Hi, thanks for writing to HCM.
Any
injury to the knee joint with persistent pain, swelling or limitation of motion needs evaluation to rule out any intraarticular pathology.
I suspect either you could have injured
MENISCUS or CRUCIATE LIGAMENTS inside the knee joint.
You need
MRI scan to diagnose either of the above injuries.
Temporary management for knee injuries is as follows -
* activity modification by avoiding impact sports which causes more strain on the knee joint
* using an elastic compression bandage to reduce the swelling
* Ice packing to alleviate the pain
*
Physiotherapy to strengthen the quadriceps muscle
Consult an orthopedic surgeon for a detailed workup and management.
Hope this information is helpful. Good day
