Purpose: Point fixation at the margin of the glenoid is a limitation of conventional arthroscopic stabilization using suture anchors, and does not afford sufficient footprint healing, especially in glenoid bone deficiency. So, we introduce an arthroscopic suture bridge transosseous-equivalent technique for bony Bankart lesions to avoid the technical disadvantage of point contact with anchor fixation and to improve mechanical stability through cross compression of the labrum. Surgical approach: The technique was adapted from the transosseous-equivalent rotator cuff repair technique using suture bridges, which improved the pressurized contact area and mean pressure between the tendon and footprint. After preparation of the glenoid bed by removal, reshaping, or mobilization of the bony lesion, two anchors (3.0 mm Biofastak, $Arthrex^{(R)}$, Naples, FL) were inserted into the superior and inferior portion of the bony Bankart lesion. Using a suture hook, medial mattress sutures were applied around the capsulolabral portion of the IGHL complex to obtain sufficient depth of glenoid coverage. A 3.5 mm pushloc anchor ($Arthrex^{(R)}$, Naples, FL) hole was made in the articular edge of the anterior glenoid rim. distal, suture bridge was applied, and proximal was inserted to mobilize the labrum in the proximal direction. This avoided the technical disadvantage of point contact with anchor fixation and decreased the level of gap formation through cross-compression of the labrum.

Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

An anterior cruciate ligament (ACL) avulsion fracture is an uncommon injury that occurs predominantly in the pediatric and adolescent population. Accurate reduction and fixation of an avulsed fragment are necessary to restore and maintain the length of the ACL and normal knee biomechanics. Several techniques are available to repair an ACL avulsion fracture. On the other hand, treatment is controversial in skeletally immature patients due to risk of physeal injury. This paper reports a case of an ACL avulsed fracture in a skeletally immature patient treated with arthroscopic all-inside suture bridge repair, in which an excellent result and firm stability were obtained without physeal injury.

Purpose: To examine the clinical and structural outcomes of an at least two-year follow-up of arthroscopic full-thickness rotator cuff repairs with a single-row or suture-bridge technique in patients more than 65 years of age. Materials and Methods: Patients diagnosed with a full-thickness rotator cuff tear who were more than 65 years of age, underwent arthroscopic rotator cuff repair after at least six months of conservative treatment, agreed to take a follow-up magnetic resonance imaging (MRI) six months postoperatively, and visited outpatient for at least two years were enrolled in this study. Clinical evaluations were done using The University of California Los Angeles score, Constant Shoulder Score, and visual analogue scale evaluated two years after the surgery. The structural integrity was analyzed using follow-up MRI. During surgery, a suture-bridge technique was used if the rotator cuff tendon could cover half of the footprint under constant tension. Otherwise, single-row repair was performed. Results: The samples were 158 cases, consisting of 93 single-repairs and 65 suture-bridge repairs. A preoperative comparison of the age distribution, fatty degeneration of supraspinatus and infraspinatus muscle, medial retraction of torn cuff tendon, and tear size between the two groups were not significant. The clinical scores were improved significantly in all cases. The distribution of the structural integrity by Sugaya classification were 49 cases in type 1 (31.0%), 62 cases in type 2 (39.2%), 30 cases in type 3 (19.0%), 11 cases in type 4 (7.0%), and six cases in type 5 (3.8%). The re-tear rate of the single-row group was 9.7% (nine out of 93 cases) and 12.3% (eight out of 65 cases) for the suture-bridge group. Conclusion: Satisfactory clinical and radiological outcomes were achieved after arthroscopic full-thickness rotator cuff repair in patients more than 65 years of age. Both single-row and suture-bridge techniques would be beneficial for the elderly.

