Thanks for your query.
From the brief details, it appears that you husband has been suffering from osteoarthritis
, with acute pain and present problems precipitated by breaking off of a small piece of cartilage
in the joint (which causes osteoarthritis).
Other possibility is avulsion of a tendon around the knee joint.
Get a CT scan
of the knee to establish the exact cause. Rest to the knee joint, along with a short course of anti-inflammatory pain-killers, such as ibuprofen
combination will help.
Consult your doctor and apprise him of my opinion. I am certain that he agree with me, order required tests, and- based on the reports- will prescribe suitable treatment as advised.
