Clinical Efficacy of Modified Nonmesh Sacral Colpopexy for Pelvic Organ Prolapse

Importance As an increasing number of mesh-related complications have been reported, the availability of nonmesh alternatives becomes crucial for situations where mesh is not desired or unavailable. A new modified procedure of nonmesh laparoscopic sacral colpopexy (LSC) was performed in our department, which used a nonabsorbable polyester suture (Ethibond) combined with uterosacral ligament suspension. Objective The aim of this study was to evaluate the clinical efficacy of the modified procedure in comparison with traditional LSC in patients with pelvic organ prolapse. Methods This retrospective study assessed the treatment outcomes of 60 patients who were underwent LSC with or without mesh from January 2017 to April 2019. Patients were divided into 2 groups based on the presence or absence of mesh during the operation: mesh group (n = 34) and nonmesh group (n = 26). General data, perioperative indexes, postoperative complications, and recurrence rates were comparatively analyzed between 2 groups. Results In perioperative indexes, the nonmesh group exhibited shorter operation time (P < 0.001) and less intraoperative blood loss compared with the mesh group (P = 0.004). There was no significant difference in postoperative indwelling urinary catheter duration (P = 0.425) and hospitalization time (P = 0.827) between the 2 groups. In postoperative complications, the incidence of postoperative complications showed no significant difference between the 2 groups (P > 0.05). No occurrences of mesh exposure and erosion were observed in the mesh group during at least a 2-year follow-up period. In postoperative recurrence, none of the patients in either group experienced prolapse recurrence. Conclusions In comparison with the traditional LSC with mesh, the modified laparoscopic nonmesh sacral colpopexy presents advantages of reduced surgical trauma, less pain, and lower cost. However, a long-term and large sample study is required for evaluating the surgery’s long-term efficacy.

Non-metallic fixation of transverse patella fracture using non-absorbable polyester suture

This study aims to evaluate the functional outcomes for the fixation of transverse patella fracture (TPF) using a transosseous suturing method with a non-absorbable polyester suture. A retrospective case series method was conducted on 37 patients who underwent open reduction and internal fixation using a transosseous suturing technique with a non-absorbable polyester suture at Lower Limb Department, Hospital for Traumatology and Orthopaedics, Ho Chi Minh City, from 1/6/2020 to 1/6/2022. Results showed that the surgery time was 37.43±9.76 minutes; average follow-up time was 8.57±5.35 months. The results of facet joint after surgery and bone healing were 100% (very good and good); bone healing time was 14.22±2.78 weeks; rehabilitation time was 13.84±3.3 weeks; knee function according to Lysholm scale achieved very good and good results with the average score of 97.62±3.7 points; no hardware-related complications in the study. One patient fell again and broke the kneecap; 100% of the patients were satisfied after the treatment, especially with the reason that there was no need for a second surgery to get the instruments. In conclusion, the fixation of TPF using a transosseous suturing method with a non-absorbable polyester suture is safe and effective with no hardware-related complications and does not require a second surgery to instrument collection during the mean follow-up period of 8.57±5.35 months.

A Comparison of the Outcomes of Fiber-Wire® versus Stainless Steel Wire in Transosseous Wiring for Intra-Articular Fractures of the Distal Interphalangeal Joint.

Background: Different surgical techniques have been described for the treatment of intra-articular fractures involving extensor tendon insertion of the distal interphalangeal joint (DIPJ), including acute and chronic bony mallet injuries. We have been using transosseous stainless-steel wire (SSW) in select patients. In 2015, we started using a non-absorbable polyester suture (2-0 Fiber-Wire®, Arthrex, Naples, FL, USA) instead of SSWs. The aim of this study is to compare the outcomes of SSW and Fiber-Wire® (FBW) in transosseous wiring for intra-articular fractures of the DIPJ. Methods: This is a retrospective review of patients who underwent fixation of intra-articular fractures, including extensor tendon insertion of the DIPJ using a transosseous wiring technique, in the period from 2013 to 2018. SSW was used in the period from 2013 to 2014, and FBW was used from 2015 to 2018. Outcomes with regard to age, gender, time to union, range of motion at the DIPJ and complications were recorded and compared between the SSW and FBW groups. Results: Nine patients (mean age: 38 years) underwent fixation with SSW and 10 patients (mean age: 31 years) with FBW. The operative time was significantly lower in the FBW group, and all the fractures united. There were no statistically significant differences between both groups with regard to time to union or range of motion at the DIPJ. Similar complication rates were observed in both groups. Conclusions: The use of FBW in transosseous wiring for intra-articular fractures of the DIPJ can reduce operative time and provide functional results similar to that of SSWs. It can be considered as an alternative fixation technique for difficult intra-articular comminuted fractures of the DIPJ, including acute and chronic bony mallet injuries with joint subluxation. Level of Evidence: Level III (Therapeutic).

