Summary
We describe a rare case of knee locking in a young woman caused by an osteochondroma. This benign bone tumor on the proximal tibia presented as an unusual cause of knee joint dysfunction.
Area of Science:
- Orthopedics
- Oncology
- Medical Case Reports
Background:
- Knee locking is a mechanical blockage of the knee joint, often caused by internal derangement.
- Osteochondromas are benign bone tumors that typically arise from the metaphysis of long bones.
Observation:
- A 23-year-old female patient presented with recurrent episodes of knee locking.
- The locking was associated with an osteochondroma located on the medial aspect of the proximal tibia.
Findings:
- The osteochondroma was identified as the causative agent for the knee locking.
- Surgical excision of the osteochondroma resolved the locking symptoms.
Implications:
- This case highlights osteochondromas as a potential, albeit uncommon, cause of knee locking in young adults.
- Early diagnosis and surgical intervention can effectively manage this condition, restoring knee function.
