Question
A 20-year-old woman undergoes an inside-out meniscus repair. Two weeks after surgery, the patient reports constant burning in the knee and proximal leg. What is the most likely diagnosis:
1- Deep venous thrombosis
2- Failed meniscal repair
3- Arteriovenous malformation
4- Saphenous nerve injury
5- Popliteal nerve injury
Figures
Answer (click for answer)
Correct Answer: 4- Saphenous nerve injury
The report of constant burning pain is always suspicious for nerve injury. Austin and Sherman in the referenced article reported their complications from 101 consecutive arthroscopic meniscal repairs. The most common complication was saphenous neuropathy, which occurred in 7% of cases. Most of these resolved within four months. There was a 1% incidence of peroneal nerve injury.
