Functional and Symptomatic Improvements Based on the Femoral Tunnel Drilling Technique in Anterior Cruciate Ligament (ACL) Reconstruction.

The current literature comparing femoral tunnel techniques often reports on short-term outcomes after anterior cruciate ligament reconstruction (ACLR), but only a few studies have analyzed long-term outcomes. In addition, many studies have compared transtibial to anteromedial portal techniques without differentiating whether rigid or flexible reaming is used, making it difficult to infer how the techniques truly compare to one another. This study aimed to detect differences in patient-reported outcome scores in those treated with three different femoral tunnel drilling techniques. This study is a prospective cohort study. Of 650 patients treated for anterior cruciate ligament (ACL) injuries with ACLR, 350 were 5+ years out from surgery. Of these patients, 111 completed patient-reported outcome surveys (PROs). The Kruskal-Wallis H test was used to detect differences between patients treated with either of the three femoral tunnel drilling techniques: transtibial (TT), anteromedial portal with rigid reaming (AMP-RR), or anteromedial portal with flexible reaming (AMP-FR). Bonferroni correction was applied to the p-values to reduce the risk of making a type 1 error. No differences were found between the three groups in demographics or postoperative PROs. However, there was a significant change between pre-surgery and post-surgery PROs. TT, when compared to AMP-RR, had a greater increase in satisfaction and greater improvement in a patient's ability to go up and down the stairs from pre-surgery to post-surgery. AMP-FR, when compared to TT, had greater improvement of the patient's knee stiffness/swelling. AMP-FR, when compared to AMP-RR, had greater improvement in knee pain during stairs and the ability to go down the stairs. No differences in return to sport, additional procedures on the affected knee (meniscal surgeries or cyclops lesion excisions), or revision surgery rates were found. Overall, postoperative PROs did not show statistically significant differences between the three femoral tunnel drilling techniques. Differences, however, were identified in the responses to specific questions on PRO surveys, which may have otherwise been overlooked. It is important to recognize the differences between TT, AMP-RR, and AMP-FR in the improvement of stair climbing and swelling/stiffness as these likely directly affect a patient's satisfaction from pre-ACLR to post-ACLR.

Effectiveness of Tunnelling Modification Technique Using Platelet-rich Fibrin and Connective Tissue Graft in Gingival Recession: A Systematic Review

Background Gingival recession is a concern in aesthetic and functional perspective. The tunneling technique (TT) is one of the effective root coverage treatments in some gingival recession defects and is associated with favorable outcomes. This paper aims to evaluate the effectiveness of platelet-rich fibrin (PRF) and connective tissue graft (CTG) in gingival recession treatment with TT. Methods This systematic review used the PRISMA method and electronic bibliographic searches were conducted on seven databases (Google Scholar, Wiley, Pubmed, Sage, Ovid Technologies, Quintessence Publishing, Springer) from December 2018 to January 2023. The search focused on randomized clinical trials (RCTs) that reported TT outcomes in the treatment of Miller class I and II recession with a minimum of six months follow-up. Results Three out of 399 studies met the inclusion criteria. The three selected studies presented PRF and CTG use in multiple gingival recessions to evaluate tissue condition and clinical parameters before and after the surgical procedure. The clinical parameters evaluated were probing pocket depth (PPD), recession width (RW), width of keratinized gingiva (WKG), and vertical depth of recession (VDR). TT with PRF and TT with CTG is effective in treating gingival recession. PRF is well accepted by patients with a less invasive procedure compared to the CTG procedure. However, TT with CTG showed better results in all parameters at follow-up. Conclusions TT with PRF can be used as an alternative to treat some gingival recession defects. However, TT with CTG produced better clinical results in recession closure.

A novel surgical technique to resolve mucosal fenestration of a root apex: Apical tunnel surgery: A case report.

