Dynamic Hip Kinematics During the Golf Swing After Total Hip Arthroplasty
American Journal of Sports Medicine - Tập 44 Số 7 - Trang 1801-1809 - 2016
Daisuke Hara, Yasuharu Nakashima, Satoshi Hamai, Hidehiko HIGAKI, Satoru Ikebe, Takeshi SHIMOTO, Kensei Yoshimoto, Yukihide Iwamoto
Background: Although most surgeons allow their patients to play golf after total hip arthroplasty (THA), the effect on the implant during the golf swing is still unclear. Purpose: To evaluate hip kinematics during the golf swing after THA. Study Design: Descriptive laboratory study. Methods: Eleven hips in 9 patients who underwent primary THA were analyzed. All patients were right-handed recreatio... hiện toàn bộ
One-Year Follow-up of Platelet-Rich Plasma Treatment in Chronic Achilles Tendinopathy
American Journal of Sports Medicine - Tập 39 Số 8 - Trang 1623-1630 - 2011
Suzan de Jonge, Robert‐Jan de Vos, Adam Weir, Hans T. M. van Schie, Sita M.A. Bierma‐Zeinstra, Jan A.N. Verhaar, H. Weinans, Johannes L Tol
Background Achilles tendinopathy is a common disease among both athletes and in the general population in which the use of platelet-rich plasma has recently been increasing. Good evidence for the use of this autologous product in tendinopathy is limited, and data on longer-term results are lacking. Purpose To study the effects of a platelet-rich plasma injection in patients with chronic midportion... hiện toàn bộ
Autologous Platelets Have No Effect on the Healing of Human Achilles Tendon Ruptures
American Journal of Sports Medicine - Tập 39 Số 1 - Trang 38-47 - 2011
Thorsten Schepull, Joanna Kvist, Hanna Norrman, Marie Trinks, Gösta Berlin, Per Aspenberg
Background: Animal studies have shown that local application of platelet-rich plasma (PRP) stimulates tendon repair. Preliminary results from a retrospective case series have shown faster return to sports. Hypothesis: Autologous PRP stimulates healing of acute Achilles tendon ruptures. Study Design: Randomized controlled trial; Level of evidence, 2. Methods: Thirty patients were recruited consecut... hiện toàn bộ
Comparison of Growth Factor and Platelet Concentration From Commercial Platelet-Rich Plasma Separation Systems
American Journal of Sports Medicine - Tập 39 Số 2 - Trang 266-271 - 2011
Tiffany N. Castillo, Michael A. Pouliot, Hyeon Joo Kim, Jason L. Dragoo
Background: Clinical studies claim that platelet-rich plasma (PRP) shortens recovery times because of its high concentration of growth factors that may enhance the tissue repair process. Most of these studies obtained PRP using different separation systems, and few analyzed the content of the PRP used as treatment. Purpose: This study characterized the composition of single-donor PRP produced by 3... hiện toàn bộ
Treatment of Chronic Elbow Tendinosis with Buffered Platelet-Rich Plasma
American Journal of Sports Medicine - Tập 34 Số 11 - Trang 1774-1778 - 2006
Allan Mishra, Terri Pavelko
Background Elbow epicondylar tendinosis is a common problem that usually resolves with nonoperative treatments. When these measures fail, however, patients are interested in an alternative to surgical intervention. Hypothesis Treatment of chronic severe elbow tendinosis with buffered platelet-rich plasma will reduce pain and increase function in patients considering surgery for their problem. Stud... hiện toàn bộ
Platelet-Rich Plasma Versus Autologous Whole Blood for the Treatment of Chronic Lateral Elbow Epicondylitis
American Journal of Sports Medicine - Tập 39 Số 10 - Trang 2130-2134 - 2011
C. Thanasas, George N. Papadimitriou, Charalambos Charalambidis, I. Paraskevopoulos, Athanasios Papanikolaou
Background: Chronic lateral elbow epicondylitis is a tendinosis with angiofibrolastic degeneration of the wrist extensors’ origin. Healing of this lesion is reported with the use of autologous blood as well as with platelet-rich plasma (PRP). Purpose: A comparative study of these 2 treatments was conducted in an effort to investigate the possible advantages of PRP. Study Design: Randomized control... hiện toàn bộ
Platelet-Rich Plasma Augmentation for Arthroscopic Rotator Cuff Repair
American Journal of Sports Medicine - Tập 39 Số 2 - Trang 258-265 - 2011
Roberto Castricini, Umile Giuseppe Longo, Massimo De Benedetto, N. Panfoli, Piergiorgio Pirani, Raul Zini, Nicola Maffulli, Vincenzo Denaro
Background: After reinsertion on the humerus, the rotator cuff has limited ability to heal. Growth factor augmentation has been proposed to enhance healing in such procedure. Purpose: This study was conducted to assess the efficacy and safety of growth factor augmentation during rotator cuff repair. Study Design: Randomized controlled trial; Level of evidence, 1. Methods: Eighty-eight patients wit... hiện toàn bộ
Platelet Activation by Collagen Provides Sustained Release of Anabolic Cytokines
American Journal of Sports Medicine - Tập 39 Số 4 - Trang 729-734 - 2011
Sophia L. Harrison, Patrick Vavken, Sherwin V. Kevy, May S. Jacobson, David Zurakowski, Martha M. Murray
Background: Platelet-rich plasma (PRP) has been increasingly used in sports medicine applications. Platelets are thought to release growth factors important in wound healing, including transforming growth factor (TGF-β1), platelet-derived growth factor (PDGF-AB), and vascular endothelial growth factor (VEGF). However, little is known about the effect of platelet activator choice on growth factor r... hiện toàn bộ
Ongoing Positive Effect of Platelet-Rich Plasma Versus Corticosteroid Injection in Lateral Epicondylitis
American Journal of Sports Medicine - Tập 39 Số 6 - Trang 1200-1208 - 2011
Taco Gosens, Joost C. Peerbooms, Wilbert van Laar, Brenda L. Den Oudsten
Background: Platelet-rich plasma (PRP) has been shown to be a general stimulation for repair and 1-year results showed promising success percentages. Purpose: This trial was undertaken to determine the effectiveness of PRP compared with corticosteroid injections in patients with chronic lateral epicondylitis with a 2-year follow-up. Study Design: Randomized controlled trial; Level of evidence, 1. ... hiện toàn bộ
