KOL-Index: 11938 . BACKGROUND: Platelet-rich plasma (PRP) therapy has become an increasingly popular treatment for orthopaedics and sports-related injuries, and various clinically available PRP preparation methods exist. However, the differences in PRP quality among numerous preparation methods remain unclear. Specifically, the benefit of including leukocytes in the PRP product remains controversial, and few ...

KOL-Index: 10092 . PurposeDespite objectively good results, up to 70 % of individuals may not return to their pre-injury level of sports activity after anterior cruciate ligament (ACL) reconstruction surgery. Although psychological responses have been shown to affect outcomes after ACL injury, an appropriate means of measuring their effects, in addition to functional status, has not been determined. The ...

KOL-Index: 9224 . Background and purposePsychological factors including fear of pain, re-injury during movement (kinesiophbia) affect return-to-sport rates after anterior cruciate ligament (ACL) reconstructive surgery. Clinicians often encounter in the daily practice that athletes explain lack of self-confidence or psychological readiness during the sports activity. The Tampa Scale for Kinesiophobia (TSK) ...

KOL-Index: 7624 . BACKGROUND: Using intra-operative findings and clinical results, including return to play (RTP) at the pre-injury level, this study investigated the causes of primary graft failure after revision anterior cruciate ligament (ACL) reconstruction with bone-patellar-tendon-bone (BPTB) autografts. METHODS: A total of 54 patients were followed for a mean of 38.2 ± 10.2 months post-surgery. ...

KOL-Index: 7111 . PurposeTo identify unknown risk factors associated with fifth metatarsal stress fracture (Jones fracture).MethodsA case–controlled study was conducted among male Japanese professional football (soccer) players with (N = 20) and without (N = 40) a history of Jones fracture. Injury history and physical examination data were reviewed, and the two groups were compared. Univariate and ...

KOL-Index: 5910 . OBJECTIVES: Over a 11-year period, we investigated the incidence of anterior cruciate ligament (ACL) injuries and the clinical outcomes after ACL reconstruction with hamstring autografts in two homogenous cohorts of rugby players. METHODS: Two teams, including those in elite (94 players) and high school (290 players) clubs, were followed. RESULTS: Isolated ACL injuries occurred in 28 ...

KOL-Index: 5372 . Introduction: Researchers have investigated the use of platelet-rich plasma (PRP) therapy. However, the mechanisms through which PRP affects tissue repair remain unclear. We hypothesize that PRP promotes tissue repair through not only via direct manner on the local cells but also via indirect manner that encourage the recruitment of reparative cells such as macrophages (MPs), and it ...

KOL-Index: 3880 . BACKGROUND: Acute patellar tendon ruptures with poor tissue quality. Ruptures that have been neglected are difficult to repair. Several surgical techniques for the repair of the patellar tendon have been reported, however, these techniques remain difficult because of contractures, adhesions, and atrophy of the quadriceps muscle after surgery. CASE PRESENTATION: We report the cases of 2 ...

KOL-Index: 2729 . INTRODUCTION: Knee osteoarthritis (KOA), the most common form of osteoarthritis (OA) is a considerable health concern worldwide. Platelet-rich plasma (PRP) is a common therapeutic option for KOA. Different types of PRPs have varying efficacies. However, a comparative analysis of the qualities of these PRPs is lacking. METHODS: Two types of PRPs, including autologous protein solution (APS), ...

KOL-Index: 2312 . PURPOSE: Although platelet-rich plasma (PRP) therapy has become an increasingly popular treatment for sports-related injuries, the molecular mechanisms of PRP on tissue healing process remain poorly understood. The aim of the present study was to develop an experimental method quantifying the efficacy of PRP with murine patellar tendon injury model, leading to future elucidation of the ...

KOL-Index: 2158 . Introduction: Platelet-rich plasma (PRP) therapy is used to treat pathological conditions such as degenerative inflammatory diseases including osteoarthritis (OA) by enhancing tissue repair and promoting anti-inflammatory effects. Although PRP therapy for patients with knee OA improved pain and functional scores, the association of clinical outcomes and quality of PRP including cell ...

KOL-Index: 1721 . There has recently been growing interest worldwide in biological therapies such as platelet-rich plasma injection for the treatment of knee osteoarthritis. However, predicting the effectiveness of platelet-rich plasma therapy remains uncertain. Therefore, this retrospective cohort study was performed to assess a range of predictors for the effectiveness of platelet-rich plasma therapy in ...