Anterior approach ptosis surgery: comparison of absorbable polyglactin sutures and non-absorbable polyester sutures. Does Vicryl stand the test of time?

ABSTRACT Purpose To determine whether the long-term success of ptosis surgery is influenced by the use of absorbable or non-absorbable sutures to advance the levator aponeurosis onto the tarsal plate Methods Multi-centre retrospective comparative study of re-operation rates in primary anterior approach ptosis surgery using absorbable polyglactin sutures (Vicryl) and non-absorbable polyester sutures (Ethibond). The Medisoft audit tool was used to identify all patients who underwent primary ptosis surgery for aponeurotic ptosis, performed by five oculoplastic consultants within a 7-year period, across two NHS Ophthalmology departments. The electronic patient records were reviewed for each patient. Basic demographics, suture material, and post-operative complications were recorded. All patients requiring repeat surgery between the study dates and the present day were recorded, allowing a minimum postoperative period of 3 years and 10 months. Re-operation rates in surgery using absorbable Vicryl sutures and non-absorbable Ethibond sutures were compared using Fisher's exact test. Results Four hundred and fifty-five operations in 330 patients were performed within the study period that met the inclusion and exclusion criteria. Fifty-seven percent of the patients were female, with an average age of 68.8 years. One hundred and sixty-nine operations in 128 patients were performed using absorbable Vicryl sutures. Of these, 22 (13.0%) required repeat operations. Two hundred and eighty-six operations in 202 patients were performed using non-absorbable Ethibond sutures. Of these, 17 (5.9%) required repeat operations. The two-tailed P-value was 0.0143. Conclusion The use of non-absorbable Ethibond sutures to advance the levator aponeurosis onto the tarsal plate in primary ptosis surgery is associated with improved long-term success and reduced need for secondary surgery.

Correction of exotropia and improved adduction by fixation of the anterior encircling fascia to the medial rectus insertion site following myectomy of the four horizontal rectus muscles for infantile nystagmus

Myectomy of the four horizontal rectus muscles for infantile nystagmus syndrome without a null point may improve visual acuity and quality of life. Exotropia and adduction loss are complications of this procedure, although abduction is typically preserved. We investigated whether adduction loss may be rescued by reestablishing the attachment of the anterior intermuscular septum (AIMS) to the globe at the medial rectus insertion. We present 2 cases of exotropia and adduction loss following myectomy and transposition surgery, where the nasal AIMS and the medial rectus insertion site were joined with nonabsorbable polyester suture. Both patients experienced improvements in eye alignment and adduction. Based on radiologic observations of the posterior displacement of the pulley, or posterior intermuscular septum (PIMS), with medial rectus contraction, we hypothesize that adduction and alignment were improved by providing an anterior site of action for the posterior movement of the PIMS.

Exotropic heavy eye syndrome in unilateral high axial myopia

To describe a pattern of combined exotropia and hypotropia in patients with unilateral high myopia and to suggest a surgical approach for their management. In this observational study of 13 patients presenting with unilateral combined exotropia and hypotropia with high axial myopia in the deviating amblyopic eye, cycloplegic refraction, visual acuity, ocular motility, and orbital imaging findings were evaluated. For patients who had undergone surgery, the intraoperative findings and their surgical outcome were also analyzed. Median age at presentation was 27±14.6years. In the deviated eyes, mean spherical equivalent was -13.6±9 D; mean axial length, 28.3±1.7mm. The mean preoperative horizontal and vertical angles of deviation in primary gaze were 46.5±12.1Δ (range, 25-60) and 21.1±6.5Δ (range, 15-35), respectively. All patients had a V pattern, with limitation of elevation in abduction. Magnetic resonance imaging revealed no evident displacement of the lateral rectus muscles in all cases. Six patients (46%) had surgical intervention. In 5 cases, the lateral rectus was displaced inferiorly by a mean of 2.5mm (range, 2-4mm) and was recessed and transposed 8mm upward. The muscle was then fixated to the sclera with a nonabsorbable polyester suture 2-4mm behind its new insertion. Successful surgical outcome was achieved in 5 cases (83%). Combined exotropia and hypotropia associated with high myopia shows an overlap in the clinical presentation of the heavy eye syndrome. Although not evident radiologically, downward displacement of lateral rectus muscle was documented intraoperatively.

