All-polyethylene (all-poly) tibial designs in primary total knee arthroplasty (TKA) have been reconsidered with excellent clinical outcomes, survivorship, and cost-effectiveness. However, whether all-poly tibial components provided comparable results to metal-backed modular components during unicompartmental knee arthroplasty (UKA) remains unclear. This study compared the clinical outcomes and prevalence of early failure between all-poly and metal-backed modular components in UKA. We retrospectively reviewed the records and radiographs of 101 consecutive UKAs...

The purpose of this randomized study was to compare clinical and surgical outcomes of total knee replacements (TKRs) in the early postoperative period using midvastus approach versus medial parapatellar approach in Asian population in a double blind manner. Forty-two knees each were operated using midvastus approach and the medial parapatellar approach. Clinical parameters that were evaluated included Knee Society score (KSS); knee pain using visual analogue scale (VAS) on day 1, 1 week, and 1 month; time required to straight leg raise (SLR); patellar tracking; mean extensor lag at 1 week and 1 month; and time of discharge from the hospital...

Frédéric Lavoie
Purpose Proper coronal and transverse ligament balancing is an important aspect of total knee arthroplasty (TKA) and has an impact on postoperative outcome. Many variations of the gap balancing technique were described to address this challenge, most of them using various tensioning devices, but none for which the use is widespread. The aim of this paper is to describe a gap technique variant for TKA using spacer blocks and report the clinical results for a cohort of patients on which it was used. Methods A total of 114 TKAs were performed in 101 patients using a standardized surgical technique that integrates ligament balancing with sizing and positioning of the femoral component...

Meniscal injuries are extremely common, with an incidence of 8.3 per 1,000 person/years in young, active individuals. Patients often turn to the internet to glean information about their injuries, and even to guide decision making about treatment. Much research has been done demonstrating that a reading level of eighth grade or lower is appropriate for accurately communicating written information to patients, yet medical practitioners often fail to meet this requirement. To better examine the information patients receive about meniscal injuries, we set out to evaluate the reading level and content of three commonly used search terms on the three search engines with the largest market share...

Novel graft types, fixation methods, and means for augmenting anterior cruciate ligament (ACL) reconstructions require preclinical validation prior to safe and effective clinical application. The objective of this study was to describe and validate a translational canine model for all-inside arthroscopic complete ACL reconstruction using a quadriceps tendon allograft with internal brace (QTIB). With institutional approval, adult research hounds underwent complete transection of the native ACL followed by all-inside ACL reconstruction using the novel QTIB construct with suspensory fixation (n = 10)...

Multiple therapies have been developed to slow down the progression of knee osteoarthritis (OA), with the aim of avoiding or delaying TKA. One such potential method is cell-mediated gene therapy, which utilizes allogeneic human chondrocytes modified to express transforming growth factor-β1. Using magnetic resonance imaging (MRI), we evaluated patients who underwent treatment with this injection in a Phase II study and assessed structural changes in: (1) bone marrow edema lesions, (2) cartilage defect depth and surface area, (3) articular bone surface and osteophytes, and (4) meniscus structure and signal, as well as changes in (5) joint fluid, (6) periarticular inflammation, and (7) synovial inflammation...

Alignment data in patient-specific instrumented (PSI) knee arthroplasty have been examined in several meta-analyses, with demonstration of comparative but not improved restitution of a neutral mechanical axis and favorable outcomes in femoral implant axial alignment. To date, no comprehensive synthesis of data has been conducted specifically for functional outcomes. Relevant databases were searched according to Preferred Reporting Items for Systematic reviews and Meta-analyses guidelines during the period 2000 to 2015 of Levels 1 and 2 studies comparing functional outcomes of patient-specific instrumentation (PSI) versus conventional instrumentation...

Control of knee motion in small animal models is necessary to study the effect of mechanical load on the healing process. This can be especially challenging in mice, which are being increasingly used for various orthopedic reconstruction models. We explored the feasibility of botulinum toxin (Botox; Allergan, Dublin, Ireland) paralysis and a newly designed external fixator to restrict motion of the knee in mice undergoing anterior cruciate ligament (ACL) reconstruction. Nineteen C57BL/6 mice were allocated to two groups: (1) Botox group (n = 9) and (2) external fixator group (n = 10)...

