Ultrasound-Guided Anterior Cruciate Ligament Decompression for Mucoid Degeneration

Ultrasound-guided anterior cruciate ligament (ACL) decompression is a minimally invasive procedure used to treat mucoid degeneration of the ACL, characterized by the accumulation of mucoid material within the ligament leading to ligament swelling resulting in knee pain and restricted motion.

Mucoid degeneration of ACL is evaluated on MRI and presence, location and size of ganglion cysts if any, are assessed.

By using real-time ultrasound guidance, the ACL is precisely targeted to aspirate the gelatinous material from ganglion cysts and decompress the ligament, relieving symptoms while preserving ACL function.

It is usually combined with intraarticular injection of steroid and local anaesthetic for pain relief.

The procedure is performed under local anaesthesia, usually on outpatient basis.

This procedure is excellent for patients with symptomatic mucoid degeneration who experience persistent knee pain or limited range of motion despite conservative treatments like physical therapy or analgesics.