2924 Oophoropexy in Adolescent Patients

Video Objective This video demonstrates a technique of oophoropexy through plication of the utero-ovarian ligament to the round ligament. Setting The patient is a 13 year old P0 with a history of right ovarian torsion 10 months prior, for which she underwent laparoscopic detorsion without oophoropexy. She re-presented to the ED with two weeks of severe intermittent right lower abdominal pain, associated with nausea and vomiting. MRI abdomen/pelvis revealed twisting of the right ovarian pedicle. In addition, the right ovary was enlarged due to ovarian stromal edema, and there was peripheralization of the follicles. There was no ovarian cyst or mass. At the time of evaluation, the patient was not experiencing pain and she was clinically stable. She was suspected to have intermittent torsion. The patient and her parents were counseled on the option of observation and outpatient follow up versus surgical management with oophoropexy. They desired to proceed with surgical management. Interventions Oophoropexy was performed with a horizontal mattress of non-absorbable Polyester suture from the round ligament, through the mesosalpinx, and to the utero-ovarian ligament. Conclusion Evidence supports ovarian oophoropexy rather than oophorectomy for recurrent ovarian torsion in adolescents. Despite this the National Inpatient Sample (NIS) estimates 78% of adolescents underwent oophorectomy. We demonstrate a method of oophoropexy for recurrent ovarian torsion. The case patient has remained asymptomatic since her procedure. In conclusion, oophoropexy should be considered for adolescent patients with recurrent ovarian torsion to decrease risk of recurrence and to preserve fertility.

Reattachment of an osteotomized greater trochanter in total hip arthroplasty using an ultra-high molecular weight polyethylene fiber cable

BackgroundThe optimum approach in total hip arthroplasty (THA) should reduce the risk of postoperative dislocation or limping, be applicable in every case, and be reusable in the future. The purpose of this study was to introduce our transgluteal approach for THA and to evaluate the type and frequency of complications around the greater trochanter. MethodsThis study retrospectively evaluated 892 THA cases between January 2010 and March 2015 performed using our transgluteal approach that osteotomized only the lateral anteroinferior greater trochanter. The trochanteric fragment was reattached using one of three different protocols: Group A, three non-absorbable polyester sutures; Group B, two non-absorbable polyester sutures and one ultra-high molecular weight polyethylene (UHMWPE) fiber cable; or Group C, two UHMWPE fiber cables. Postoperative complications were assessed and recorded, and univariate logistic regression analyses were performed to determine whether risk factors and radiological complications around the greater trochanter were correlated. ResultsNone of the hips required revision for infection, dislocation, or limping. The rate of radiological complications around the greater trochanter at 1 year was 19.2% in Group A, 16.3% in Group B, and 7.9% in Group C (p < 0.001). Risk factors for radiological complications included the patient's disease or the surgeon's experience in Group A and the patient's age or the surgeon's experience in Group C. In the relationship between postoperative pain around the greater trochanter and radiological complications, there were no significant differences in all groups; no group interaction was observed (p= 0.3875). ConclusionThe UHMWPE fiber cable was effective to reduce complications of the reattached osteotomized greater trochanter in THA.

537 Dorsal phalloplasty: Revealing the concealed penis along with penile prosthesis implantation

72% of patients complain of shortening following penile prosthesis implantation (PPI). Dorsal phalloplasty (DP) is a minimally invasive same-session adjuvant to PPI, where a tacking suture approximates the under surface of the peno-pubic junction (PPJ) to the pubis , enhancing length. This work describes long term follow up results of DP This is a controlled prospective study of 66 patients who underwent simultaneous PPI and DP (PPIDP group), and 60 underwent PPI without DP (Control group). For the PPID group, the tacking suture was placed using size-5 non-absorbable Polyester suture material, passed through the pubic periosteum then into the subcutaneous tissue and dermis of the PPJ, and left untied, followed by implantation, then tying the tacking suture. DP was evaluated as per measured gain in erect length in the PPIDP group indicated by the difference between pre-tacking and post-tacking length, maintenance of that length gain until final follow up, as well as by the difference between both groups in impression on post-implantation length compared to length before ED had set in (“longer”, “same” or “shorter”), and satisfaction with length on a five-point Lickert scale).

