Posterior stability in posterior-stabilized vs medially congruent total knee replacement: A radiological comparison of two polyethylene designs in a single model:

Objective:The purpose of this radiological study was to assess the posterior laxity of a single model of a total knee arthroplasty design (TKA) having a medially constrained (MC) or a Posterior-Stabilized (PS) polyethylene insert using a well-documented stress x-ray. To the authors knowledge, this is the first report evaluating MC TKA outcomes according to the "kneeling view."Materials and Methods:Sixty patients with non-traumatic primary knee osteoarthritis undergoing TKA were first matched by age, sex, BMI and diagnosis and then divided in two groups: group A (37 knees) received a MC TKA and group B (23 knees) a PS implant made by the same manufacturer. In all cases the posterior cruciate ligament (PCL) was resected. All patients underwent the same postoperative "kneeling view" and were also clinically evaluated according to the Knee Society Score (KSS) and Oxford Knee Score (OKS). Radiographic measurements were taken by tracing a line along the posterior cortex of the tibia and then measuring the perpendicular distance to a point marked at the posterior corner of Blumensaat's line.Results:At 12 months minimum FU, no statistically significant differences were found between the two groups in all the clinical scores. There was a statistically significant difference on kneeling view values between the two groups (P = 0.0002): the mean value in the MC group was −1.97 ± 3.8 mm while was −5.6 ± 3.1 mm in the PS group. In both groups, the average position of the posterior cortex of the tibia was anterior to the posterior corner of Blumensaat's line, showing absence of instability in flexion.Conclusion:This study highlighted that the PCL removal, accompanied by a precise surgical technique, did not increase the instability in flexion in two groups of patients having the same TKA design but polyethylene inserts characterized by different levels of constraint

Anterior medial meniscal root tears: a novel arthroscopic all inside repair

Background: Management of tears of the anterior and posterior roots of the meniscus is still controversial. We wish to propose a simple technique of suture anchor to repair tears of the anterior root of the medial meniscus. Methods: Twelve patients, active males, underwent arthroscopic repair of the anterior meniscal horn between 2009 and 2011. All were assessed postoperatively at an average follow-up of 1 year after the index operation. Results: At the last appointment, the average Lysholm scores was improved from a pre-operative average value of 48±17 to a postoperative value of 91±7 (P<0.001); five patients (45.3%) were scored as excellent (≥95), and 7 (54.6%) as good (85–94). At the last appointment, 8 of 9 active patients practiced sport at the same preoperative level, 1 (8.5%) had changed to lower level of activity. No technique related complications were evident

I.S.Mu.L.T - Rotator cuff tears guidelines

Despite the high level achieved in the field of shoulder surgery, a global consensus on rotator cuff tears management is lacking. This work is divided into two main sessions: in the first, we set questions about hot topics involved in the rotator cuff tears, from the etiopathogenesis to the surgical treatment. In the second, we answered these questions by mentioning Evidence Based Medicine. The aim of the present work is to provide easily accessible guidelines: they could be considered as recommendations for a good clinical practice developed through a process of systematic review of the literature and expert opinion, in order to improve the quality of care and rationalize the use of resources

Recommendations on complementary feeding for healthy, full-term infants

Weaning (or introduction of complementary feeding) is a special and important moment in the growth of a child, both for the family and the infant itself, and it can play a major role in the child's future health. Throughout the years, various weaning modes have come in succession, the latest being baby-led weaning; the timing for introducing foods and the requirements of which sort of nutrient for weaning have also changed over time. Furthermore, the role played by nutrition, especially in the early stages of life, for the onset of later non-communicable disorders, such as diabetes, obesity or coeliac disease has also been increasingly highlighted. Members of Italian Society of Gastroenterology, Hepathology and Pediatric Nutrition (SIGENP) and the Italian Society of Allergology and Pediatric Immunology (SIAIP) Emilia Romagna here propose a practical approach for pediatricians to deal with daily practice. The four main areas for discussion were weaning in relation with the onset of allergic diseases, coeliac disease, diabetes and metabolic syndrome, the nutrition requirements to take into account for assessing the diet of infants under one year of age and about the practice of baby-led weaning focusing on limits and benefits, respectively