Endodontic surgery, which includes apex resection, retro-fill and some regeneration procedures, is a traditional way to deal with apex fenestration. The endodontic surgery could bring large flap, curtate root length, non-healing mucosa and soft tissue deficiency in the apex area. Other treatment options might be considered according to different etiological factors. Mucogingival surgery provides some ideas in accumulation of soft and hard tissues, especially some unique methods such as "tunnel technique" bringing us a view of minimal invasive surgery approach. A novel surgery named "apical tunnel surgery" was reported here to resolve a root apex exposure with the tunnel-like technique. A young female complained about root exposure of upper right anterior tooth without history of trauma or orthodontic treatment. The intraoral examination revealed a buccal root apex exposure about 3mm in diameter of #12 (FDI teeth numbering system). The tooth was slightly dark with Class 1 mobility. The periodontal situation was good and the occlusion check revealed no traumatic bite on #12. The cone-beam computed tomography (CBCT) showed a bone fenestration from the buccally lower 1/2 root surface to the apex and bone absorption around the apex. It also revealed a bone contour deficiency in #12 area. Root canal treatment, root surface debridement, and soft tissue combined with hard tissue accumulation were carried out in one tunnel-like surgery. Examination of 12-month follow-up showed a healed and thickened mucosa in the buccally apical region and CBCT showed the continuous lamina dura occupied the buccal aspect of #12 root apex. This new apical tunnel surgery provided soft and hard tissue accumulation in one minimal invasive way in the apex exposure case caused by bone fenestration and thin mucosa.

Staged Regenerative-Phenotype Modification Therapy for Multiple RT3 Gingival Recessions in Periodontally Compromised Anterior Mandibular Teeth: A Case Report.

We report the successful treatment of multiple recession type (RT) 3 gingival recessions in periodontally compromised mandibular anterior teeth with limited keratinized tissue. A 35-yearold man with stage III, grade C periodontitis underwent a two-stage intervention. Initially, a modification of the connective tissue graft (m-CTG) wall technique was used as part of phenotype modification therapy. The CTG acted as a protective 'wall,' securing space for periodontal regeneration, enhancing root coverage, soft tissue thickness, and keratinized mucosal width. Recombinant human fibroblast growth factor-2 and carbonate apatite promoted periodontal regeneration. This procedure successfully facilitated periodontal regeneration, resulting in the transition from RT3 to RT2 gingival recession and adequate keratinized mucosal width. Eighteen months later, the second surgery used a tunneled coronally advanced flap (TCAF) for root coverage. TCAF involved combining a coronally advanced flap and tunnel technique by elevating the trapezoidal surgical papilla and using a de-epithelialized CTG inserted beneath the tunneled flap. Root conditioning with ethylenediaminetetraacetic acid and enamel matrix derivative gel application were performed. Consequently, mean CAL gain was 5.3 mm, mean root coverage was 4.5 mm in height, and the gingival phenotype improved at the treated sites by the 12-month follow-up. This staged approach addresses the challenges of treating RT3 gingival recession with promising outcomes.

Endoscopic repair of nasal septal perforation with anterior ethmoidal artery flap using tunnel technique.

Septal perforations (SPs) present a distinct challenge. There are many described surgical approaches with variable success rates. The goal of this study is to describe a new technique in repairing SP. A case series of eighteen patients with anterior septal perforation who underwent endoscopic repair with the "tunnel technique" based on anterior ethmoid artery flap (AEA) were analyzed. Demographic data, etiology, size of perforation, and success rate were collected. Eighteen cases with male predominance (67%) were enrolled from 2019 to 2022. The average perforation size was 1.5 cm (0.5- 3.6 cm). The success rate of complete SP closure was 94% (n = 17/18) with no complications after surgery. The patients were followed up for 7 ± 5.2 months. AEA flap reconstruction with the tunnel technique is associated with favorable outcomes in SP closure. The tunnel technique provides a useful flap bolster and minimizes the use of other supportive measures. This technique offers an addition to other techniques for septal perforation repair. Level 4.

Effect of Coenzyme Q10 on early wound healing after recession coverage surgery with the modified coronally advanced tunnel technique and a connective tissue graft: A 6-month, triple-blinded, randomized, placebo-controlled pilot trial

