Advantages and Disadvantages of All-Inside Zip Repair

Advantages	Disadvantages
•Technically more straightforward and easily reproducible.	•Risk of cartilage injury in the tight lateral compartment to the posterior aspect of femoral condyles.
•Scorpion and SutureLasso techniques are all-inside, low-cost, nonimplant surgeries.	•Demands special instruments like Knee Scorpion and SutureLasso hook passer.
•Multiple sutures can be used in Scorpion and SutureLasso methods.	•May need an additional incision.
•Less chances of injury to posterior structures in Scorpion and SutureLasso hook method.	•Chances of neurovascular injury in all inside devices.
•Less associated morbidity as compared with inside-out.	•Regular posterolateral portal essential for zip identification and repair.
•Using posterolateral portals allows better visualization of the extent of the tear, hidden lesions, better maneuvering, and repair.	•Chances of cut-through of sutures if poor tissue quality.
•High healing rates.	•Failure to heal or inappropriate rehabilitation can lead to changes in knee biomechanics.
•Strong repair construct.	•Need to put all-inside devices on the top and bottom of the surface, thereby increasing the cost.
•Complex tears also can be managed with the lasso hook and Scorpion method.
