OBJECTIVE: Ankle sprain is the most frequently occurring acute injury in tennis, accounting for 20-25% of all injuries. In the current paper, we assess the cause of ankle sprain and suggest possibilities to be considered during diagnosis.
METHODS: We assessed a professional tennis player with a partial tear of the long peroneal tendon after an ankle sprain by physical exam, X-ray and MRI.
RESULTS: Conservative treatment by means of soft cast and propriocepsis training led to full recovery.
CONCLUSION: Peroneal tendon disorders must be part of the differential diagnosis after ankle sprain in the professional athlete.
