Summary
Unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA) yield similar patient-reported outcomes for knee osteoarthritis. Surgeons can consider other factors when choosing between UKA and TKA for comparable results.
Area of Science:
- Orthopedic Surgery
- Biomedical Engineering
Background:
- Unicompartmental knee arthroplasty (UKA) is an option for knee osteoarthritis (OA).
- Some surgeons prefer total knee arthroplasty (TKA) even for UKA candidates.
- The choice between UKA and TKA can be complex.
Purpose of the Study:
- To compare patient-reported outcome (PRO) scores for UKA versus contralateral TKA.
- To evaluate pre-operative and post-operative PROs in patients receiving both procedures.
Main Methods:
- 17 patients underwent UKA and contralateral TKA between 2003 and 2014.
- Validated PROs (SF12, KSS, WOMAC) were used for pre- and post-operative assessment.
- Student's paired t-tests compared PRO scores between UKA and TKA.
Main Results:
- Mean follow-up was 2.5 years.
- No significant pre-operative PRO differences were found between UKA and TKA.
- No significant post-operative PRO differences were observed between UKA and TKA.
Conclusions:
- UKA and TKA demonstrate comparable patient-reported outcomes at mid-term follow-up.
- Surgeons can expect similar PROs regardless of choosing UKA or TKA.
- Other factors can guide the surgical decision when PROs are similar.

01:23Knee Joint
3.2K
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
487
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...

01:06Natural Selection and Mating Preferences
542
The principle of natural selection posits that organisms better adapted to their environment are more likely to survive and reproduce. This principle is closely intertwined with mating preferences, a key aspect of sexual selection, which evolutionary psychologists believe is driven by instincts to propagate one's genes. Such instincts significantly influence mating behaviors and preferences between genders.

01:05Total Internal Reflection Fluorescence Microscopy
13.4K
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.

01:13Patient-centered Care
3.0K
Patient-centered care involves delivering care beyond inpatient hospitalization. Reflective practice can enhance a patient-centered approach. Reflective practice is a process of reasoning that considers all aspects of the present situation, including practicalities, learning from personal practice, and consideration of patient needs. Patients appreciate care decisions made while considering their input. Involving the patient in their care provides the patient with a sense of contribution rather...
