[A woman with knee locking after a partial knee arthroplasty]

Area of Science:

• Orthopedic Surgery
• Biomedical Engineering

Background:

• Partial knee arthroplasty is a common procedure for knee osteoarthritis.
• Complications can arise, necessitating further intervention.

Observation:

• A 57-year-old female patient reported knee locking and lateral knee pain post-procedure.
• Symptoms were indicative of a potential mechanical obstruction or inflammatory response.

Findings:

• Knee arthroscopy revealed two loose cement particles.
• These particles were successfully identified and removed during the procedure.

Implications:

• Loose cement particles are a potential cause of persistent symptoms after knee arthroplasty.
• Arthroscopic removal of foreign bodies can be an effective treatment for specific post-arthroplasty complications.
