FNB stands for Femoral Nerve Block, a pain-control method used during or after knee arthroscopy, ACL surgery and meniscus treatment. An anaesthetist injects local anaesthetic near the femoral nerve to reduce pain around the knee and front of the thigh.

FNB may improve comfort and reduce the need for strong pain medicines. However, it can temporarily weaken the thigh muscles, so the orthopaedic department and anaesthesia team must decide whether it is suitable.

A trusted orthopaedic hospital should provide arthroscopy, imaging and physiotherapy facilities. Patients comparing the best orthopaedic hospitals, a reliable bone hospital should consider medical experience, safety and rehabilitation support.

Aditya Hospital in Rewari provides orthopaedic care for ACL tears, meniscus injuries and other sports-related joint conditions.

Conclusion: FNB can support pain relief after selected arthroscopy procedures, but it should only be used after proper medical evaluation.
