Osteonecrosis of the femoral
condyle is known as an uncommon complication after
arthroscopic meniscectomy. The lesion of
osteonecrosis can be irreversible, thus early
detection of the
disease is crucial for
treatment. A 50-year-old
male patient without known
risk factors of
osteonecrosis developed increasing
knee pain after arthroscopic partial
meniscectomy.
Magnetic resonance imaging showed rapid progression of
osteonecrosis of the medial femoral
condyle.
Unicompartmental knee arthroplasty was performed after 9 months of
conservative therapy. The
patient is now free from
pain during daily activities. It might be important to remind that if the
patient's
pain after arthroscopic partial
meniscectomy is severe than expected, clinical doctors should pay
attention to the possibility of ongoing
osteonecrosis of the femoral
condyle.
