Summary
The Scandinavian Total Ankle Replacement (STAR) demonstrated 73% implant survival at 15 years for end-stage ankle arthritis. Patients experienced significant pain relief and maintained function, though additional procedures were common.
Area of Science:
- Orthopedic surgery
- Biomedical engineering
- Arthroplasty research
Background:
- Total ankle arthroplasty (TAA) is a primary treatment for end-stage ankle arthritis.
- The Scandinavian Total Ankle Replacement (STAR) is the sole 3-piece mobile bearing prosthesis in the US.
- This study evaluates long-term outcomes of the STAR prosthesis.
Purpose of the Study:
- To report 15-year implant survivorship for the STAR prosthesis.
- To assess patient outcomes, including function and pain, in a cohort of STAR ankle replacements.
- To document radiographic changes and complications associated with the STAR prosthesis over 15 years.
Main Methods:
- Retrospective analysis of 84 STAR total ankle arthroplasties performed between 1998-2000.
- Kaplan-Meier survival analysis for metal component survivorship at 15 years.
- Clinical evaluation of 24 available patients, including radiographic assessment, complication recording, and AOFAS scores.
Main Results:
- 15-year metal implant survival rate was 73%.
- 70.7% of evaluated patients maintained prosthetic alignment; 1 patient required subtalar fusion.
- AOFAS scores improved significantly from 39.6 to 71.6; 52.4% required subsequent procedures.
Conclusions:
- STAR ankle implants retained at 9 years showed high likelihood of 15-year survival.
- Patients experienced sustained pain relief and minimal functional decline.
- While effective, supplementary procedures are common in long-term TAA management.

01:10Ankle Joint
3.1K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

01:16Other Nuclides: 31P, 19F, 15N NMR

Many organic, inorganic, and biological molecules contain spin-half nuclei such as nitrogen-15, fluorine-19, and phosphorus-31. As a result, NMR studies of these nuclei have found extensive applications in chemical and biological research.
While fluorine-19 and phosphorous-31 have high natural abundances (100%) and positive gyromagnetic ratios, nitrogen-15 has a low natural abundance and a negative gyromagnetic ratio. However, nitrogen-15 is still preferred over nitrogen-14 (which has a...

01:30Continuous Renal Replacement Therapy
1.2K
Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

01:12Total Voids in Concrete
515
Total voids in concrete encompass gel water volume, capillary pores, and entrapped air. Gel water (retained within the cement hydration products) and physically entrapped or adsorbed water are significant for the hydration process. For complete hydration, it's estimated that the space needed for the products of a cubic centimeter of cement doubles. Capillary pores constitute the unoccupied space within the hydrated cement paste, with their size largely influenced by the water-to-cement...

01:05Total Internal Reflection Fluorescence Microscopy
13.5K
Total internal reflection fluorescence microscopy or TIRF is an advanced microscopic technique used to visualize fluorophores in samples close to a solid surface with a higher refractive index, such as a glass coverslip. TIRF only allows fluorophores in proximity to the solid surface to be excited. When light from a medium with a lower refractive index (such as air) hits the glass coverslip at a critical angle, the light undergoes total internal reflection stead of passing through the glass.

01:26Extracorporeal Removal of Drugs: Continuous Renal Replacement Therapy
237
Continuous Renal Replacement Therapy (CRRT) is an essential intervention for patients experiencing severe kidney dysfunction. This therapy offers a continuous mechanism for removing fluids and toxins from the bloodstream, leveraging the patient’s blood pressure to facilitate filtration through a specialized filter. This method contrasts with intermittent dialysis, providing a gentler and more consistent removal of waste products and excess fluid, which is particularly beneficial in...
