Purpose The importance of meniscus integrity in the prevention of early osteoarthritis is well known, and preservation is accepted as the primary goal. The purpose of the ESSKA (European Society for Sports Traumatology, Knee Surgery and Arthroscopy) European consensus on traumatic meniscus tears was to provide recommendations for the treatment of meniscus tears based on both scientific evidence and the clinical experience of knee experts. Methods Three groups of surgeons and scientists elaborated and ratified the so-called formal consensus process to define the recommendations for the management of traumatic meniscus tears. A traumatic meniscus tear was defined as a tear with an acute onset of symptoms caused by a sufficient trauma. The expert groups included a steering group of eight European surgeons and scientists, a rating group of another nineteen European surgeons, and a peer review group. The steering group prepared twenty-seven question and answer sets based on the scientific literature. The quality of the answers received grades of A (a high level of scientific support), B (scientific presumption), C (a low level of scientific support) or D (expert opinion). These question and answer sets were then submitted to and evaluated by the rating group. All answers were scored from 1 (= totally inappropriate) to 9 (= totally appropriate) points. Thereafter, the comments of the members of the rating group were incorporated by the steering group and the consensus was submitted to the rating group a second time. Once a general consensus was reached between the steering and rating groups, the finalized question and answer sets were submitted for final review by the peer review group composed of representatives of the ESSKA-affiliated national societies. Eighteen representatives replied. Results The review of the literature revealed a rather low scientific quality of studies examining the treatment of traumatic meniscus tears. Of the 27 questions, only one question received a grade of A (a high level of scientific support), and another received a grade of B (scientific presumption). The remaining questions received grades of C and D. The mean rating of all questions by the rating group was 8.2 (95% confidence interval 8.1-8.4). A general agreement that MRI should be performed on a systematic basis was not achieved. However, MRI was recommended when arthroscopy would be considered to identify concomitant pathologies. In this case, the indication for MRI should be determined by a musculoskeletal specialist. Based on our data, stable left in situ lateral meniscus tears appear to show a better prognosis than medial tears. When repair is required, surgery should be performed as early as possible. Evidence that biological enhancement such as needling or the application of platelet-rich plasma would improve healing was not identified. Preservation of the meniscus should be considered as the first line of treatment because of an inferior clinical and radiological long-term outcome after partial meniscectomy compared to menis...

BackgroundHeterotopic ossification (HO) is a well-known complication after total hip arthroplasty (THA).Recently, the trend is to operate THA minimally invasive being less traumatic than standard approaches and promising a faster return to activity. The purpose of the study was to investigate if minimal invasive surgery (MIS), leads also to less HO after THA.MethodsThis retrospective study included 134 consecutive patients undergoing THA. In 42 (31.3%) patients a standard modified anterolateral (STD-Watson-Jones), in 28 (20.9%) patients a standard transgluteal Bauer approach (STD-Bauer), in 39 (29.1%) a MIS direct anterior approach (AMIS) and in 25 (18.7%) patients a MIS anterolateral (MIS-AL) approach was used. Standard preoperative anterior-posterior and lateral radiographs were assessed for occurrence of HO. HO was classified according to Brooker. In addition, short- and long-term adverse events were noted. Data was statistically analyzed using Chi-square tests, analysis of variance, multivariate data analysis and Pearson’s correlation (p < 0.05).ResultsOverall, HO was found in 38 caucasian patients (28.4%) after THA. The STD-Watson-Jones group showed the highest HO rate (45.2% n = 19) with a significant difference to the AMIS (23.1% n = 9) and STD-Bauer approach (14.3% n = 4). No statistical difference was found to the MIS-AL approach (24.0% n = 6). Postoperative complications did not differ significantly except for a higher incidence of Trendelenburg`s sign in STD-Bauer.ConclusionsThe rate and degree of HO after THA were significantly different with regards to the surgical approach. The standard modified anterolateral approach resulted in the highest HO rate, however, MIS approaches showed higher HO rates than the STD-Bauer.

Ligation of inferior mesenteric vessels does not seem to affect anastomotic healing; both surgical techniques presented similar incidence of anastomotic bleeding. In this analysis, we could not identify any significant difference in overall morbidity and mortality.

