Comparisons were not made at cycles as the majority of anchors failed before this point Pull-out strength of suture anchors for rotator cuff and Bankart lesion repairs. Statistical analysis Kruskal-Wallis one-way analyses were performed to compare sstryker tensile mechanical properties of the different commercial suture anchors and traditional bone anchor to determine initial variance.
Mechanical properties of all-suture anchors for rotator cuff repair
Placement of all-suture anchors generally involves drilling a small pilot hole into the bone, and subsequently placing suture material in a latent configuration attached to a catheter device, which allows the suture to expand in the cancellous bone under the cortex as the catheter is removed.
Performed experiments, Assisted with data analysis, Co-drafted the paper. Generally speaking, the findings reported in this study are consistent with those reported in the literature. As a result, findings from this study cannot be directly compared with other work, especially where direct axial loading was performed.
With regard to gap formation of the construct, we found that the plastic control anchor had a mean total displacement of In another study, an in vivo canine model developed by Pfeiffer et al 9 compared all-suture with traditional anchors and their findings corroborated with those of this study, reporting that all-suture anchors undergo greater displacement during cyclical loading at ultimate load mean However, over the last decade, a novel fixation technique has emerged.
Although we discuss here load-to-failure and displacement as important mechanical characteristics to define the properties of anchors, these in themselves may be too simplistic to determine the value of implants for RC repair. In the context of traditional anchors, early post-operative anchor movement is a relatively rare complication, reported as 0. The drill is subsequently removed and replaced with the Q-FIX implant inserter which goes into the guide.
Author information Article notes Copyright and License information Disclaimer. Displacement of all-suture anchors as determined by changes in grip-to-grip distance over increasing cycle numbers and eventually to failure.
Kruskal-Wallis one-way analyses were performed to compare the tensile mechanical properties of the different commercial suture anchors and traditional bone anchor to determine initial variance. The JuggerKnot anchor had greatest displacement at 50, and cycles, and at failure, reaching statistical significance over the control at and cycles The relative bio-incompatibility of all-suture anchors could predicate weaker load-to-failure values after long-term implantation.

Results Overall, mean maximum tensile strength values were significantly higher for the traditional anchor Am J Sports Med ; Otherwise, there was no significant variation between displacement values of the anchors. Cyclic loading biomechanical analysis of the pullout strengths stdyker rotator cuff and glenoid anchors: Mean displacement differential values and standard error se mm of tested anchors between 50 cycles and: The aim of this study was to compare the mechanical properties failure load and cyclic displacement and failure stryke of all-suture anchors with those of a traditional suture anchor in iconkx human humeral heads.
The JuggerKnot implant had the greatest increase in displacement between 50 and cycles, with mean displacement of Our study showed greater than previously reported gap formation, and this is likely to be due to the specific experimental set up, though it should be noted that the consistency of the construct design and experimental procedures facilitated comparisons of gap formation in implants tested.
Intra- and inter-donor variation was not determined by bone density, although reasonable attempts, such as utilising a variety of laterality of humeral heads of different aged cadavers in combination with separate anchor brands to ensure matched sample distributions, to control for this were employed. Mechanical properties of all-suture anchors for rotator cuff repair.
It was performed on cadaveric human humeral heads and was not representative of in vivo conditions with regard to temperature and the proximal suture-tendon interface.
All samples were kept hydrated in 0. This limitation of the methodology is somewhat imposed by variations in product design. Additional analysis of displacement was performed to determine changes in displacement differentials after the first 50 cycles to accommodate initial anchor settling. Conclusion We demonstrate decreased failure load, increased total displacement, and variable failure mechanisms in all-suture anchors, compared with traditional anchors designed for rotator cuff repair.
Furthermore, in a complete human cadaveric RC repair model, a standard single-row metal anchor repair demonstrated up to 7. All-suture anchors are increasingly used in rotator cuff repair procedures.
The JuggerKnot anchor did have significantly greater displacement over control anchors at and cycles The awl is removed and the anchor is placed through the guide and, using a mallet, advanced until a positive stop is achieved.
Furthermore, studies have shown the maximum tensile strength of anchors to range from 49 N to 66 N in one paper, 8 to N in another, 5 highlighting the need for a comprehensive evaluation of all commercially available all-suture anchors in comparison with traditional anchors. Designed the study, Performed experiments, Subsequent data analysis, Drafted the paper.
The mean maximum tensile strength value was significantly higher for the traditional anchor Results of the surgical repair of the rotator cuff.
Biomechanical analysis of pullout strengths of rotator cuff and glenoid anchors: Introduction Anchorage of sutures in the repair of rotator cuff RC tears has traditionally made use of large, screw-shaped anchors consisting of either metal or plastic polymer materials to secure sutures into bone.
Anchors tested A review of the literature and a search through the procurement department of our tertiary referral centre hospital was conducted to determine current commercially available all-suture anchors accurate as of Aprilof which four were found.
There are limitations to this study. With the exception of the Q-FIX 4. The maximum pull-out strength values reported are comparable with those of previous studies which have performed similar tests using all-suture anchors, with slight variations in materials and methodology. Thereafter, sutures are unwound from the inserter and the construct is removed. Viscoelastic properties of common suture material used for rotator cuff repair and arthroscopic procedures. Displacement, after initial application strykrr load, was recorded during cyclic loading.
Previous studies have endeavoured to look into the mechanical properties of all-suture anchors and compare these with traditional bone anchors.
