onservative therapy remaining the mainstay of treatment.Background  Compared with anatomic total shoulder arthroplasty (aTSA), reverse total shoulder arthroplasty (RTSA) is associated with lower preoperative and postoperative outcome scores and range of motion. It is unknown whether patients' preoperative expectations of surgery are lower in RTSA compared with aTSA. The purpose of this study was to assess preoperative patient expectations and postoperative outcomes in aTSA and RTSA. Methods  A consecutive series of patients undergoing primary aTSA for diagnosis of osteoarthritis or primary RTSA for diagnosis of rotator cuff tear arthropathy were studied prospectively. Expectations were evaluated using the validated Hospital for Special Surgery's Shoulder Surgery Expectations Survey. Baseline demographics, comorbidities, and social factors were collected. Baseline and 2 years postoperative American Shoulder and Elbow Surgeons (ASES) score, visual analog scale pain, Single Assessment Number Evaluation (SANE), and patient satisfaction were obtained. Results  There wes positively correlated with postoperative functional outcomes. Level of Evidence  Level II, prospective cohort study.Background  Discoid lateral meniscus is the most frequent variant of the meniscus. Few studies have focused on the histology of discoid menisci. The aim of the present study was to report the histological findings of discoid lateral meniscus in children and adolescents, after arthroscopic partial resection, to give a possible explanation of its developmental etiology. Methods  Five patients aged 9, 10, 13, 15, and 17 years were operated on for a 1-piece excision of a discoid lateral meniscus, and the specimens were histologically examined. Results  The extracellular matrix showed a different distribution and characteristics depending on the different side of the meniscus. Irregularly oriented collagen fibers in discoid lateral meniscus were found. Cells of different shapes were observed depending on the surficial or deep location in the tissue. There were no blood vessels in the inner part of discoid lateral meniscus. Conclusion  The findings of the current study seem to confirm that discoid lateral meniscus arises from variant morphogenesis. Furthermore, the altered distribution and shape of the cells and disorganization of collagen fibers (irrespectively of the age of the patients) may predispose discoid lateral meniscus to degeneration, damage, and tear in young patients also. Level of Evidence  Level of evidence 4 (case series).Purpose  To evaluate the relationship between kinesiophobia and patient's return to sport after shoulder stabilization surgery. The hypothesis was that kinesiophobia represents an independent factor correlated to the difference between preinjury and postoperative level of sport. Methods  This study retrospectively evaluated 66 patients (mean age 35.5, standard deviation [SD] = 9.9 years) and at a mean follow-up of 61.1 (SD = 37.5) months after arthroscopic Bankart's repair or open Bristow-Latarjet procedure. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK); return to the preinjury sport was assessed by the difference between baseline and postoperative degree of shoulder involvement in sport (D-DOSIS) scale. The Western Ontario Shoulder Instability index (WOSI) was used to evaluate participants' perceptions of shoulder function. Results  TSK showed correlation with D-DOSIS ( ρ  = 0.505, p  less then  0.001) and the WOSI score ( ρ  = 0.589, p   less then  0.001). There was significant difference in TSK and WOSI scores between participants who had and had not returned to their previous level of sport participation ( p  = 0.006, and 0.0001, respectively). Conclusion  This study demonstrated that kinesiophobia is correlated to the return to sport after shoulder stabilization surgery. Level of Evidence  Level IV, retrospective case series.Purpose  This article compares short-term outcomes of two series of patients, who underwent reverse total shoulder arthroplasty (RTSA) with two different implants, both based on Grammont's principles the Delta III (D-3) and the Delta Xtend (D-XT) prostheses. Methods  The D-3 group included a consecutive series of 26 patients (mean age 75 years), that were treated between 2000 and 2006; the D-XT group included a consecutive series of 31 patients (mean age 72.5 years), for a total of 33 implants performed between 2011 and 2015. In both groups the most common diagnoses were cuff tear arthropathy (18 and 22 shoulders, respectively) and malunion of proximal humerus fractures (3 and 5). All procedures were performed by the same surgeon. Constant-Murley score (CMS) was used to assess clinical and functional outcomes. Radiographic evaluation included the true anteroposterior and axillary views. Results  Twenty-three patients of the D-3 group and 22 patients (24 shoulders) of the D-XT group were evaluated at a mean follow-up of 42 months (range 26-84) and 44 months (range 26-66), respectively. Four complications occurred in the D-3 group (1 partial deltoid detachment, 1 dislocation, and 2 glenoid component loosening), while one early postoperative infection occurred in the D-XT group. Increases in elevation and CMS between preoperative and postoperative period were observed in both groups; only the D-XT group showed a slight improvement in rotations. The incidence of scapular notching was significantly different between the two groups 100% for D-3 and 22.2% for D-XT in patients with a minimum follow-up of 5 years. Conclusion  Prosthetic design evolution and greater acquaintance with this surgery have undoubtedly led to an improvement in short-term outcomes with second generation implants of RTSA. buy FI-6934 Future studies will have to ascertain whether newer implants, relying on biomechanical solutions alternative to Grammont's original concept, might provide additional advantages and minimize drawbacks.Purpose  The aim of this study was to evaluate the efficacy in terms of clinical results and radiographic findings of using metaphyseal sleeves in revision total knee arthroplasty (TKA), and to check if the use of sleeves without stems did not impair such results. Methods  In this retrospective study, 141 patients (143 knees) operated in the period 2008 to 2015 met the above-mentioned criteria and were invited to a medical examination including X-rays. A total of 121 knees were available for the study (44 in the group without stems and 77 in the group with stems). Mean follow-up was 63 months for the stemless group and 89 for the group with stems. Knee Society Score (KSS) (objective knee score) and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were used as outcome scores and compared with baseline values, range of motion (ROM) was also compared with preop value and X-rays were also examined and compared with immediate postop X-rays to check signs of loosening and radiolucent lines, if any, and bone ingrowth.
