The Effect of Centralization on Medial Meniscal Extrusion for Medial Meniscus Posterior Root Tear Repair

The Effect of Centralization on Medial Meniscal Extrusion for Medial Meniscus Posterior Root Tear Repair

The purpose of this research is to determine if meniscus root repair with or without centralization will have an impact on postoperative pain, function, activity levels, patient satisfaction, and incidence of revision meniscus surgery.

Inclusion Criteria:

• Type 2 Medial Meniscus Posterior Root Tear demonstrated on MRI
• Notable extrusion (>3 mm) on preoperative MRI

• Varus thrust while weightbearing
• Grade 3 bipolar medial compartment changes (isolated grade 3 changes on single articular surface with ≤ grade 2 changes on the opposing surface remains eligible)
• Previous surgery of the affected knee
• Associated fractures requiring surgery
• Concurrent Vascular injuries
• Hypermobility/Ehlers-Danlos Syndrome
