This standard technique includes fixation through transosseous tunnels in the patella. It is secured to the patella with 2 SwiveLock anchors. 2010 Jan. 38 (1):171-5. . James M. Paci, MD, (Stony Brook, NY) demonstrates a new technique for proximal patellar tendon repair using SwiveLock ® anchors and FiberTape ® suture. Acute patellar tendon rupture: A new surgical technique. Tendon Preparation. Several techniques have been reported, including end-to-end repair and single-row suture anchor constructs. At the conclusion of the fixation, I was able to flex the knee to 70 degrees without any gap formation occurring. Design: Controlled laboratory study. curette bone to get bleeding surface on patella. Anchors. In the experimental group, specimens were pretensioned with a simulated active concentric quadriceps contraction with cycling of the knee 10 times from 90 degrees to 5 degrees of flexion. Gap formation in transpatellar patellar tendon repair: pretensioning Krackow sutures versus standard repair in a cadaver model. Postfixation loosening within the Krackow stitch–tendon construct may be associated with gap formation in patellar tendon repair. Arthroscopy. Am J Sports Med. #2 to #5 non-absorbable suture Krakow stitches x2 into tendon (4 strands exiting tendon) Now, the lower wall of the patellar was exposed, posterior to the patellar side. 2000 Nov. 16 (8):869-70. . Patellar tendon ruptures are rare injuries in young athletes, resulting in disruption of the extensor mechanism, and require surgery for functional recovery. sharply clean off edges of tendon and inferior pole of patella. The strength of these repairs has been questioned, and they are commonly augmented. The tails of the sutures were in the midline. The use of suture anchor fixation has several advantages over the standard approach, including less dissection, decreased surgical time, more accurate suture … A 2 mm fiber tape x4 was used to put Krackow suture, one on either side on the proximal and distal end of the patellar. 1b) and then chose a simple suturing ligament with the Krackow suture technique , and drilled under the inferior pole of the patella to form 4 bone tunnels and cross-stitching. Standard manual traction was used in all specimens to remove Krackow stitch slack. Hypothesis Pretensioning the Krackow stitch–tendon construct decreases postfixation gap formation in transpatellar patellar tendon repair. Fixation. METHODS: Patellar tendon rupture was simulated in 8 pairs of cadaveric knees. Suture and Knotless SwiveLock. Suture anchor repair of quad tendon and patella tendon (n=6) Transosseous tunnel repair of quadriceps tendon (n=6) ... krackow stitches placed along the medial, central, and lateral aspect of the tendon, and 3 horizontal mattress stitches placed 5 ... except for one sample was a mid-substance failure of the quadriceps tendon. Ong BC, Sherman O. 3 drill holes from inferior pole to superior pole of patella with 2.0mm drill. Therefore, we performed quadriceps tendon V-Y quadricepsplasty to restore the patellar tendon (Fig. Methods: Cadavers had a recreated patellar tendon rupture by dissecting the patellar tendon off of the inferior pole of the patella in 8 pairs of cadaveric knees. Failure of this repair technique can result from Elastin, proteoglycan, ... Krackow stitches,12-14 suture anchors,15,16 and augmentation to reduce tension placed on the suture.17 Although the gold standard of primary repair for Background Patellar tendon ruptures commonly are repaired using transosseous patellar drill tunnels with modified-Krackow sutures in the patellar tendon. Suture repair of the ruptured patellar tendon is the treatment of choice for patients requiring operative management. ®. A Krackow stitch pattern is created with the FiberTape suture. The patellar tendon consists of 90% and less than 10% of types 1 and 3 collagens, respectively. Objective: To determine if pretensioning the Krackow stitch in a patellar tendon would decrease gap formation in transpate llar tendon repairs. In order to get further purchase of the tendon, a free needle was utilized, and the FiberWire suture from each of the distal PushLocks was used to perform a Krackow stitch to get good fixation. Krushinski EM, Parks BG, Hinton RY. This simple suture technique has been associated with failure rates and poor clinical outcomes in a modest proportion of patients.
