Knee pain: If the hamstrings are tight, then every time you exstend your lower leg you have to fight against the tight hamstrings. This brings the knee cap hard againt the lower portion of the thigh and its normal groove. It too much irritation a small bit of cartilage on the back of the knee cap can fall off and the float in the joint itself. If it gets pinched as you bear weight, the knee will give way!

Internal knee: Consider internal knee problems besides the hamstrings. There can be a torn cartilage, a joint mouse, ligament or tendon issues. You will be checked to see if you have a knee effusion (fluid inside the knee), instability of the knee supporting structures, locking or you knee on examination. Imaging such as x-ray, ultrsound or MRI will look for structural problems.

Several: There are several conditons that can cause the feeling that the knee "slips out of place". Meniscal tears, ligament injuries and patellar instability are three of the most common possibilities. It is time to seek an orthopaedic evaluation. A thorough history and exam may provide the answer, but aditional studies such as an MRI may also be helpful if needed.