Could the novel 'double-hole' technique be an alternative for the inflow occlusion method?

SummaryBackgroundInflow occlusion on beating heart and cardiopulmonary bypass techniques have been proposed for the removal of foreign material, such as stents, catheters and mass lesions, from cardiac chambers. However, both techniques are not devoid of disadvantages and complications. In this article, we define an alternative, novel ‘double-hole’ technique, which is based on opening the right atrium without cardiopulmonary bypass .MethodsBovine hearts were obtained from a local supermarket. Two purse-string sutures were placed in the right atrium using 2-0 braided, non-absorbable polyester suture material, one close to the auricle, and the other close to the interatrial septum. The guidewire of a haemodialysis catheter was inserted through the superior vena cava into the right atrium and passed all the way through the right ventricle.ResultsWe suggest that the double-hole technique may be useful, especially in revision cases with adhesions. Further research should be performed to document the efficacy and safety of this method.ConclusionWe are aware that further extensive research is necessary to investigate the utility of this novel technique in contemporary cardiovascular surgery. We believe the doublehole technique has the potential to become a safe, practical and effective measure in the future.

Postoperative shift in ocular alignment following single vertical rectus recession on adjustable suture inadults without thyroid eye disease.

To determine whether overcorrection shifts occur after vertical rectus recession on adjustable suture in the absence of thyroid eye disease. The medical records of patients without thyroid eye disease who underwent vertical rectus recession surgery from 2001 to 2008 were retrospectively reviewed for shifts in alignment between suture adjustment at postoperative day 1 and 2 months' follow-up. Superior rectus and inferior rectus recessions were compared. In addition, we compared the use of a nonabsorbable polyester suture to an absorbable polyglactin 910 suture in nonthyroid patients undergoing inferior rectus recessions. A total of 59 patients were included (superior rectus, 30; inferior rectus, 29). We found a mean undercorrection shift of 1.1 (range, 17.5(Δ) undercorrection to 16(Δ) overcorrection) and 1.0(Δ) (range, 12(Δ) undercorrection shift to 6(Δ) overcorrection shift) for superior and inferior rectus recessions, respectively, between 1 day and 2 months postoperatively. There was no trend toward overcorrection following unilateral vertical rectus adjustable suture recessions in patients without thyroid eye disease, suggesting that thyroid myopathy may account for overcorrection shifts seen with this surgery.

Device Interventions for Stroke Prevention in Atrial Fibrillation

Atrial fibrillation (AF) is the most common sustained heart rhythm disorder, with an estimated prevalence of 0.4% to 1% in the general population. In addition, AF is responsible for approximately 15% to 20% of ischemic strokes. Device interventions to prevent strokes in patients with AF are nonsurgical procedures to block blood clots (thrombus) from forming and traveling out of the heart. The “quivering” rather than normal contractions of the upper chambers of the heart (atria) from disorganized electric activity (AF) leads to blood stasis and thrombus formation. A small cul-de-sac called the left atrial appendage (LAA) is especially prone to thrombus formation (Figure 1). In AF patients without valvular heart disease, almost all thrombus originates from the LAA. The thrombus travels to and block major vessels in the body. Blocking blood vessels to the brain leads to strokes and transient ischemic attacks (mini-strokes). Figure 1. Transesophageal echocardiogram image of a thrombus in the left atrial appendage (dotted line). Patients with the following risk factors have a higher stroke risk: heart failure, hypertension, age of 75 years or greater, diabetes mellitus, and prior history of strokes or mini-strokes. These are often combined to form the CHADS2 score. The more risk factors you have, the higher your CHADS2 score and risk of stroke are. Blood-thinning medications (anticoagulants) such as warfarin, dabigatran, rivaroxaban, and apixaban are effective stroke prevention therapies. The risks of bleeding associated with long-term anticoagulation led to the development of permanent treatment options like surgery. Closures by sutures (ligation) and removal (amputation) of the LAA …

Kyste synovial induit par des sutures méniscales non résorbables

Arthroscopic meniscal repair has been a common procedure for the treatment of a torn meniscus, since the importance of meniscal preservation is widely understood. Over the years, the complications associated with suture material have been reported. Meniscal cyst is also one of those things. But ganglion cyst triggered by non-absorbable suture material was not documented in the literature. We report the case of a 19-year-old boy who underwent arthroscopic ACL reconstruction and repair of the medial meniscus by inside-out technique using 2-0 non-absorbable polyester sutures. The patient returned to our clinic at 4 year F/U with right knee pain due to medial meniscus tear and ganglion cyst. We suspect non-absorbable suture materials itself might have caused soft tissue irritation with repetitive trauma that lead to mucoid degeneration which results in ganglion cyst formation in the end.

