what is suprapatellar osteophyte-it was found in my xray of the knee?

Answer:

"Supra" means "above".
"Patella" is the medical term for "knee cap".
"Osteophyte" means a bone spur, or a small irregular outgrowth of bone. (imagine the thorns on a rose stem, or the spurs that horseriders wear).

So a "suprapatellar osteophyte" is a small bone spur above your knee cap. Osteophytes are common in arthritis.
