NCT ID: NCT00493792 Completed - Clinical trials for Arthroplasty, Replacement, Knee

X-3 Polyethylene Survival Outcomes Study

Start date: February 2007
Phase: N/A
Study type: Interventional

A prospective, randomized, blinded clinical trial is proposed to compare Stryker Orthopaedics N2Vac Polyethylene to their X3 Polyethylene when used with the Triathlon Posterior Stabilized (PS) total knee system.

NCT ID: NCT00440921 Withdrawn - Clinical trials for Total Knee-replacement

Clinical Trial for Fibrin Sealant in Knee Surgery

Start date: December 2008
Phase: N/A
Study type: Interventional

- Thermogenesis is a company that sells a machine for the production of fibrin sealant of single donor plasma, the CryoSeal Fibrin Sealant System (CS-1). - Fibrin sealant consists of two components: cryoprecipitate and thrombin. Cryoprecipitate is the fraction of human plasma that contains concentrated coagulation factors, such as fibrinogen. Thrombin is an enzyme that facilitates the conversion of fibrinogen into fibrin, so that a clot will be formed. - Fibrin sealant can be used in surgery to increase hemostasis in the wound after e.g. knee- or hip replacement, cosmetical surgery or partial liverresections. - Until now, mainly autologous plasma was used to produce fibrin sealant with the CS-1. Within Sanquin there is a question whether fibrin sealant can be produced from the allogeneic quarantaine plasma that is in stock. Therefore in this study will be studied whether allogenous single donor fibrin sealant produced using the CS-1 is effective in wound healing and as consequence of this can be registered as a product of Sanquin. To answer these questions a national working party is formed, working party Fibrin Sealant. - So far, three man personnel in Sanquin Blood Bank Nort East Region (SBNO) are certified by Thermogenesis to use the CS-1 for production of fibrin sealant and an in vitro validation has been performed. - The next step will be a study for the in vivo effectiveness of fibrin sealant produced of single donor allogeneic quarantaine plasma using the CS-1. As control patients without fibrin sealant treatment will be studied. Two hospitals (Refaja Hospital in Stadskanaal and Wilhelmina hospital in Assen) are already interested in participating in this study. Probably, three more hospitals will participate. - The use of fibrin sealant will be studied in a prospective randomized trial for patients undergoing knee and hip replacements.

NCT ID: NCT00256958 Recruiting - Osteoarthritis Clinical Trials

Static and Dynamic Balance in Correlation With Quality of Life, in Primary Total Knee Replacement

Start date: November 2005
Phase: Phase 1/Phase 2
Study type: Interventional

Knee osteoarthritis (OA) is one of the most prevalent musculoskeletal complaints worldwide, affecting 30-40% of the population by the age of 65 yr.Individuals with knee OA suffer progressive loss of function.Balance is an integral component of these and many other activities of daily living. Individuals with knee OA display impairment in postural control, mostly under dynamic testing condition. Total knee replacement (TKR) has an established place in the treatment of knee osteoarthritis and is considered to be an effective intervention.It remains unknown whether TKR impact significantly at balance state of the patients with OA and whether improving in functional abilities after TKR correlates with balance control ability in this population.The purpose of this study is to determine whether TKR have any effects on relatively new postural control measures using force platform system - Balance master, in correlation with functional balance assessment. Methods: Participants During a year of prospective study we plan to recruit 150 participants with symptomatic OA of the knee, hospitalizing in orthopedic department of Hadassah Hospital for primary TKR. Participants will undergo evaluation just before a surgery and a year after.They will be asked to perform Balance Master measurements, ambulation and balance tests. Additional information will be collected through a questionnaire and physical examination.

NCT ID: NCT00160797 Withdrawn - Clinical trials for Total Knee Replacement

Total Knee Arthroplasty Outcome Study

Start date: August 2005
Phase: Phase 4
Study type: Interventional

The purpose of this study is to gather information about total knee replacement surgery using minimally invasive surgical procedures.

NCT ID: NCT00074828 Completed - Clinical trials for Total Knee Replacement

New Oral Anticoagulant Therapy for the Prevention of Blood Clots Following Hip or Knee Replacement Surgery

Start date: December 2003
Phase: Phase 2
Study type: Interventional

LY517717 (a capsule given by mouth) is a blood thinner that may prevent blood clots from forming in the legs and may prevent those blood clots from traveling to the lungs. Leg and lung blood clots occur commonly after patients have surgery to replace a hip or knee joint. These clots often occur while patients are in bed in the hospital after hip or knee joint surgery. The purpose of this study is to test if different dose strengths (amount of drug in the capsules) of LY517717 can prevent blood clots from forming and to determine if LY517717 is safe. This study will compare LY517717 to enoxaparin, another blood thinner. Enoxaparin is one of the standard medications given after hip or knee joint surgery.