Purpose: To determine clinical results for arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique. Materials and Methods: Between November, 2007 and October, 2008, we evaluated 90 cases of arthroscopic middle, large rotator tear cuff repair. The mean follow-up period was 15 months (range, 12-23 months). Forty-three cases had medium-sized tears; 47 cases had large-sized tears. At the preoperative stage and again at last follow-up, functional results were assessed by the KSS, ASES, UCLA and the PVAS (Pain visual analogue score). Results: Pain score improved from 2.56 preoperatively to 0.96 at final follow-up; movement scores improved from 6.94 to 1.70. At. final follow-up, the average UCLA score improved from 17.08 to 31.17 with 31 excellent (34%), 49 good (54%) and 10 poor results (12%). The final UCLA score was 31.47 in the group less than 60 years of age and 30.69 in the group over 61 years of age (p=0.344). The UCLA score was 31.23 in those with medium-sized tears and 31.11 in those with large-sized tears (p=0.924). The UCLA score was 31.10 in non-trauma patients and 31.23 in trauma patients (p=0.929). Conclusion: Arthroscopic repair of a full-thickness rotator cuff tear using a suture bridge technique can produce excellent clinical results. These outcomes are not affected by age or trauma history.

Background: The transosseous anchorless repair (ToR) technique was recently introduced to avoid suture anchor-related problems. While favorable outcomes of the ToR technique have been reported, no previous studies on peri-implant cyst formation with the ToR technique exist. Therefore, this study compared the clinical outcomes and prevalence of peri-implant cyst formation between the ToR technique and the conventional transosseous equivalent technique using suture anchors (SA). Methods: Cases with arthroscopic rotator cuff repair (ARCR) between 2016 and 2018 treated with the double-row suture bridge technique were retrospectively reviewed. Patients were divided into ToR and SA groups. To compare clinical outcomes, 19 ToR and 57 SA cases without intraoperative implant failure were selected using propensity score matching (PSM). While intraoperative implant failure rate was analyzed before PSM, retear rate, peri-implant cyst formation rate, and functional outcomes were compared after PSM. Results: The intraoperative implant failure rate (ToR, 8% vs. SA, 15.3%) and retear rate (ToR, 5.3% vs. SA, 19.3%) did not differ between the two groups (all P>0.05). However, peri-implant cysts were not observed in the ToR group, while they were observed in 16.7% of the SA group (P=0.008). Postoperative functional outcomes were not significantly different between the two groups (all P>0.05). Conclusions: The ToR technique produced comparable clinical outcomes to conventional techniques. Considering the prospect of potential additional surgeries, the absence of peri-implant cyst formation might be an advantage of ToR. Furthermore, ToR might reduce the medical costs related to suture anchors and, thereby, could be a useful option for ARCR. Level of evidence: III.

Purpose: The purpose of this study was to evaluate the repair integrity and clinical outcomes of delaminated tears following arthroscopic layered suture bridge rotator cuff repair in a prospective fashion. Materials and Methods: A consecutive series of 67 patients with delaminated rotator cuff tears who underwent surgery using the arthroscopic Layered Suture Bridge Technique were followed prospectively. Of 67 shoulders, 26 patients were male and 40 patients were female (one patient had bilateral tears); the mean age was 58.8(40~76) years. The clinical evaluation was performed according to ASES, UCLA, and KSS (Korea Shoulder Scoring System) scores with an average follow up period of 33 months. Repair integrity was estimated using MRI, which was performed six months postoperatively. Results: The average clinical outcome in ASES, UCLA, and KSS scores showed significant improvement at the time of the final follow-up compared to preoperatively, from 50.2 to 92.3, 15 to 31.3, and 54.4 to 90.7, respectively (p<0.001 for all scores). Follow up by MRI showed that 16 shoulders had a type-I; 14, a type-II; five, a type-III; two, a type-IV; one, a type-V re-tear. The overall rate of re-tear (types IV and V) was 7.9%. Conclusion: Use of the Arthroscopic Layered Suture Bridge Technique can result in improved functional and structural outcome in cases of delaminated rotator cuff tear.