PurposeThe purpose of the present study was to correlate highly accurate CT measurements of pre-revision total knee arthroplasty (TKA) implant position with findings of retrieval analysis post-revision, to understand the clinical relevance of TKA orientation.MethodsThis study involved 53 retrieved TKA implants with pre-revision 3D-CT scans used to determine coronal (varus–valgus), sagittal (tibial slope) and rotational (internal rotation–external rotation) TKA orientation as well as tibiofemoral leg axis. Differences between femoral and tibial angles to describe the "relative rotational mismatch" were also calculated. All tibial inserts were forensically analyzed using the Hood score. Statistical analysis was performed to investigate correlations between TKA component orientation and surface damage (p < 0.05).ResultsFemoral components were found to have axial rotations mainly within ± 3° (68%), whilst 45% of the tibial components and 66% of the relative rotational mismatches were > 3° and < − 3°, respectively. The majority of femoral and tibial components (87% in both cases), as well as the femorotibial angle (70%), showed coronal orientations within ± 3°. The 64% of the tibial components showed posterior tibial slopes out of both the 0°–3° and 5°–7° ranges. There was a significant correlation between tibial slope and damage score on polyethylene tibial inserts (r = 0.2856; p = 0.0382) as well as a significant correlation between implants’ position in the axial plane and damage score on polyethylene tibial inserts (r = 0.6537, p = 0.0240).ConclusionsThis is the first study to use accurate measurements from pre-revision 3DCT to compare tibial and femoral orientation in all three planes with retrieval findings in total knee replacements. A significant correlation between implant position and polyethylene surface damage was found. These results showed the importance of optimizing component position to minimize polyethylene damage. Further analysis involving more accurate polyethylene wear measurements are fundamental to fully understand the role of components’ orientation in TKAs.

Background The benefit of a perianal block as an adjunct to general or regional anaesthesia is debated. This RCT aimed to compare pain at 24 h and up to 14 days after proctological surgery in patients with and without a perianal block. Methods Between January 2018 and April 2019, patients were allocated to receive a perianal block with ropivacaine or placebo as an adjunct to anaesthesia. Patients, surgeons and assessors were blinded. The primary outcome was pain measured on a numerical rating scale (NRS) after 24 h. Secondary outcomes were need for rescue analgesia, and pain after 1, 2, 3, 6 and 12 h. The mean, rest and maximum NRS scores were measured for 14 days. Results A total of 138 patients were included, of whom 46 and 44 received general anaesthesia with or without ropivacaine respectively, and 23 and 25 received spinal anaesthesia with or without ropivacaine respectively (P = 0·858). The mean NRS score differed significantly at 24 h (mean(s.d.) 1·1(0·1) versus 2·3(0·2); P < 0·001), but not at 1 h (1·4(0·2) versus 2·2(0·3); P = 0·051). The NRS score was lower with use of ropivacaine at 2 h (1·0(0·2) versus 1·6(0·2); P = 0·045), 3 h (0·9(0·2) versus 1·5(0·2); P = 0·022), 6 h (1·1(0·2) versus 1·8(0·2); P = 0·042) and 12 h (1·2(0·2) versus 1·8(0·2); P = 0·034). The use of oral morphine equivalents was 10·2(1·4) and 16·6(2·5) mg with and without ropivacaine respectively (P = 0·028). The mean and maximum NRS scores within 14 days were lower when ropivacaine was used (95 per cent c.i. for difference 0·14 to 0·49 (P = 0·002) and 0·39 to 0·63 (P < 0·001) respectively). There was no injection‐associated morbidity. Conclusion Perianal block as an adjunct to general or regional anaesthesia should be recommended for proctological surgery. It yields a reduction in pain, a reduced need for opioids, and a faster recovery with minimal risk of adverse events. Registration number: NCT03405922 ( http://www.clinicaltrials.gov).

Aim: Increasing attention has been given to postoperative gastrointestinal functional outcome and quality of life after sigmoid resection for diverticulitis. Conversely, very little has been described about postoperative urogenital functional outcome and even less about its potential relationship to the type of vascular approach. The aim of this study was to evaluate whether central ligation of the inferior mesenteric artery (IMA) compared with peripheral dissection could impair urinary and sexual function in the long term.Method: Patients undergoing elective laparoscopic sigmoid resection for diverticulitis from 2004 to 2017 were retrospectively analysed. They were asked to complete the American Urological Association Symptom Index (AUASI) questionnaire. Men received the five-item version of the International Index of Erectile Function (IIEF-5) questionnaire. Patients were then divided according to the type of vascular resection. Results:A response rate of the 36.4% to the AUASI and 43.8% to the IIEF-5 questionnaires was achieved. Three hundred and twenty four patients with a mean age of 62 ± 9.85 years were analysed for their urinary function (IMA preserved n = 217; IMA resected n = 107) in a median follow-up of 87 months. Furthermore, 115 men with a mean age of 60 ± 8.97 years were investigated for their sexual function (IMA preserved n = 80; IMA resected n = 35) in a median follow-up of 89 months. No difference (AUASI: 8 ± 6.32 IMA preserved vs. 7 ± 6.26

Higher BTU levels significantly correlated with symptoms, but a normal BTU could not exclude a specific pathology after THA. A threshold of BTU in SPECT/CT was identified to distinguish between symptomatic and asymptomatic patients after THA.