Adjustable Superior Oblique Tendon Spacer with Application of Nonabsorbable Suture for Treatment of Isolated Inferior Oblique Paresis

To evaluate and report the outcomes of a superior oblique tendon spacer procedure using nonabsorbable adjustable sutures in patients with inferior oblique (10) paresis. This interventional case series included 6 eyes of 6 patients with 10 paresis. All met Bielschowsky/Parks Three-step Test criteria to identify an isolated 10 paresis. In all patients, the superior oblique tendon was exposed; 2 nonabsorbable polyester sutures were placed 3 mm apart, and the tendon was cut. With the use of a slipknot, the cut ends of the tendon were separated 5 to 7 mm. Tendon separation was adjusted intraoperatively according to the fundus torsion and exaggerated traction test. The mean duration of follow-up was 8.1 months (range, 5-12 [corrected] months). Four patients had congenital 10 paresis and 2 had iatrogenic 10 paresis following denervation/myectomy of 10. Mean primary position hypotropia improved from 15.2 prism diopters (PD) before surgery to 2.7 PD in congenital 10 paresis and from 11.5 PD to 2.5 PD in iatrogenic 10 paresis. In congenital 10 paresis, mean preoperative superior oblique overaction and 10 underaction was +2 and -2, which decreased to 0 and -1.25 respectively; fundus incyclotorsion resolved in all patients. Superior oblique overaction and 10 underaction improved in iatrogenic 10 paresis as well. In no patient did an overcorrection develop. The adjustable superior oblique tendon suture spacer procedure is an effective and safe option for correcting 10 paresis without developing iatrogenic superior oblique paresis.

Biomechanical characteristics of single-row repair in comparison to double-row repair with consideration of the suture configuration and suture material

The aim of the study was to evaluate the time zero mechanical properties of single- versus double-row configuration for rotator cuff repair in an animal model with consideration of the stitch technique and suture material. Thirty-two fresh-frozen sheep shoulders were randomly assigned to four repair groups: suture anchor single-row repair coupled with (1) braided, nonabsorbable polyester suture sized USP No. 2 (SRAE) or (2) braided polyblend polyethylene suture sized No. 2 (SRAH). The double-row repair was coupled with (3) USP No. 2 (DRAE) or (4) braided polyblend polyethylene suture No. 2 (DRAH). Arthroscopic Mason–Allen stitches were used (single-row) and combined with medial horizontal mattress stitches (double-row). Shoulders were cyclically loaded from 10 to 180 N. Displacement to gap formation of 5- and 10-mm at the repair site, cycles to failure, and the mode of failure were determined. The ultimate tensile strength was verified in specimens that resisted to 3,000 cycles. DRAE and DRAH had a lower frequency of 5- (P = 0.135) and 10-mm gap formation (P = 0.135). All DRAE and DRAH resisted 3,000 cycles while only three SRAE and one SRAH resisted 3,000 cycles (P < 0.001). The ultimate tensile strength in double-row specimens was significantly higher than in others (P < 0.001). There was no significant variation in using different suture material (P > 0.05). Double-row suture anchor repair with arthroscopic Mason–Allen/medial mattress stitches provides initial strength superior to single-row repair with arthroscopic Mason–Allen stitches under isometric cyclic loading as well as under ultimate loading conditions. Our results support the concept of double-row fixation with arthroscopic Mason–Allen/medial mattress stitches in rotator cuff tears with improvement of initial fixation strength and ultimate tensile load. Use of new polyblend polyethylene suture material seems not to increase the initial biomechanical aspects of the repair construct.

