Background
At present, most repair techniques for meniscal tears fix the meniscus directly over the capsule. This changes the normal anatomy and biomechanics and limits the activity of the meniscus during motion. We introduce an arthroscopic repair technique by suturing the true meniscus tissue without the capsule and subcutaneous tissue.
Methods
After confirmation of a tear, a custom-designed meniscal repair needle first penetrates percutaneously, crossing the capsular portion and the torn meniscus, and exits from the femoral surface of one side of the torn meniscus. Then a No. 2 PDS suture is passed through the needle and retrieved through the arthroscopy portal. Next, the needle is withdrawn to the synovial margin of the meniscus and is reinserted, exiting the femoral surface of the other side of the torn meniscus. The suture is pulled out through the same portal with a grasper. Finally, arthroscopic knotting is performed.
Results
We had 149 cases of meniscal tears repaired with this outside-in transfer all-inside technique since July 2016.
Conclusions
It is a simple, minimally invasive, and economical procedure that is appropriate for most parts of the meniscus except the posterior horn of the lateral meniscus, and it can be used to fix torn meniscus tissue firmly while also preserving the inherent activity of the meniscus.
