Development and validation of a novel method for assessing physical activity profiles after anterior cruciate ligament reconstruction: The Sports and Physical Activity scale.

Objectives: To describe and evaluate the preliminary validity of a novel scoring system for assessing the physical activity of patients after anterior cruciate ligament (ACL) reconstruction.

Methods: The Sports and Physical Activity (SPA) scale consists of thirty options of sports and physical activities, followed by four frequency options for each option selected. Factors used to develop the scoring system were frequency of participation and intensity of the sports or physical activities.

Responsiveness of the Various Short-Form Versions of the Knee Injury and Osteoarthritis Outcome Score Between 2 and 5 Years After Anterior Cruciate Ligament Reconstruction.

Background: Various short-form versions of the Knee injury and Osteoarthritis Outcome Score (KOOS) have been developed in an attempt to minimize responder burden. However, the responsiveness of these short-form measures in patients who have undergone anterior cruciate ligament (ACL) reconstruction has not been compared at midterm follow-up.

Purpose: To determine the responsiveness of 3 short-form versions of the KOOS (KOOS-12, KOOS-Global, and KOOS-ACL) in patients who have undergone ACL reconstruction.

Flow and outdoor adventure recreation: Using flow measures to re-examine motives for participation.

Adventure participants have traditionally been viewed as having thrill or risk-seeking motives, and this perception remains despite empirical research suggesting that other motives may drive participation. This study was conducted to extend understanding of participation motives of adventure recreation participants in relation to Csiksentmihalyi's nine-dimension model of flow and other proposed motivational constructs. Participants (n = 199) who had typically engaged in their adventure recreation activity (i.

Psychological Flow Training: Feasibility and Preliminary Efficacy of an Educational Intervention on Flow.

Unlabelled: Despite there being an increasing number of applied flow studies across scientific disciplines, there exists no consistent or broadly applicable intervention to promote flow experiences. This study provides a detailed account of a new educational flow training program developed following recent advancements in the flow literature that have provided a more parsimonious understanding of flow experiences and antecedents. Guided by CONSORT guidelines for feasibility trials, we conducted a single-group, non-randomized feasibility trial of an educational flow training program ( 26).

Advancing our understanding of psychological flow: A scoping review of conceptualizations, measurements, and applications.

Research on psychological flow is well established, although criticisms remain regarding conceptual and measurement issues associated with the construct. This scoping review maps flow-related research across scientific disciplines, examining the conceptualization, measurement instruments, and outcomes of flow between 2012 and 2019. Across 236 sources that met the review criteria, 108 different flow-related constructs were measured by 141 instruments, and 84 possible antecedents were identified.

Mesenchymal stem cell therapy combined with arthroscopic abrasion arthroplasty regenerates cartilage in patients with severe knee osteoarthritis: a case series.

To evaluate the safety and efficacy of adipose-derived mesenchymal stem cell (ADMSC) therapy in combination with arthroscopic abrasion arthroplasty (AAA) in advanced knee osteoarthritis (OA). 27 patients with Grade IV OA of the knee underwent AAA and ADMSC therapy (50 × 10 ADMSCs at baseline and 6 months). Clinical outcome was assessed over 36 months.

Evaluation of autologous adipose-derived mesenchymal stem cell therapy in focal chondral defects of the knee: a pilot case series.

To evaluate the safety, pain, functional and structural improvements after autologous adipose-derived mesenchymal stem cell (ADMSC) therapy in combination with arthroscopic abrasion arthroplasty in focal chondral defects of the knee. Eight patients with a focal full thickness chondral defect of the knee underwent arthroscopic abrasion arthroplasty followed by postoperative intra-articular injections of autologous ADMSCs (50 × 10 ADMSCs at baseline and 6 months). Clinical outcome was assessed using numeric pain rating scale, Knee Injury and Osteoarthritis Outcome Score and the Western Ontario and McMaster Universities Osteoarthritis Index.

Primary ACL reconstruction using the LARS device is associated with a high failure rate at minimum of 6-year follow-up.

Purpose: The Ligament Augmentation and Reconstruction System (LARS) is a synthetic ligament consisting of fibres made of polyethylene terephthalate. Despite the LARS being used as an anterior cruciate ligament (ACL) device for nearly 30 years and the well-documented complications from earlier synthetic ligament designs, there is a paucity of published medium- to long-term results. The aim of this study is to report the clinical and functional outcomes after ACL reconstruction using the LARS at a minimum follow-up of 6 years.

High tibial osteotomy in combination with arthroscopic abrasion arthroplasty and autologous adipose-derived mesenchymal stem cell therapy in the treatment of advanced knee osteoarthritis.

Osteoarthritis is a progressive and debilitating condition. An increasing number of total knee replacements are being performed under the age of 65. Improved understanding of the action of mesenchymal stem cells (MSC) has seen renewed interest in their role in cartilage repair.

Synovitis following anterior cruciate ligament reconstruction using the LARS device.

Purpose: The Ligament Augmentation and Reconstruction System (LARS) has been at the forefront of a recent revival in the use of synthetic ligaments for ACL reconstruction. However, despite promising short-to-mid-term results its role has been approached with caution due to a high number of major complications in previous synthetic graft designs including mechanical failures, synovitis and osteoarthritis. This study aims to report on the incidence of synovitis in a series of patients undergoing second-look surgery following LARS ACL reconstruction.

Comparison of health literacy in privately insured and public hospital orthopaedic patients.

Objective The aim of the present study was to quantify and compare patient health literacy between privately insured and public orthopaedic patients. Methods As part of the present cross-sectional study, elective postoperative orthopaedic patients across two sites were recruited and asked to complete a questionnaire at the first postoperative out-patient review. Patients were divided into three groups: (1) a public group (Public); (2) a private group (Private-pre); and (3) a private group that completed the questionnaire immediately after the out-patient review (Private-post).

Adipose derived mesenchymal stem cell therapy in the treatment of isolated knee chondral lesions: design of a randomised controlled pilot study comparing arthroscopic microfracture versus arthroscopic microfracture combined with postoperative mesenchymal stem cell injections.

Introduction: The management of intra-articular chondral defects in the knee remains a challenge. Inadequate healing in areas of weight bearing leads to impairment in load transmission and these defects predispose to later development of osteoarthritis. Surgical management of full thickness chondral defects include arthroscopic microfracture and when appropriate autologous chondrocyte implantation.

Synthetic devices for reconstructive surgery of the cruciate ligaments: a systematic review.

Purpose: The role of synthetic devices in the management of the cruciate ligament-injured knee remains controversial. The aim of this systematic review was to assess the safety and efficacy of synthetic devices in cruciate ligament surgery.

Methods: A systematic review of the electronic databases Medline, Embase, and The Cochrane Library (issue 1, 2014) on January 13, 2014, was performed to identify controlled and uncontrolled trials.