Superior oblique tendon spacer with application of nonabsorbable adjustable suture for treatment of Brown syndrome

To evaluate the outcomes of a superior oblique tendon spacer procedure using nonabsorbable adjustable sutures in patients with Brown syndrome. This noncomparative interventional case series includes 25 eyes of 25 patients with Brown syndrome. In all patients the superior oblique tendon was exposed; two nonabsorbable polyester sutures were placed 4 mm apart, and the tendon was cut. With the use of a slipknot, the cut ends of the tendon were separated 5 to 8 mm. Tendon separation was adjusted intraoperatively according to the exaggerated traction test and indirect ophthalmoscopy. Overall 25 eyes of 25 patients with mean age of 8.00 +/- 4.62 years were operated and followed for a mean period of 13.2 +/- 7.6 months (range, 3 to 30 months). Mean elevation in adduction improved from -3.96 before surgery to -0.67 (p < 0.001); mean hypotropia improved from 11.08(Delta) to 0.32(Delta) (p < 0.001). Two patients developed overcorrection, but recurrence was not observed in any case. The patients continued to improve over the follow-up period. The adjustable superior oblique tendon suture spacer procedure has favorable results and seems to be technically easier than a silicone expander procedure for Brown syndrome.

Periosteal Fixation in Third-Nerve Palsy

We present a new technique of anchoring the eyeball to the nasal periosteum using a nonabsorbable suture in acquired isolated third-nerve paresis. This was a case series of 4 consecutive adult subjects with isolated third-nerve paresis. After a 12-mm lateral rectus muscle recession in all 4 subjects, we passed 5-O double-armed polyester (NW683 Ethibond; Ethicon, Division of Johnson and Johnson Ltd., Aurangabad, India) on spatulated needles through the periosteum overlying the anterior lacrimal crest (exposed as in a Dacryocystorhinostomy procedure) at its superior part. The needles were brought anterior to the medial rectus muscle insertion and tightened enough to align the eye in 8-10 prism diopters adducted position. Ocular alignment in the primary gaze was satisfactory at 6-12 months of follow up. The use of a nonabsorbable polyester suture to anchor the globe to the nasal periosteum is an additional technique that holds promise to align the eyes in the primary gaze.

Failure mode of suture anchors as a function of insertion depth in human cadaver humeri (SS-48)

Rotator cuff integrity after repair is a major determinant of a good functional result and residual deficiencies have been found in greater than 50% of complex tears. Different modes of suture anchor failure have been identified and may occur due to anchor displacement or pullout, suture breakage, knot slippage, or suture pulling though the tendon. Recently, another mode of anchor failure has been identified in the bovine model by suture cutting though the bone when an anchor is placed deeper than recommended. However, this result has not been reproduced using human cadaveric shoulders. The purpose of this study was to evaluate the biomechanical stability of a suture anchor placed deep within the rotator cuff footprint of human cadaver humeri. Methods: Metallic screw-in anchors loaded with a single, number 2 braided nonabsorbable polyester suture were placed in the infraspinatus footprint of eight human cadaver humeri (87 ± 3 years) at two depths. Standard placement had the threads countersunk 3 mm below the bone surface. The deep anchors doubled this depth to 6 mm. The sutures were placed under 10 N of preload and the knots were placed equidistant from the bone hole exit and a smooth metallic rod used for mechanical testing. Specimens were cyclically loaded between 10 to 45 N to a maximum of 500 cycles and then, if still intact, loaded at 0.5 mm/sec to failure. Total displacement after cyclic testing (mm) and ultimate failure load (N) were analyzed with a one-way ANOVA (P < .05). Failure mode and location were recorded after testing. Results: The total displacement after cyclic loading was significantly different between repair depths. The deep anchors attained a total displacement of 8.4 ± 2.4 mm while the standard anchors had a final displacement of 5.7 ± 1.4 mm (P < .03). There was no difference in ultimate failure load between depths, with the deep anchors failing at 144 ± 14 N and standard anchors failing at 143 ± 13 N. The deep anchors were noted to translate to the cortical margin within the first few cycles. Both anchor positions seemed to rotate at the cortical surface due to the orientation of loading as testing progressed. Failure occurred at the eyelet in two tests, while the remaining tests exhibited anchor translation/rotation and some suture cut through. Discussion: Burying suture anchors beyond the specified insertion depth is inadvisable based on these data. Excessive anchor depth may lead to early clinical failure by the suture cutting through bone. Both anchor depths displayed rotation and translation at the cortical surface and some migrated above the joint surface during physiologic cyclic loading. The rotation and translation may induce early deficiencies in the cuff repair while the migration may limit joint range of motion and induce joint arthrosis. Due to poor bone quality, these rotations/translations are of specific concern in the osteoporotic population. Improved anchor eyelet designs may lessen the possibility of abrasive degradation of the suture, and abrasion-resistant materials may decrease the risk of suture fretting.
