Summary
Chronic pain affects 20% of total knee arthroplasty (TKA) patients, impacting quality of life. Understanding risk factors and multifactorial causes is key for effective TKA pain management.
Area of Science:
- Orthopedics
- Pain Medicine
- Rehabilitation
Background:
- Approximately 20% of patients experience chronic pain post-total knee arthroplasty (TKA).
- This chronic pain significantly impacts health-related quality of life, leading to functional limitations, distress, depression, and social isolation.
- Past pain assessment methods have been inadequate, necessitating multidimensional approaches.
Purpose of the Study:
- To highlight the need for in-depth, multidimensional assessment of chronic pain after TKA.
- To review known and potential risk factors for developing chronic pain post-TKA.
- To discuss the multifactorial etiology and challenging treatment landscape of TKA-related chronic pain.
Main Methods:
- Review of existing literature on chronic pain after TKA.
- Identification and categorization of risk factors (preoperative, intraoperative, postoperative).
- Discussion of current understanding of pain etiology and treatment strategies.
Main Results:
- Chronic pain after TKA is a significant issue affecting a substantial patient subset.
- Risk factors are diverse, encompassing biological, surgical, and psychosocial elements.
- The multifactorial nature of TKA pain necessitates tailored and multidisciplinary treatment approaches.
Conclusions:
- Improved, validated patient-reported outcome measures are crucial for accurate pain assessment.
- Further research into preoperative interventions and the multifactorial causes of TKA pain is needed.
- Evaluating the effectiveness of individualized, multidisciplinary treatments is essential for optimal patient care.

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...

01:20Pain
1.4K
Pain serves as a critical warning signal that alerts the body to potential or actual harm. When mechanical pressure on the skin is intense, such as from a sharp pinch, the sensation transitions from touch to pain. Similarly, extreme temperatures, like a hot pot handle, convert the sensation of heat into pain. Pain can also result from overstimulation of other senses, such as blinding light, loud noise, or the intense heat from habañero peppers. This ability to sense pain is essential for...

01:12Total Voids in Concrete
492
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...

01:25Analgesia and Pain Management
1.7K
Pain is critical to various clinical pathologies, provoking an urgent need for effective management. Pain, whether acute or chronic, is a complex neurochemical process. Its alleviation depends on the type, with nonopioid analgesics effective for mild to moderate pain, such as musculoskeletal or inflammatory pain, while neuropathic pain responds best to anticonvulsants, tricyclic antidepressants, or serotonin/norepinephrine reuptake inhibitors. For severe acute or chronic pain, opioids may be...

01:23Chronic Pharyngitis
12.0K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

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.