Total knee arthroplasty (TKA) is a widely accepted and successful procedure for end-stage arthritis. Nevertheless, fast-track may be compromised by many factors, such as pain, edema, and blood loss. Cryotherapy has been advocated as a safe and effective strategy to improve the postoperative results, acting on pain, edema, and blood loss. This study is a prospective randomized controlled study, involving 50 patients after primary TKA. A power analysis was performed preoperatively. Twenty-four patients were addressed to a postoperative treatment with a continuous cold flow device (Hilotherm, Hilotherm GmbH, Germany)...

Compared with staged bilateral total knee arthroplasty (TKA), simultaneous bilateral TKA carries a higher risk of cardiac complications, pulmonary complications, and mortality, especially in patients with preexisting cardiopulmonary disease or advanced age. However, the period of time between staged TKAs that would eliminate these increased risks has yet to be determined. The purpose of this study is to evaluate complication rates and functional outcome in patients who underwent staged bilateral TKA and to determine an optimal time frame for the second knee...

Much of the published works assessing the reliability of smartphone goniometer apps (SG) have poor generalizability since the reliability was assessed in healthy subjects. No research has established the values for standard error of measurement (SEM) or minimal detectable change (MDC) which have greater clinical utility to contextualize the range of motion (ROM) assessed using the SG. This research examined the test-retest reproducibility, concurrent validity, SEM, and MDC values for the iPhone goniometer app (i-Goni; June Software Inc...

This article aims to evaluate factors associated with chondral and meniscal lesions in primary and revision anterior cruciate ligament (ACL) reconstructions. ACL reconstructions from 2001 to 2008 at a single institution were retrospectively analyzed. Logistic regression was used to estimate the association between chondral and meniscal injuries and age, gender, tear chronicity, additional ligamentous injuries, sport type, and participation level. Of the 3,040 ACL reconstructions analyzed, 90.4% were primary reconstructions and 9...

We investigated the results of delirium which developed after total knee arthroplasty (TKA) and the risk factors for delirium in the patients who are older than 65 years. From March 2008 to March 2012, we performed a retrospective study on 296 knees of 265 patients who were treated with TKA. They were divided into two groups: 216 patients without delirium and 49 patients diagnosed with delirium by psychiatry. We analyzed the risk factors into three categories: First, the preoperative factors including gender, age, body mass index (BMI), clinical and functional knee joint score (Knee Society Knee Score and Knee Society Function Score) and the number of underlying diseases and associations with each disease; Second, the operative factors including the anesthesia method, amount of blood loss, operating time, laboratory factors, and transfusion count; Third, the postoperative factors such as start time of walking and duration of hospital stay were analyzed...

The rate of satisfaction after total knee arthroplasty (TKA) is consistently reported around 80%, leaving one in five patients unsatisfied to some extent. Fulfillment of expectations is reported as the strongest predictor of treatment satisfaction. In this study, we aimed to evaluate what Dutch orthopedic surgeons assume are realistic expectations for recovery 1 year after TKA. We invited the members of the Dutch Knee Society (DKS) to fill out a web-based questionnaire. For expectation measurement, the validated Dutch version of the Hospital for Special Surgery (HSS) knee replacement expectations survey was used...

Anterior cruciate ligament and meniscal injuries are associated with secondary osteoarthrosis which may lead to functional impairment and economic burden. The prevalence of knee injury has not been studied in depth. Our purpose was to report the prevalence of knee ligament and meniscal injuries and their associations with gender, body mass index (BMI), and height in young adults and to characterize individuals with meniscal injuries who gained full recovery. A cross-sectional, population-based study was conducted...

Anteromedial knee injury with rupture of anterior cruciate ligament (ACL) and concomitant lesion of medial collateral ligament (MCL) is common in athletes. No standardized treatment concept can be found within the literature. This study presents results of a new treatment concept for concomitant MCL lesions in patients with ACL rupture. In this study, 67 recreational athletes with ACL injury and concomitant MCL lesion were treated according to a distinct treatment concept. Patients were classified in six different types of concomitant MCL lesion depending on grade of MCL lesion and presence of anteromedial rotatory instability (AMRI)...
