“…From a clinical point of view, the results of the present study are broadly in agreement with other published studies of arthroscopic stabilization with absorbable anchors [6,7], although the relatively high rate of recurrent instability (14%) remains a concern. This may partly be a result of the high proportion of athletes returning to contact sport (chiefly rugby union) in this series and thereby sustaining a re‐injury.…”

BackgroundWe investigated the reconstitution of the glenoid bone after degradation of absorbable knotless suture anchors used for labral repair.Methods Arthroscopic labral repairs performed on 59 shoulders in 55 patients by a single surgeon using knotless poly-L-lactic acid suture anchors were reviewed at a mean of 46.5 months. Computed tomographic scans of the operated shoulder were reviewed by two independent radiologists for the number of drill holes present, as well as the amount of bony reconstitution and the presence of osteoarthritis. ResultsOne hundred and ninety anchors were placed and both radiologists counted 185 drill holes (97%). Agreement between the radiologists was high (kappa = 0.96). The majority of holes had partial bony ingrowth (69% to 71%) and osteolysis was infrequent (6%). The prevalence of degenerative joint disease was 7% to 8%.Conclusions Biodegradable suture anchors are a viable option for labral fixation during arthroscopic shoulder stabilization but, in most cases, the drillholes are not fully replaced with bone and may enlarge, although the effect on clinical outcome is uncertain.

“…Barber et al [1] gives a good outline of the range of geometric anchor designs that are most often titanium alloy or stainless steel. However, the use of polymers [1,2], and bioabsorbable or biodegradable anchors [3] is also increasing. The threaded helix has performed well under in vitro static conditions [1,2].…”

Bone anchors (or suture anchors) are used to provide attachment points for sutures to connect tissue such as tendons or ligaments to bone, and work by engaging a threaded portion-sometimes tapered-to the cancellous and/or cortical bone. Such repair is often needed after trauma, or as part of reconstructive surgery. This paper uses the finite element method to compare the pullout characteristics of one common type of bone anchor in different cancellous bone structures. Finite element models are created by using computed tomography (CT) scans of cancellous bone and building computer-aided design (CAD) models to define the cancellous bone geometry. Orthopedic surgeons will sometimes remove parts of the cortical shell and this paper also examines the mechanical effects of decortication. Furthermore, the importance of the connection between anchor and cortical layer is examined. One of the key outcomes from the model is that the coefficient of friction between bone and anchor determines potential mechanisms of pullout. The stiffness of anchors and the effect of the cortical layer are presented for different pullout angles to obtain the theoretical response. The results show the detailed modeling that includes the micro-architecture of the cancellous bone is necessary to capture the large variations that can exist.

“…They demonstrated that decreased failure load, increased total displacement, and variable failure mechanisms in all-suture anchors and also concluded that their findings will aid the surgeons choice of implant, in the context of the clinical scenario (14). In addition, compared to other conventional suture anchors, (9). In the present study, despite the short follow-up time (23.71±3.65 months in group 1 and 21.87±4.39 months in group 2), our outcomes were concordant with previously published reports.…”

“…Over the past three decades, suture anchors (variations in size and suture types, metal or plastic polymer) have been widely used to treat soft tissue pathologies and other musculoskeletal disorders, such as repair of bankart lesions, biceps tenodesis, acromioclavicular joint dislocation reconstruction, deltoid repair and capsulolabral repair (8). However, despite good to excellent outcomes in most studies, there are no gold standard guidelines described for suture anchors use in arthroscopic labral repair (9,(16)(17)(18)(19). In our experience, the present study demonstrated that arthroscopic labral repair of anterior shoulder instability with this all-soft suture anchors was associated with good clinical and functional outcomes, similar to the conventional suture metal anchor.…”

Aim: To compare the clinical results after arthroscopic bankart repair with all-soft suture anchor and conventional metal anchor in physically active patients with traumatic anterior shoulder instability. Material and Methods: A total of 32 patients who met eligibility criteria were included between 2016 and 2017 years, for arthroscopic bankart repair in a single orthopedic department. The patients were examined into 2 groups as 17 underwent repair with 1.8 mm all-suture anchor with 2 (5 metric) Hi-Fi® sutures (Y-knot® flex, Conmed, USA) (group 1), and 15 underwent repair with conventional titanium 3.5 mm Suture Anchors with two preloaded ultrabraid sutures (TWINFIX, Smith & Nephew) (group 2). Clinical and functional outcomes were assessed pretreatment, and final follow-up using the American shoulder and Elbow surgeons (ASES) score and the ROWE score. Results: The mean ASES score increased significantly in group 1 from 35.62±8.46 to 88.86±6.23 (p=0.0001) and had increased significantly in group 2 from 41.15±14.51 to 91.15±7.54 (p=0.0001). The mean ROWE score had increased significantly in group 1 from 48.82±11.25 to 85.00±10.00 (p=0.0001) and had significantly increased in group 2 from 45.67±9.61 to 87.67±10.15 (p=0.0001). There was no significant difference between the mean ASES scores of group 1 and group 2 (p=0.192, p=0.353), and also no significant difference between the mean ROWE scores of group 1 and group 2 (p=0.404, p=0.461) at pretreatment and final follow-up respectively. Conclusion: Arthroscopic bankart repair with an all-soft suture anchor demonstrated comparable clinical and functional results as the conventional metal suture anchor at short term follow-up.
