What Causes Medial Knee Pain?
Runner’s knee may be triggered by different conditions and risk factors.
Often more than one is involved.
These include:
Improper form while running can increase the risk of injury.
This could suggest that running using shorter strides is associated with a lower risk of injury.
The study was performed on both outdoor surfaces and indoor equipment like treadmills.
When you are running or walking, the best position for your knee is directly over your foot.
Sometimes,flat feetcause your lower leg to turn inward.
This can place increased stress on the inner part of the knee joint, causing pain.
What Is Patellofemoral Pain Syndrome?
Patellofemoral pain syndrome is the same thing as runner’s knee.
It is considered a disorder of thepatellofemoral joint.
How Is Medial Knee Pain Diagnosed?
Diagnosing inner knee pain can be challenging because there may not be one clear cause.
In many cases, multiple conditions contribute to your pain.
Figuring out which are involved can take time.
During the physical examination for inner knee pain, your healthcare provider will assess various structures around your knee.
They range from simple home remedies to more invasive medical procedures.
It’s best to stop running until your pain is gone or you have a healthcare provider’s clearance.
They may refer you to anorthopedic surgeonwho specializes in bone and joint problems.
Most people who have arthroscopic knee surgery return to pain-free walking within four to six weeks.
Severe cases may require prescription painkillers, physical therapy, cortisone knee injections, viscosupplementation, or surgery.
They may start with conservative treatments, like a referral to physical therapy, to address the pain.