Transtendon repair in partial articular supraspinatus tendon tear

Introduction: Partial thickness rotator cuff tears (PTRCTs) are common, with an incidence between 17% and 37%, and a high prevalence in throwing athletes. Different surgical procedures are suggested when partial tears involve the articular portion of the rotator cuff, including arthroscopic debridement of the tear, debridement with acromioplasty, tear completion and repair, and lately transtendon repair. This systematic review describes the transtendon repair and examines indications, contraindications, complications and clinical outcome. Source of data: We identified clinical studies listed in the Pubmed Google Scholar, CINAHL, Cochrane Central and Embase Biomedical databases in English and Italian concerning the clinical outcomes following treatment of partial articular supraspinatus tendon tear using transtendon surgical repair. Areas of agreement: Eighteen studies fulfilled our inclusion criteria. All were published between 2005 and 2016, three were retrospective, and 15 prospective. The total number of patients was 507 with a mean age of 50.8 years. Areas of controversy: Tear completion and repair and transtendon repair alone produce similar results. Growing points: Transtendon surgical repair allows to obtain goodexcellent results in the treatment of partial articular supraspinatus tendon tears. Areas timely for developing research: Further studies are needed to produce clear guidelines in the treatment of partial articular supraspinatus tendon tears. Level of evidence: IV

Arthroscopic treatment of tibial eminence fracture: A systematic review of different fixation methods

Introduction Arthroscopy procedures are the gold standard for the management of tibial spine avulsion. This review evaluates and compares different arthroscopic treatment options for tibial spine fractures. Source of data PubMed, Medline, Ovid, Google Scholar and Embase databases were systematically searched with no limit regarding the year of publication. Areas of agreement An arthroscopic approach compared with arthrotomy reduces complications such as soft-tissue lesions, post-operative pain and length of hospitalization. Areas of controversy The use of suture techniques, compared to cannulated screw technique, avoids a second surgery for removal of the screws, but requires longer immobilization and partial weight bearing. Growing points Clinical outcomes and radiographic results do not seem to differ in relation to the chosen method of fixation. Areas timely for developing research Further studies are needed to produce clear guidelines to dene the best choice in terms of clinical outcomes, function and complications

Arthroscopic debridement of the ankle for mild to moderate osteoarthritis: A midterm follow-up study in former professional soccer players

Background: The aim of this study is to report the clinical and functional outcomes following arthroscopic management of anterior impingement, grade III-IV cartilage lesions, and mild to moderate osteoarthritis of the ankle in former soccer players. Methods: The study included 15 former male professional soccer players with mild to moderate degenerative changes of the ankle who had undergone arthroscopic debridement and management of secondary injuries of the ankle. Preoperatively and at the last follow-up, at an average of 7.4years, the American Orthopaedic Foot and Ankle Society (AOFAS) and the Kaikkonen scales and visual analogue scale (VAS) assessment were administered to all patients. Ankle osteoarthritis was assessed from weightbearing anteroposterior and lateral radiographs of both ankles. Results and discussion: At the last follow-up, the average AOFAS score had increased significantly from 48 (range, 29-69) to 86 (range, 63-94) (P<0.0001), with good to excellent scores in 11 patients (74%). The average Kaikkonen preoperative score of 43 (range, 28-70) had significantly improved to 85 (range, 61-95) (P<0.0001), with good excellent scores in 11 patients (74%). VAS values were also improved at the last follow-up. At the last appointment, only one (7%) patient had abandoned altogether any sport, as he did not feel safe with his ankle and he felt too old to continue. Conclusions: Anterior ankle arthroscopy for management of mild to moderate ankle arthritis is safe, effective, and low cost and allows former athletes to safely return to ordinary daily activities and recreational sport activities

Preoperative planning for ACL revision surgery

The number of patients undergoing revision surgery following failure of anterior cruciate ligament (ACL) reconstruction has increased over the recent past, following the overall increased number of primary ACL reconstruction performed. Failure of primary ACL reconstruction can be attributed to technical errors, biological failures, or new traumatic injuries. Technical errors include femoral and/or tibial tunnels malposition, untreated associated ligaments insufficiencies, uncorrected lower limb malalignment, and graft fixation failures. Candidates for revision surgery should be carefully selected, and the success of ACL revision requires precise preoperative planning to obtain successful results. Preoperative planning begins with the analysis of the mechanisms of ACL reconstruction failure, and information regarding previous surgery, such as the type of graft implanted, and the position of existing hardware. Appropriate imaging is necessary to evaluate the position of the femoral and tibial tunnels, and abnormal tunnel widening. On the basis of clinical examination and imaging, surgeon can perform an ACL revision procedure in 1 or 2 stages