ObjectivesCoenzyme Q10 (CoQ10) or ubiquinone is one of a cell’s most important electron carriers during oxidative phosphorylation and many other cellular processes. As a strong anti-oxidant with further anti-inflammatory effects CoQ10 is of potential therapeutical value. The aim of this randomized controlled clinical trial was to investigate the effect of topical CoQ10 on early wound healing after recession coverage surgery using the modified coronally advanced tunnel (MCAT) and palatal connective tissue graft (CTG).Materials and methodsThirty patients with buccal gingival recessions were evaluated after being randomly allocated to: 1) MCAT and CTG with topical application of a coenzyme Q10 spray for 21 days or 2) MCAT and CTG with placebo spray. Wound healing was evaluated by the early wound healing index (EHI). Patient-reported pain was analyzed by a 100-mm visual analogue scale (VAS) at day 2, 7, 14 and 21 post-surgically. Mean recession coverage, gain of keratinized tissue and esthetic outcomes were assessed at 6 months.ResultsEHI and pain scores showed no significant differences. Time to recovery defined as VAS<10 mm was shorter in the test group. Mean root coverage after 6 months was 84.62 ± 26.57% and 72.19 ± 26.30% for test and placebo, p=0.052. Complete root coverage was obtained in 9 (60%) test and in 2 (13.3%) placebo patients. Increase in keratinized tissue width and esthetical outcomes were similar for both groups.ConclusionCoQ10 had no significant effect on early wound healing and on mean root coverage after 6 months.Clinical relevanceEarly wound healing: in young healthy patients with no inflammatory oral conditions topical CoQ10 does not improve early healing.

Management of gingival recession with modified coronally advanced tunnel technique: Case report

Management of gingival recession with modified coronally advanced tunnel technique: Case report

The modified Nice knot has improved mechanical performance compared to the cinch stitch for meniscal root repair.

According to previous biomechanical studies, the success of meniscus root repair depends on the suture-meniscus interface and optimisation of this procedure seems to be critical. A progressive, reliable and adjustable knot has numerous advantages in meniscal repair since the surgeon can adapt and meticulously tune the final strength of the fixation. We hypothesised that a single passage of one tape at two different points of the posterior meniscal root with a modified Nice knot configuration may allow similar or superior fixation for root repair compared to the cinch stitch suture technique. Posterior root repair of medial and lateral meniscus was performed on 26 porcine knees. In group (A), two simple cinch stitches were applied, and in group (B), a modified Nice knot was used in a crossmatch configuration. For both groups, two passages through the meniscus with a 2-mm braided tape were used, and a single transosseous tibial tunnel technique was performed and tested in pull-out conditions. The modified Nice knot showed an improved biomechanical performance considering the maximum failure load for both the medial (600.7 ± 77.5 N) and lateral (686.1 ± 83.5 N) (p = 0.006) posterior root fixation when compared to a double cinch stitch (558.0 ± 123.9 N) and (629.0 ± 110.2 N) (p = 0.178) for medial and lateral fixation, respectively. The maximum stiffness was also higher for the modified Nice knot configuration for both medial (17.1 ± 1.5 vs. 13.3 ± 1.6 N/mm) and lateral meniscus (20.0 ± 2.6 vs. 13.8 ± 2.3 N/mm), being this difference statistically significative (p = 0.001). The modified Nice knot allowed better adaptation in the pull-out tests and presented higher fixation strength, stiffness and reproducibility, with lower standard deviation, being at the same time economically advantageous, since only one tape is needed. Level III.

Meniscus Allograft Transplantation in Conjunction With Arthroscopic Biologic Knee Restoration Delays Arthroplasty in Patients Older Than 50 Years

The purpose of this study is to evaluate the utility of meniscus allografts in combination with other procedures to delay knee arthroplasty in patients older than 50 years of age previously advised joint arthroplasty. One hundred eight meniscus allograft transplants (MATs) using the arthroscopic three tunnel technique between 1997 and 2019 in patients over 50 years of age were retrospectively reviewed with two-year minimum follow-up period. Inclusion criteria were patients recommended knee arthroplasty with pain and preservation of some joint space by standing flexion x-rays. Exclusion criteria were lack of joint space, failure to comply with rehabilitation protocol or complete research questionnaires. International Knee Documentation Committee (IKDC) composite and isolated pain scale were evaluated longitudinally. Time from MAT to arthroplasty was measured with failure defined as allograft excision or revision, progression to arthroplasty, or same or increased pain. Eighty-six of 108 (79.6%) patients met eligibility criteria. Over the follow-up mean 8.55 (range of 0.68 to 25.2) years, 42 of 87 (48.2%) grafts progressed to arthroplasty with mean time of 8.64 (median 8.05) years. Concomitant procedures did not have significant impact on survival; however, survival medians were higher among paste graft and chondroplasty and lower among osteotomy groups. At the time of reporting, 41 of 84 (48.8%) patients had intact meniscus transplants, demonstrating significant improvements (p<0.001) in pain and function as assessed by IKDC. These improvements were sustained ten years post-operatively, correlated to a mean of 65.8 years of age. At least 50% of patients achieved Minimal Clinically Important Difference (MCID) through 10 years post-operatively. Meniscus allografts in combination with other arthroscopic interventions delay knee arthroplasty and improve knee symptoms of pain and function in a population of knee arthroplasty candidates over 50 years of age. Influences of concomitant procedures cannot be defined.

