Methods: In this study, we utilised three most widely used search tools in the form of Google Scholar (GS), Web of Science (WoS), and Scopus (Sco) with the keyword search of Shoulder Surgery to identify articles relevant to the field of shoulder surgery. We selected and analysed the 200 most frequently cited articles in this field. The articles were included in our database based on titles and abstract analysis. Statistical analysis was used to characterise citation number, citation index, Source journal, author frequency, type of study and levels of evidence. Results: The 200 most cited articles were published between 1923 and 2012. The decades of 2000's (36%) followed by 1990's (33%) were the most productive era of the articles. All the articles were written in English except for one in French and were published in forty journals. The majority of articles originated from United States, followed by France and Switzerland. Articles related to rotator cuff (18%) and Instability (17.5%) were the most discussed topics. Most cited articles were clinical series, the most common level of evidence was level IV. Only a small percentage of articles utilized patient rated outcome measures. GS consistently found the largest percentage of citations across all areas, far ahead of Scopus and WoS. Conclusions: The field of shoulder surgery has witnessed numerous milestones and this article identifies and analyses the most frequently cited articles in this field. Our data show that despite recent advancements in this field, most highly cited studies are of low-level evidence.

We propose in this chapter to describe the Lafosse subscapularis tears classification and to describe the arthroscopic repair that can be performed easily with a needle as shuttle. The advantages of these surgical techniques are simplicity, safety and quickness. The procedure is performed under general anaesthesia with the patient in beach chair position. A classic arthroscopic posterior portal is used to perform glenohumeral exploration, and cuff tendons are analysed. Once subscapularis tear is confirmed, the tendon must be released after repair with anterolateral portal. Then, a triple-loaded anchor is positioned at the edge of the bicipital groove to perform both biceps tenodesis and subscapularis repair.

Purpose: To determine whether outcomes of open Latarjet procedure (OLPs) depend on the level of sports practiced by patients and to report clinical scores and complication rates for OLP at a minimum follow-up of 2 years. Study Design: Cohort study; Level of evidence, 3. Methods: A retrospective comparative study was conducted for all patients who underwent OLP by the senior author (J.B.) between July 2007 and December 2012. The indication for OLP at the authors’ institution was a minimum of 2 episodes of dislocation and/or subluxation, a positive apprehension test result in the cocking position, an Instability Severity Index Score more than 2, and evidence of anterior instability lesions on computed tomography arthrograms.

Corticosteroid injections (CSIs) are frequently used as conservative treatments before surgical repair. This study aimed to determine the influence of preoperative and postoperative CSIs on clinical and anatomic outcomes after rotator cuff repair. Methods: The authors analyzed the records of 257 patients who had arthroscopic rotator cuff repair, of whom 212 were evaluated at 3.1 ± 1.0 years (median, 2.9 years; range, 1.4-7.1 years) by clinical (Constant score) and ultrasound (Sugaya classification) examinations. Univariable and multivariable regressions were performed to determine associations between outcomes and administration of preoperative and postoperative CSIs, patient characteristics, and tendon characteristics. Results: The Constant scores improved from 56.4 ± 15.1 to 80.8 ± 12.5. Multivariable regression confirmed that postoperative scores were associated with postoperative CSIs (P < .001), preoperative scores (P < .001), gender (P < .001), and fatty infiltration (P < .005). Retears (Sugaya types IV-V) were observed in 27 shoulders (13%). Multivariable regression clarified that retear rates were associated only with postoperative CSIs (P = .007) and stage 3 fatty infiltration (P = .001). Adjusting for confounders, an additional postoperative CSI would decrease scores by 4.7 points and double retear risks. Discussion: Preoperative CSIs had no influence on clinical scores and retear rates, whereas postoperative CSIs were associated with lower scores and more retears. Although we can infer that preoperative CSIs do not affect outcomes, we cannot determine whether postoperative CSIs compromised outcomes or were administered in patients who had already poor outcomes. Our findings may resolve controversies about the administration of preoperative CSIs.

We report an open reconstruction technique and its outcomes in a case of chronic and retracted PM tear. At the last follow-up (12 months), the patient was pain-free, with a visual analogic scale at 0 all the time. He was very satisfied concerning the cosmetic and clinical results. The constant score was 93%, the SST value 95%, and the Quick DASH score 4.5. MRI performed one year postoperatively confirmed the continuity between PM tendon and graft, even if the aspect of the distal tendon seemed to be thinner than normal PM tendon. The excellent clinical outcomes at one-year follow-up suggest that PM tear with major tendon retraction can be reliably reconstructed with hamstring autograft, using a bioabsorbable screw to optimize the fixation device. This technique has proven its simplicity and efficiency to fill the gap.

Fifteen postoperative CT scans were included to assess the intraobserver and interobserver reproducibility of a standardized protocol among 3 senior and 3 junior shoulder surgeons. The evaluation sequence included CG positioning, its contact area with the glenoid, and the angle of its screws in the axial plane. The percentage of CG positioned under the glenoid equator was also analyzed in the sagittal plane. The intraobserver and interobserver agreement was measured by the intraclass correlation coefficient (ICC), and the values were interpreted according to the Landis and Koch classification. The ICC was substantial to almost perfect for intraobserver agreement and fair to almost perfect for interobserver agreement in measuring the angle of...

Intrinsic factors as excessive tibial slope or narrow femoral notch increase failure risks but are rarely addressed in revision surgery. The authors report outcomes, at minimum follow-up of 2 years, for second revision ACL reconstructions combined with tibial deflexion osteotomy for correction of excessive slope (&amp;amp;amp;amp;amp;gt;12°). Nine patients that underwent second revision ACL reconstruction combined with tibial deflexion osteotomy were retrospectively studied. The mean age was 30.3 ± 4.4 years (median 28; range 26-37), and mean follow-up was 4.0 ± 2.0 years (median 3.6; range 2.0-7.6). Autografts were harvested from the quadriceps tendon (n = 8) or hamstrings (n = 1), and tibial osteotomy was done by anterior closing wedge, without detachment of the patellar tendon, to obtain a slope of 3° to 5°. All patients had fused osteotomies, stable knees, and there were no intraoperative or postoperative complications. The mean posterior tibial slope decreased from 13.2° ± 2.6° (median 13°; range 12°-18°) preoperatively to 4.4° ± 2.3° (median 4°; range 2°-8°) postoperatively. The mean Lysholm score was 73.8 ± 5.8 (median 74; range 65-82), and the IKDC-SKF was 71.6 ± 6.1 (median 72.8; range 62.2-78.5). The satisfactory results of second revision ACL reconstruction combined with tibial deflexion osteotomy at minimum follow-up of 2 years suggest that tibia slope correction protects reconstructed ACL from fatigue failure in this study. The authors stress the importance of careful analysis failure causes prior to revision ACL reconstruction, and recommend correction of tibial slope if it exceeds 12°, to reduce the risks of graft retear.

It is well known that in these cases the superior functional results depend on the restoration of the anatomy and stability of the AC joint in both vertical and horizontal planes. Considering the ligaments degeneration and atrophy in chronic AC joint dislocations, we present an arthroscopic-assisted reconstruction of both the coracoclavicular and AC ligaments using autograft augmentation. In details the coracoclavicular ligaments component is reconstructed using the Tightrope suspension device augmented with a palmaris longus autograft and by the nonanatomic coracoacromial ligament transfer (modified Weaver-Dunn). The AC part is restored by suturing the remainder palmaris longus autograft on the acromion and on the deltotrapezial fascia. Using the construct provided by this tec...
