Pearls and Pitfalls of the Procedure

Pearls	Pitfalls
Careful evaluation of the meniscal volume should be performed to penetrate the reduction suture.	Improper suture management, resulting in suture entanglement and difficult suture tying
Enough tension to reduce the parrot beak with reduction suture	Inadequate fibrin clot introduction into the tear
Rapid and strong aspiration of bone marrow is needed owing to easy coagulation.	Inadequate suture knot tension resulting in gapped repair
Tourniquet is not necessary during aspiration.	Strong aspiration is needed for enough amount of bone marrow aspirate.
Immediate exogenous fibrin clot development to be performed on the back table	Sometimes slow aspiration causes bone marrow to become coagulated and no longer can be aspirated.
The blood is stirred in the sterile glass container dish within 10 min.	There are individual differences in the amount of the fibrin clot.
Inside-out technique is the easiest for placement of the fibrin clot.	Inadequate chondral clearance for suture passing may result in iatrogenic chondral injury.
During meniscal repair with inside-out technique, reduction suture should always be tensioned to maintain the anatomical position.	Careful retraction should be performed to protect the neurovascular structures behind the knee during inside-out technique.
Reduction suture is tied at the capsule following finishing repair with inside-out technique.	Inside-out technique is performed with a thin needle, so not all inside-out technique devices are recommended, since the parrot beak portion is considered thin and weak.
	Placement of more sutures is required for increased stability.