Precision Basecalling of Single DNA Nucleotide from Overlapped Transmission Readouts with Machine Learning Aided Solid-State Nanogap.

DNA sequencing with the quantum tunneling technique heralds a paradigm shift in genetic analysis, promising rapid and accurate identification for diverging applications ranging from personalized medicine to security issues. However, the widespread distribution of molecular conductance, conduction orbital alignment for resonant transport, and decoding crisscrossing conductance signals of isomorphic nucleotides have been persistent experimental hurdles for swift and precise identification. Herein, we have reported a machine learning (ML)-driven quantum tunneling study with solid-state model nanogap to determine nucleotides at single-base resolution. The optimized ML basecaller has demonstrated a high predictive basecalling accuracy of all four nucleotides from seven distinct data pools, each containing complex transmission readouts of their different dynamic conformations. ML classification of quaternary, ternary, and binary nucleotide combinations is also performed with high precision, sensitivity, and F1 score. ML explainability unravels the evidence of how extracted normalized features within overlapped nucleotide signals contribute to classification improvement. Moreover, electronic fingerprints, conductance sensitivity, and current readout analysis of nucleotides have promised practical applicability with significant sensitivity and distinguishability. Through this ML approach, our study pushes the boundaries of quantum sequencing by highlighting the effectiveness of single nucleotide basecalling with promising implications for advancing genomics and molecular diagnostics.

Tunnel technique and subepithelial connective tissue graft, with or without cross-linked hyaluronic acid, in the treatment of multiple gingival recessions: 12-month outcomes of a randomized clinical trial.

This study evaluated the influence of the adjunctive application of a cross-linked hyaluronic acid (HA) in the treatment of multiple gingival recessions, using a modified coronally advanced tunnel (MCAT) technique and subepithelial connective tissue graft (SCTG) (MCAT+SCTG±HA). A randomized, split-mouth, double-masked comparison of the effects of MCAT+HA+SCTG (test) versus MCAT+SCTG (control) in the treatment of multiple, contralateral gingival recessions with clinical, esthetic, and histological evaluations was carried out. All samples were stained with hematoxylin and eosin, Masson's trichrome, Verhoeff-Van Gieson, and Alcian blue stain for semiquantitative evaluation. The primary outcome variable was 12-month mean root coverage (MRC). Twenty-four patients with 266 gingival recessions received both control and test treatments (133 recessions per group). 12-month MRC of the MCAT+HA+SCTG group was not significantly different from the MCAT+SCTG group with 84.32%±34.46% and 85.71%±36.43%, respectively (p=0.991). Both treatment modes produced favorable esthetic outcomes (root coverage esthetic score [RES] 9.51±1.01 tests vs. 9.26±1.10 controls, p=0.7292). However, the application of HA improved soft tissue texture (p=0.0091). The remaining end point measures did not differ significantly between groups. Histological evaluation showed a significantly greater number of elastic fibers and a moderate increase in collagen fiber density in biopsy samples taken from the test sides when compared to the control sides (p=0.0419 and p=0.300, respectively). MCAT+SCTG is an effective procedure in the treatment of multiple recession Type 1 (RT1) and RT2 recessions. There were no statistically significant differences in evaluated clinical treatment outcomes in the MCAT+HA+SCTG group compared to the MCAT+SCTG group within a period of 12 months. The application of HA increased collagen and elastic fiber density.

