Background:
We report a rare case of glomus tumor that occurred in the lateral joint of the knee. A 54-year-old man was referred to us with a 3-year history of lateral pain in the left knee and the diagnosis of lateral meniscus injury. Physical examination revealed a small trigger point localized just on the lateral joint space. Magnetic resonance imaging (MRI) showed a very small round mass in the subcutaneous tissue at the level of the lateral joint space.
Treatment:
Excisional biopsy was performed, and the histology was characteristic of a glomus tumor. The patient was asymptomatic immediately after the operation. At the 3-year follow-up after the operation, no recurrence was seen.

Anterior Compartment
The quadriceps femoris, the most visible muscle of the anterior compartment, is integral for leg extension and thigh flexion. It is formed by merging four distinct muscles — the vastus lateralis, vastus medialis, vastus intermedius, and rectus femoris. The quadriceps tendon, a shared tendon of the four quadriceps muscles, is affixed to...
