Total elbow replacement is a necessary treatment for (i) trauma patients and (ii)
rheumatoid arthritis. Due to this disease, the cartilage of the elbow joint wears down,
and the movement of the joint is very painful and can affect daily life for the patient.
Analgesics are the temporary solution for this condition. However, considering the
severity of the disease a doctor can suggest total elbow arthroplasty (TEA). In which
the normal joint is replaced with a metal joint to facilitate painless elbow joint motion.
Currently, implants in the market are developed by foreign companies, these implants
were developed considering western population.