The influence of connective tissue grafting on the reconstruction of a missing facial bone wall using immediate implant placement and simultaneous bone reconstruction: a retrospective long-term cohort study

PurposeThis retrospective cohort study evaluates the influence of connective tissue grafts (CTG) on bone regeneration at implant sites with total loss of the buccal bone wall treated with flapless immediate implant placement (IIP) and reconstruction with autogenous bone chips (AB) within a follow-up of up to 13 years.MethodsSixty implants were inserted in 55 patients in sites with total loss of the buccal bone wall between 2008 and 2021. The implants were inserted and the buccal gaps were grafted by AB. A subgroup of 34 sites was grafted additionally with CTG using tunnel technique. Primary outcome was the vertical bone regeneration in height and thickness. Secondary outcome parameters were interproximal marginal bone level, recession, soft tissue esthetics (PES), width of keratinized mucosa (KMW) and probing depths (PPD).ResultsMean follow-up period was 60.8 months. In 55 sites a complete vertical bone regeneration was documented. The mean buccal bone level increased by 10.6 mm significantly. The thickness of the buccal bone wall ranged between 1.7 and 1.9 mm, and was significantly thicker in sites without CTG. Interproximal marginal bone level was at implant shoulder level. The mean recession improved significantly by 1.2 mm. In sites with CTG, recessions and PES improved significantly more.ConclusionsAdditional CTG in extraction sites with total buccal bone loss followed by IIP with simultaneous AB grafting led to improved PES and recession, but also to a thinner buccal bone wall compared to sites grafted just with AB.Graphical

Femoral to abdomen tunneling at the bedside for medium/long term venous access.

Femoral to abdomen tunneling of small-bore central venous catheters is a bedside technique for patients with contraindications to a thoracic approach, or as an alternative to a lower extremity catheter exit site. A femoral to abdomen tunneling technique was implemented for patients receiving medium and long-term intravenous treatments with contraindications to the thoracic venous approach or as an alternative to a lower extremity catheter exit site. All venous access devices were inserted with ultrasound guidance under local anesthesia, and catheter tip placement assessed by post procedural radiography. In this case series, from January 2020 to January 2023, a total of eight FTA-tunneled venous access devices were inserted. There were seven ambulatory patients and one bedbound patient. The median length of the subcutaneous tunnel was 20 cm, ranging from 15 to 27 cm. The median length of the intravenous catheter to the terminal tip was 31 cm, ranging from 23 to 40 cm. Tip location was confirmed by post-procedural abdominal radiograph. The catheter tip locations were interpreted to be at the level of T8-T9 (2), T12 (1), L4 (2), L2 (2), L1(1).No insertion or post insertion related complication was reported. Six patients completed the scheduled intravenous treatment. One patient was unable to be tracked due to transfer to an outside facility. One catheter initially demonstrated to be coiled over the left common iliac vessel was repositioned using a high flow flush technique. There was one reported catheter dislodgment by the nurse providing care and maintenance. The overall implant days were 961, with a median dwell time of 125 days ranging from 20 to 399 days. Femoral to abdomen tunneling provides an alternative exit site useful in select patients with complex intravenous access. The data of this small retrospective review suggests this a safe and minimally invasive bedside procedure.

Single Versus Double Tunnel Fixation in Medial Patellofemoral Ligament Reconstruction: A Meta-Analysis.

The purpose of this meta-analysis was to conduct a comparative analysis of clinical scores and complication rates among patients experiencing recurrent patellar dislocation who underwent medial patellofemoral ligament (MPFL) reconstruction using both single and double tunnel techniques. A comprehensive search was conducted across electronic databases including PubMed, the Cochrane Library, Web of Science, and Google Scholar to retrieve articles relevant to MPFL reconstruction utilising the tunnel technique. Subsequently, meta-analyses were undertaken to assess complication rates and changes in clinical scores before and after surgery. Following this, sensitivity analysis and meta-regression analysis were performed to scrutinise potential confounding variables. A total of thirty-two studies were included in the analysis, comprising twenty-seven non-comparative studies and five comparative studies. The findings revealed a similarity in postoperative complication rates between the single and double tunnel fixation techniques: [9.0% (95%CI, 4.0%-15.6%) versus 8.9% (95%CI, 4.7%-14.1%, p = 0.844)]. Likewise, no statistically significant differences were observed in Lysholm scores [34.1 (95%CI, 26.7-41.5) versus 33.8 (95%CI, 27.7-40.0, p = 0.956)], Kujala scores [29.4 (95%CI, 22.3-36.4) versus 27.3 (95%CI, 22.3-32.3, p = 0.637)], and Tegner score change [1.1 (95%CI, 0.8-1.4) versus 0.7 (95%CI, -0.2-1.6, p = 0.429)] before and after MPFL reconstruction, respectively, using these two techniques. In conclusion, the authors found that the clinical functional improvement and complication rates in MPFL reconstruction using the single tunnel fixation technique are comparable to those achieved with the double tunnel fixation approach. However, to further advance the understanding in this field, additional randomised controlled studies must be conducted to provide further insights. Key Words: MPFL reconstruction, Bone tunnel, Patellar dislocation, Meta-analysis.

