Thanks for posting your query.
Inability to bend the knee while walking is suggestive of osteoarthritic changes in the knee. While weight bearing, the joint space decreases and it becomes painful for the knee to move due to reduced lubricating agents in the joint.
In the non weight bearing position, the joint space is slightly more thus making the movement easier.
You can take mild pain killers, calcium supplements and get some lubricating agents like glucosamine or chondroitin sulfate prescribed from your orthopedician after an examination.
I hope this answers your query.
In case you have additional questions or doubts, you can forward them to me, and I shall be glad to help you out.
Please accept my answer in case you do not have further queries.
Wishing you good health.
Dr. Praveen Tayal.
