When assessing a client's range of motion, the nurse notes crepitation with movement of the left knee. Which information in the client's history is most likely related to this finding?

A. Knee arthroplasty surgery. A knee replacement may improve joint function and reduce pain, but it is less likely to cause crepitation unless there is implant wear or loosening. Crepitation is more commonly associated with cartilage degeneration rather than past surgical intervention. B. History of a fractured patella. A previous patellar fracture may lead to stiffness or limited range of motion, but it does not typically cause crepitus unless there is residual joint damage or post-traumatic arthritis. C. Needle aspiration of the synovial space. Joint aspiration is used to remove excess fluid in conditions like gout or infections. While it may temporarily reduce swelling, it does not contribute to crepitus, which results from cartilage breakdown rather than fluid accumulation. D. Degenerative disease. Crepitation, or the grating sensation felt during joint movement, is commonly associated with degenerative diseases such as osteoarthritis. The breakdown of cartilage leads to rough joint surfaces, causing friction and noise during movement, making this the most likely cause of the finding.
