Pneumatic compression device does not show effective thromboprophylaxis following total knee arthroplasty in a low incidence population.

Introduction: Purpose of this study was to assess whether the intermittent pneumatic compression (IPC) device would be an effective prophylaxis for deep vein thrombosis (DVT) following total knee arthroplasty (TKA) in a low incidence population.

Hypothesis: The mechanical thromboprophylaxis could reduce the incidence of DVT compared to non-prophylaxis group and would have similar efficacy as the chemoprophylaxis following TKA in a low DVT incidence population.

Materials And Methods: From January 2009 to June 2016, 1259 elective primary TKA with preoperative diagnosis of primary osteoarthritis in a single institute were enrolled.

Medial Open-Wedge High Tibial Osteotomy May Adversely Affect the Patellofemoral Joint.

Purpose: To evaluate 2-stage arthroscopic findings of the patellofemoral joint before and after medial open-wedge high tibial osteotomy (HTO) and verify whether the patellofemoral joint would be influenced by medial open-wedge HTO.

Methods: We prospectively reviewed 114 cases of medial open-wedge HTO for the treatment of osteoarthritis with a varus knee. First-look arthroscopy was performed during HTO.

Is Single-Radius Design Better for Quadriceps Recovery in Total Knee Arthroplasty?

Purpose: Although single-radius (SR) designs have a theoretical advantage in quadriceps recovery following total knee arthroplasty (TKA), there has been a paucity of objective evaluation studies.

Materials And Methods: One hundred and twenty minimally invasive TKAs were prospectively randomized by a single surgeon into 2 groups: SR design TKA group and multi-radius design TKA group. Quadriceps force and power were assessed using a dynamometer, and clinical data were investigated preoperatively and 6 weeks, 3 months, 6 months and 1 year postoperatively.

Are Korean Patients Different from Other Ethnic Groups in Total Knee Arthroplasty?

Most of the implants used for total knee arthroplasty (TKA) in Asian patients have been produced based on anthropometry of Western people. Since anatomic features and life styles are different between Western and Eastern people, there would be ethnic differences in terms of conformity of implants to the patient's anatomy or clinical results after TKA. Therefore, surgeons in Asia are particularly interested in related surgical techniques and implant designs used in TKA for improved clinical results and patient satisfaction.

Characterization of a CK II protein kinase from etiolated oat seedlings.

Protein kinases play a central role in controlling the cellular metabolism of living organisms. A protein kinase was purified from etiolated oat seedlings by several steps of ion-exchange and affinity chromatographies. The kinase was a 150-kDa tetrameric protein and composed of three subunits of 34, 37, and 40 kDa proteins.
