Summary
Revision total knee arthroplasty (TKA) for arthrofibrosis improves range of motion and function. However, high complication and reoperation rates necessitate caution in this patient group.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
- Reconstructive Surgery
Background:
- Arthrofibrosis following total knee arthroplasty (TKA) is a primary driver of patient dissatisfaction.
- Limited evidence exists regarding the efficacy of revision arthroplasty for TKA-related arthrofibrosis.
Purpose of the Study:
- To evaluate the outcomes of revision TKA specifically for arthrofibrosis.
Main Methods:
- Retrospective review of 46 revision TKAs for arthrofibrosis (2007-2015).
- Minimum 2-year follow-up assessing range of motion (ROM), complication rates, and Knee Society Scores (KSS).
Main Results:
- Significant improvements observed in ROM (flexion: 88° to 103°, extension: 11° to 3°, P < .001) and KSS.
- No correlation found between patient/surgical factors and outcomes.
- Complication rate was 28.2% with a 17.4% reoperation rate.
Conclusions:
- Revision TKA for arthrofibrosis can enhance ROM and KSS.
- High rates of revision, reoperation, and complications warrant careful consideration.
- Approximately 30% of patients experienced decreased KSS components or ROM post-revision.

01:23Knee Joint
3.3K
The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris...

01:12Total Voids in Concrete
499
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.

1.3K
Attenuated total reflectance (ATR) infrared spectroscopy is a powerful analytical technique used to study the composition of materials. It is widely employed in chemistry, materials science, forensic science, and other fields where sample characterization is required. ATR has several advantages over traditional transmission IR spectroscopy, including the requirement of little to no sample preparation and the ability to analyze a wide range of samples.
