How is a meniscal root repair performed?
Traditional repair treatment for a meniscal root injury involves a partial meniscectomy, this option may be best for some patients. In general surgeons would like to preserve as much meniscus tissue as possible with meniscal root repair procedures. There are four meniscal roots tear treatment strategies:
- Repair with pull-out tunnel technique
- Repair with suture anchors
- Repair with side-to-side sutures
- Partial meniscectomy.
Repair with the pull-out tunnel technique is reserved for when the meniscal root is torn from the tibia. One or two small tunnels are drilled through the tibial bone to area of the native root insertion of the meniscus. Non-absorbable sutures or stitches are used to secure the root back onto the bone. Special screws, pull-out buttons or bone bridges may be used to cinch down the sutures.
Repair with the suture anchor method involves the placement of small pledget or hook implant near the native meniscal root insertion. This implant usually is loaded with sutures which in turn facilitate a repair by allowing the surgeon to reattach the meniscus to its normal insertion point on the tibia.
Repair with side-to-side technique refers to the use of simple stitches to sew a split meniscus back together. The side to side technique of stitching the root is typically done for complex meniscal root tear injuries or when the root is torn too close to the tibia.
A partial meniscectomy involves removing a subsection of the meniscus (the area of the tear) as a means of relieving pain in affected patients.
