Are there different degrees to patella tendonitis? Mine seems almost all cleared up after 2weeks...Using rice method

Sort of. Acute & chronic. Short healing period, or minor, & longer healing, chronic, major. It's the best i can do.
No. Patellar tendinitis refers to inflammation of the patellar tendon that attaches the patella (kneecap) to the tibia (shin bone). There is only one type of patellar tendinitis, but the severity of the tendinitis can certainly vary patient to patient. Sounds like your case was relatively mild. Rec continuing with rice treatment as you gradually resume regular exercises and activities.
