Midfoot sprains in athletes represent a spectrum of injuries to the Lisfranc ligament complex, from partial with no displacement complete tears frank diastasis. Treatment these varies treatment high-velocity seen nonathletes.We wanted report outcome classified according our system.Retrospective cohort study.Weightbearing radiographs and bone scintigrams were used diagnose midfoot 15 who treated surgically or nonoperatively following classification: nonoperative management for stage I...
Objectives: To investigate the incidence and demographic features of anterior cruciate ligament (ACL) reconstructions in Australia by age sex, to determine whether has changed during past 15 years. Design setting: Descriptive epidemiological analysis longitudinal data on ACL (July 2000 – June 2015) National Hospital Morbidity Database. Main outcome measures: Population reconstruction rates, group sex. Results: 197 557 primary were performed study period; annual increased 43% (from 54.0 77.4...
Background: The hamstring tendon graft used in anterior cruciate ligament (ACL) reconstruction has been shown to lead changes the semitendinosus and gracilis musculature. Hypothesis: We hypothesized that (1) loss of donor muscle size would significantly correlate with knee strength deficits, (2) be greater for muscles do not experience regeneration, (3) morphological adaptations also evident nondonor muscles. Study Design: Cross-sectional study; Level evidence, 3. Methods: Twenty...
Background: Although there is a known correlation between obesity and revision risk following total knee arthroplasty (TKA), an ongoing debate regarding the appropriateness of denying TKA solely based on body mass index (BMI) patient. Our aim was to determine whether patient’s American Society Anesthesiologists (ASA) class predicts their risks early all-cause for periprosthetic joint infection (PJI) primary TKA, independent BMI. Methods: Data from Australian Orthopaedic Association National...
To investigate differences in anterior cruciate ligament-reconstructed (ACLR) and healthy individuals terms of the magnitude tibiofemoral contact forces, as well relative muscle external load contributions to those during walking, running, sidestepping gait tasks.A computational EMG-driven neuromusculoskeletal model was used estimate forces with single-bundle combined semitendinosus gracilis tendon autograft ACLR (n = 104, 29.7 ± 6.5 yr, 78.1 14.4 kg) controls 60, 27.5 5.4 67.8 14.0 walking...
Controversy still exists as to the optimum management of posterior cruciate ligament (PCL) in total knee arthroplasty. Surgeons can choose kinematically substitute PCL with a posterior-stabilized replacement or alternatively utilize cruciate-retaining, also known minimally stabilized, replacement. Proponents propose that reported lower survivorship registries when directly compared stabilized is due confounders such selection bias because preferential usage more complex severe cases. In this...
The aim of this study was to investigate the relationship obesity with all-cause revision and for infection, loosening, instability, pain after total knee arthroplasty (TKA) performed in Australia.Data patients undergoing primary TKA osteoarthritis from January 1, 2015, December 31, 2020, were obtained Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR). rates compared non-obese (body mass index [BMI], 18.50 29.99 kg/m 2 ), class-I II obese (BMI, 30.00 39.99...
Reports of nonunion proximal fifth metatarsal fractures treated by internal fixation indicate that current methods do not always adequately address the stresses to which bone is subjected during ambulation. In particular, insertion sites peroneus brevis and tertius tendons on suggest their actions can impose torsional areas in Jones stress occur. Intramedullary screw fixation, however, offers little resistance rotation distal fragments relative one another.To determine potential for...
Infection after ACL reconstruction is uncommon but catastrophic. Prophylactic graft saturation in vancomycin reportedly reduces infection rates.We characterized elution from soaked tendons. Specifically, the effect of rinsing was studied. We also determined how concentration soak solution and tendon dimension influenced this rate, examined whether amount released lower than osteoblast chondroblast toxic concentrations.Bovine tendons were wrapped sterile gauze swabs presoaked with 5-, 2.5-,...
Update This article was updated on March 8, 2017, because of a previous error. On page 275, in the Results section abstract, sentence that had read “No difference HR for revision risk found between Oxinium and CoCr cohorts any age category all causes (HR = 0.92 [95% confidence interval (CI), to 1.29]; p 0.329), loosening or lysis, aseptic causes, except lysis group patients who were ≥75 years old (p 0.033)” now reads 0.78 1.08]; 0.033).” 276, Figure 1, text “Entire Period: (0.92, 1.29),...
Background The muscle-tendon properties of the semitendinosus (ST) and gracilis (GR) are substantially altered following tendon harvest for purpose anterior cruciate ligament reconstruction (ACLR). This study adopted a musculoskeletal modelling approach to determine how changes ST GR alter their contribution medial compartment contact loading within tibiofemoral joint in post ACLR patients, extent which other muscles compensate under same external conditions during walking, running sidestep...
Background Knee osteoarthritis (OA) patients often suffer joint pain and stiffness, which contributes to negative changes in body composition, strength, physical performance (function), activity health-related quality of life. To reduce these symptoms side effects knee OA, moderate-intensity continuous training (MICT) cycling is recommended. While resistance considered the optimal form improve sarcopenic outcomes, it imposes higher loads requires supervision, either initially or continuously...
Despite suggestions that tourniquet inflation during total knee replacement reduces bleeding and hence improves cement penetration, no studies exist supporting this widely held belief. In single-blinded, single-surgeon, randomized controlled trial, the cementation group ( n = 20) did not have greater tibial penetration compared to a 20). No statistically significant differences in semiautomatic digitally measured average central radiographic plateau values were observed between two groups p...
The optimum strategy regarding resurfacing the patella in total knee replacement (TKR) remains debated, with wide national and international variability. To minimize confounders of a direct comparison cases or without resurfacing, we performed an instrumental variable analysis examining revision risk on basis surgeon preference for patellar TKR, specifically subsequent all-cause among surgeons preferring to perform selective compared those whose is routinely resurface who infrequently...
Background/aim Anterior cruciate ligament (ACL) injury is a common and devastating sporting injury. With or without ACL reconstruction, the risk of knee osteoarthritis (OA) permanent disability later in life markedly increased. While neuromuscular training programmes can prevent 50–80% injuries, no national implementation strategies exist Australia. The aim this study was to compare ability four alternative universal prevention programme reduce future medical costs secondary Methods A Markov...
