A novel and efficient surgical knotting technique for high-tension closures.

ABSTRACT:

Background

The closure of high-tension incisions without any assistance can be difficult and challenging for surgeons. A common practice is to fix the first knot with a clamp and then tie a reverse locking knot; however, this practice has certain disadvantages. The aim of this study was to introduce a novel and efficient surgical knotting technique with various advantages.

Methods

The two knotting methods used in this study were the absorbable braided suture where the first suture was fixed with a clamp (with assistance) and the SH-9Hospital knotting technique (without assistance) applied on the smooth surface of a cylinder. Mechanical testing was performed using a universal material testing machine. The load-elongation curve and ultimate tensile load (UTL) were recorded.

Results

The mean knotting time was 36.40±1.50 s (range, 32-41 s) and 24.80±1.16 s (range, 21-28 s) in the clamp and SH-9Hosptial groups, respectively. The mean UTL was 120.8±10.14 N (range, 81.11-136.55 N)and 126.5±6.29 N (range, 104.88-139.56 N) in the clamp and SH-9Hospital groups, respectively. The knot strength of the SH-9Hospital technique was not inferior to traditional clinical practice.

Conclusions

The SH-9Hospital knotting technique was a secure, convenient, and efficient method for high-tension closure.

Project description:Revision patella tendon repairs are technically challenging, and to this point there is no gold standard with regard to treatment. Understanding how the surgeon previously repaired the tendon can be of use in the revision case. This includes a repair using anchor fixation in tunnels from the primary procedure, allograft augmentation under the retinacular layer, and application of a bioinductive implant. Technique Video Video 1 (0-0:05): Title. Video 2. (0:06-0:07): Disclosures. Video 3. (0:08-0:30): Intraoperative setup that includes both legs prepped in. Ensure the operative extremity is on a bone foam, has a tourniquet on, and x-ray machine is in the room. Video 4. (0:31-0:49): It’s critical to evaluate the primary repair. Sutures from the primary repair are seen extending from the inferior pole of the patella into the proximal portion of the tendon. Video 5. (0:50-1:10): This is a critical step in the procedure. Evaluates the patella bone tunnels from the primary repair. This needs to be thoroughly evaluated to determine if they can be used for anchor placement in the revision setting. Video 6. (1:11-1:24): Running locking sutures are placed within in the proximal aspect of the tendon. This suture will be anchored into the inferior pole of the patella using the old bone tunnels. Video 7. (2:12-2:37): Anchors are placed into the inferior pole of the patella using the old bone tunnels. The anchors are loaded using suture that was placed in the tendon. The allograft augmentation path in the retinacular layer is also viewed and showed being tied at the superior pole of the patella. Video 8. (2:38-2:52): Anchors placed within the inferior pole of the patella and the augment path under the retinacular layer. The yellow dotted layer is the path of the augment. Video 9. (1:25-1:40): A guide pin in the tibial tubercle in preparation for the allograft augmentation. This guide pin will be over-reamed. Video 10. (1:41-1:56): The allograft augment is placed through the tunnel and slide proximally. Video 11. (1:57-2:11): The graft is then placed under the retinacular layer. This is passed to the superior pole of the patella. Video 12. (2:53-3:10): Placement of the bioinductive implant over the portion of the tear.