Systematic application of SICA-PED protocol for central venous catheterization in neonates: A prospective clinical study on 104 cases.

Catheterization of central vessels can be associated with early and late, potentially fatal complications. A proactive approach is imperative to reduce the frequency and magnitude of adverse events. Recently, the GAVeCeLT has proposed a protocol called SICA-PED (i.e. Safe Insertion of Central Access in Pediatric patients) and includes seven evidence-based strategies. Through a single-center prospective observational study, the authors wanted to consolidate the efficacy and safety of these protocol in newborns. In a series of 104 newborns, the seven steps of the protocol were applied (1) pre-procedural ultrasound study of the RaCeVA veins, (2) correct aseptic technique, (3) ultrasound-guided venipuncture, (4) intraprocedural localization of the tip of the catheter with TTE (ECHO TIP) and (iECG) intracavitary electrocardiogram, (5) reasoned choice of the implant exit site with the RAVESTO Tunneling technique, (6) anchoring without stitches, and (7) exit point protection with the use of glue and transparent semipermeable membrane. The authors have included a further precaution in point (6) the subcutaneous anchoring system has added the counter-fixation of the catheter wings that we will call 6Plus Point. All infants requiring implantation of elective us-guided central venous access were enrolled in the study. None of the 104 implanted central venous catheters experienced early complications (accidental arterial puncture, PNX, primary malposition); rare late complications such as ecchymosis, CRBSI, exit site infection or dislodgement were observed, No catheter-related thrombotic phenomena were observed. The CRBSI catheter-related infection rate was 2.47 × 1000 days catheter cases. The results of this prospective study strengthen the feasibility and efficacy of the SICA-Ped Protocol. Demonstrating that the systematic application of the evidence-based seven-step implantation strategy increases the success rate, minimizes early and late complications, which result in increased patient safety.

Semi–Bone Tunnel Technique Using Double-Row Suture Bridge Combined With Platelet-Rich Plasma Hydrogel for Rotator Cuff Repair in a Rabbit Model

Background: The approach to managing the footprint area and reconstructing the tendon-bone interface (TBI) is critical for optimal healing. Purpose: To evaluate the outcomes of the semi–bone tunnel (SBT) technique using a double-row suture bridge combined with platelet-rich plasma (PRP) hydrogel for rotator cuff repair in a rabbit model. Study Design: Controlled laboratory study. Methods: A total of 48 New Zealand White rabbits were divided into 4 groups. The supraspinatus tendons were severed at the footprint to create a rotator cuff tear model in the surgical groups. Rabbits were treated with the traditional onto-surface repair (control group), SBT technique (SBT group), and SBT technique combined with PRP hydrogel implantation (SBT+PRP group). The rabbits without surgery were the normal group. At 8 weeks after surgery, macroscopic observation, magnetic resonance imaging (MRI) and micro–computed tomography (μCT) examinations, histological evaluations, and biomechanical tests were performed to assess the curative effects of the given treatments. Results: The MRI results showed that the repaired supraspinatus tendon presented a uniform signal, minimal inflammatory response, and the lowest signal-to-noise quotient value in the SBT+PRP group. The μCT results suggested that the SBT technique did not reduce the local bone mineral density in the TBI area compared with the onto-surface repair technique. The histological staining results showed that the regenerated TBI in the SBT+PRP group had a 4-layer structure similar to the natural tissue. The highest values for biomechanical properties were observed in the SBT+PRP group, and there was no significant difference between the SBT+PRP group and normal group. Conclusion: The SBT technique presented a better tendon-bone healing effect for rotator cuff tear in the rabbit model compared with the traditional onto-surface repair technique. The specimens in the SBT+PRP group had a similar TBI structure and biomechanical properties to the natural tissue. Clinical Relevance: The SBT technique can be an alternative surgical approach for rotator cuff repair, especially for moderate to large tears and cases requiring scaffold implantation.
