Thank you for contacting ask the doctor.
Knee injury could be a vast category to dicuss. This could be either a patellar fracture/dislocation/ tendon tears/ etc. I recommend a visit to the physician since you have a swelling and fever. Seek treatment immediately if you see any of the following signs after a knee injury:
1. Hearing a popping noise
2. Sever pain and restriction in movement of the knee
3. Swelling at the injury site.
Treatment started with rest, ice, compression and elevation. Physician may prescribe you NSAIDs, physical therapy and immobilization. If there is a need for surgical treatment he would guide you through it. Hope this information was useful.
