage sticking out and it will were off and I will be okay again.
This does not seem to have happened and I am concerned that I am not doing what I need to be doing to get going again.
Generally my knee does not hurt but if I go for a jog start getting pain on the right hand side of the knee , to the right hand side of the kneecap and end up limping by the time I get home. After this my knee hurts or a couple of days and stiffens up when inactive.Last week also started getting a sharp stabbing pain behind my leg in the lower knee area and I had to put my knee strap on and take pain killers, after a few hour it will settle down.
The other thing that causes pain is over bending my knee for example if I am stood on something reasonably high and try to get down and in the process bend my knee too much, this can hurt so much I have to sit down for a while.
Can anyone offer any advice?
Thanks,

Hello, i think you have medial meniscus injury, you should see orthopedic surgeon.
if it was treatable conservatively you should see a physio to make strengthening exercises plan.

The pain behind the knee might be a baker's cyst. Do you feel a lump at all?

Hi Knee pain,

The idea of referred pain is now apparently old-fashioned.

But referred pain is very common.
You mentioned a previous Sacroiliac (S/I) joint problem. The most common referred pain from the S/I joints is groin pain.

But S/I problems are invariably associated with lower back problems, usually L4,5,S1,2. Leg symptoms are frequent from this area.

In my experience anterior quadriceps pain and medial knee pain are from T12, L1 and 2.
Hamstring, posterior knee, calf and foot pain are often / usually from L5, S1, 2, 3.

"Excessive" activity will aggravate all of these whilst sitting in deep seats and prolonged standing will always make things worse.

So treatment has to be to the areas shown above. Treating the symptoms can give you short term relief only.

Good luck.
