Prepatellar bursitis: Its difficult to say without examining you or without further info. When patients complain of a squishy knee especially at the front it often refers to prepatellar bursitis. This is an inflamation of the bursa or protective sac anterior to your knee cap. It can become inflammed when aggravated by hitting it or kneeling on it. Rx is nsaids, padding, possible inj- see your orthopedist.
