During the physical exam, your doctor is likely to inspect your knee for swelling, pain, tenderness, warmth and visible bruising and check to see how far you can move your lower leg in different directions, push on or pull the joint to evaluate the integrity of the structures in your knee
In some cases, your doctor might suggest some Imaging tests such as:
· Computerized tomography (CT) scans.
· Magnetic resonance imaging (MRI).
· Lab tests
If your doctor suspects an infection or inflammation, you're likely to have blood tests and sometimes a procedure called arthrocentesis, in which a small amount of fluid is removed from within your knee joint with a needle and sent to a laboratory for analysis.
Treatments will vary, depending upon what exactly is causing your knee pain. Your doctor may prescribe medications to help relieve pain and to treat underlying conditions, such as rheumatoid arthritis or gout.
Strengthening the muscles around your knee will make it more stable. Your doctor may recommend physical therapy or different types of strengthening exercises based on the specific condition that is causing your pain.If you are physically active or practice a sport, you may need exercises to correct movement patterns that may be affecting your knees and to establish good technique during your sport or activity. Exercises to improve your flexibility and balance also are important.
In some cases, your doctor may suggest injecting medications or other substances directly into your joint. Examples include:
· Hyaluronic acid.
· Platelet-rich plasma (PRP).
If you have an injury that may require surgery, it's usually not necessary to have the operation immediately. If you choose to have surgery, your options may include:
· Arthroscopic surgery.
· Partial knee replacement surgery.
· Total knee replacement.
