Patellar Osteonecrosis Following Knee Arthroscopy.

Area of Science:

• Orthopedics
• Sports Medicine
• Surgical Innovation

Background:

• Knee osteonecrosis is a recognized complication following arthroplasty.
• Patellar osteonecrosis is exceptionally rare.

Observation:

• A 50-year-old female athlete developed patellar osteonecrosis three months post-knee arthroscopy.
• The patient underwent arthroscopy for a medial meniscus tear.

Findings:

• This is the first reported case of patellar osteonecrosis secondary to knee arthroscopy.
• The condition followed a partial medial meniscectomy.

Implications:

• Highlights the potential risk of patellar osteonecrosis after knee arthroscopy.
• Emphasizes the importance of protecting the anterior fat pad's vascular supply during arthroscopic surgery.
