Just had my six-month follow-up x-ray for appointment with surgeon tomorrow. Does anyone know what the following means, particularly how serious or not serious the patellar subluxation is? For several months I cannot lift my leg below the knee; that is, push my leg from the knee down outward. In a previous visit the surgeon told me it was caused by muscle weakness, but I can still only lift it about an inch. Thank you.
FINDINGS:
Alignment: Interval abnormal lateral subluxation of the patella relative to the metallic trochlear prosthesis. Surgical defect of the patella remains. No fracture of the native patella.
Bones: No acute fracture or aggressive osseous lesion.
Joint Space: Total left knee arthroplasty. No evidence for hardware failure or loosening.
Soft Tissue: No chondrocalcinosis or significant suprapatellar joint effusion appreciated.
IMPRESSION:
1. Interval abnormal lateral subluxation of the patella relative to the metallic trochlear prosthesis. Surgical defect of the patella remains. No fracture of the native patella.
