The NexGen legacy posterior stabilized (LPS) prosthesis was introduced in 1997 after many design changes to its predecessor, the Insall-Burstein II prosthesis. However, there have been no reported long-term studies on the performance of this implant. Prospectively, collected data from a local database comprising primary total knee replacements (TKRs) with LPS between 1997 and 2002 was analyzed. All implants were fixed with cement. Patients were followed up at 1, 3, 5, 7, and 10 years, with patient satisfaction, range of movement, and Knee Society score (KSS) assessed. A total of 621 primary TKRs were analyzed with an average follow-up of 11.25 years (9.15-14.55). The mean age was 69.53 years. The mean KSS was 88.97 and mean flexion increased from 88.3 to 103.5 degrees at 10 years. Kaplan-Meier's analysis revealed a survivorship of 96.5% with revision for any reason as the end point and 98.9% if aseptic loosening was the reason for revision at 14 years. This study revealed excellent mid- to long-term results with the NexGen LPS prosthesis.

The aim of the study is to evaluate the efficacy of a nurse-led interdisciplinary programme based on healthy eating, physical exercise, and cognitive behavioural therapy applied to anthropometric and ...
The recent technological evolution has also allowed for the treatment of juxtarenal abdominal aortic aneurysms (JAA) with an endovascular technique but short and long-term results must be compared wit...
Chronic hypertension is a multifactorial disease that is highly associated with cardiovascular disorders. Physical activity, such as long-term exercise, is advocated as a treatment for hypertension, b...
The purpose of this trial is to study potential differences between two prostheses, including: "feel of prosthesis" (i.e., how natural does the prosthesis feel), range of motion (ROM), pai...
Numerous studies have echoed the superior clinical outcomes of posterior-stabilized (PS) total knee arthroplasty compared to posterior cruciate-retaining (CR) total knee arthroplasty. The ...
The purpose of this study is to determine if there are any clinical or radiographic differences in non-posterior stabilized rotating mobile bearing design versus a posterior stabilized rot...
MicroPort Orthopedics (MPO) is conducting this study to build upon the results of a previous study which showed the Medial Pivot (MP) system required lower quadriceps activation than subje...
SUMMARY A prospective, randomized, single-blinded clinical trial is proposed to compare three tibial tray designs for patients undergoing total knee arthroplasty. This study is designed to...

Persons who have experienced prolonged survival of HIV infection. This includes the full spectrum of untreated, HIV-infected long-term asymptomatics to those with AIDS who have survived due to successful treatment.
A persistent increase in synaptic efficacy, usually induced by appropriate activation of the same synapses. The phenomenological properties of long-term potentiation suggest that it may be a cellular mechanism of learning and memory.
A persistent activity-dependent decrease in synaptic efficacy between NEURONS. It typically occurs following repeated low-frequency afferent stimulation, but it can be induced by other methods. Long-term depression appears to play a role in MEMORY.

A joint is where two or more bones come together, like the knee, hip, elbow, or shoulder. Joints can be damaged by many types of injuries or diseases, including Arthritis - inflammation of a joint causes pain, stiffness, and swelling with ...
Arthroplasty is a surgical procedure to restore the integrity and function of a joint. A joint can be restored by resurfacing the bones. An artificial joint (called a prosthesis) may also be used. Various types of arthritis may affect the joints. Osteo...
