Summary
Two patients experienced persistent anterior ankle pain after injury. Surgical removal of a fibrous band resolved the impingement, leading to pain-free recovery within one year.
Area of Science:
- Orthopedic surgery
- Sports medicine
- Anatomy
Background:
- Ankle injuries, such as ankle distortion, can lead to chronic pain syndromes.
- Anterior ankle impingement is a common cause of persistent pain following ankle trauma.
- Intra-articular abnormalities may contribute to unresolved symptoms.
Observation:
- Two patients presented with persistent anterior ankle pain after an ankle distortion.
- A unique web-like intra-articular fibrous band was identified within the ankle joint in both cases.
- This fibrous band was surgically resected.
Findings:
- Resection of the intra-articular fibrous band effectively treated the anterior ankle impingement.
- Both patients reported complete resolution of pain.
- Pain-free status was maintained at a 1-year follow-up.
Implications:
- This case report highlights a potential, previously under-recognized cause of persistent anterior ankle pain.
- Surgical intervention for intra-articular fibrous bands can provide a successful treatment option.
- Further research may elucidate the prevalence and etiology of such bands in post-traumatic ankle pain.

01:10Ankle Joint
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...
