Postural hypotension: Feeling lightheaded on standing, having blurry vision and collapsing is most like drop in blood pressure, called postural hypotension. In most cases it does not indicate anything sinister but falls secondary to it can cause injury. Certain blood pressure medications, dehydration due to diarrhoea, vomiting can also result in postural hypotension. See Gp for review if symptoms occur regularly. ...Read more

See your doctor and: After a complete history and physical, if there is no sure diagnosis, ask for either a knee MRI or a consult with a sports medicine physician or an orthopedic surgeon.

Inflammed tendon, or: Pain below the patella is commonly (not always) due to inflammation of the patella tendon, aka "jumper's knee". Chondromalacia/arthritis is also a consideration. Typical treatment options consist of rice, antiinflammatories, physical therapy, counterbrace supports, massage, injections. Your orthopedic physician can provide a more accurate diagnosis with a physical exam and possible x-ray. ...Read more

Knee cracking pain only going upstairs, knee collapsed, crunching sounds, lack of extension patella not tracking as per physio what is the cause?

Knee cracking pain only going upstairs, knee collapsed, crunching sounds, lack of extension patella not tracking as per physio what is the cause?

Patellofemoral issue: The likely cause of your condition is that the knee cap is getting off track when you bend your knee due to lack of quad muscle strength (VMO). This causes the knee cap to track laterally when you bend your knee and leads to cartilage irritation (chondromalacia) under the knee cap which can cause aching and produce crunching sounds. Keep working with your physio to correct the problem. ...Read more

I have transverse myelitis, I have been doing physio for 14 months, but when I walk my right knee just collapses forward as soon as I weight-bare why?

I have transverse myelitis, I have been doing physio for 14 months, but when I walk my right knee just collapses forward as soon as I weight-bare why?

UMN weakness: Upper motor neuron weakness from inflammation injury of the spine (transverse myelitis) typically causes spastic weakness: even though the muscles are tight and may at times cramp or spasm, they are still weak b/c the brain lost control over voluntary movement of affected muscles. Ask about adding neuromuscular electrical stimulator (nmes) to rehab routine. Good luck! ...Read more

Left knee felt like it dislocated when I exited shower recently and collapsed painfully. I did have surgery for torn meniscus years back. What was it?

I have ehlers-danlos syndrome hypermobility type. My arches collapse, ankles roll in and knees go backwards. Could AFOs help stabilize my bendy joints?

I have ehlers-danlos syndrome hypermobility type. My arches collapse, ankles roll in and knees go backwards. Could AFOs help stabilize my bendy joints?

Yes: There are many people afflicted with ehlers danlos who speak highly of smo (short AFO for feet) and other AFO to help stabilize. These are costly and a long project but certainly worth going to an orthotist to look in to. ...Read more

Comments: I am guessing your concern focuses on prognosis, and hopefully, you are in a therapeutic program involving physical therapy and bracing. Even passive exercise will provide value. Your described reactions are to be expected at this point, and expect some further healing over the next 6-7 months. The ultimate degree of recovery cannot clearly be predicted, but keep working. All the best for you. ...Read more
