Orthopaedic surgeon Dr RN Singh addresses the seminar on joint replacement surgery at Anup Institute of Orthopaedics & Rehabilitation in Patna on Sunday. Singh, who is also the founder of the institute, said: 'There is still lack of awareness among people about joint replacement surgery. The body of a person becomes weak and the bones also start losing their strength with the increasing age. A person develops problems in walking when his joints become weak. This condition is known as arthritis. Joint replacement surgery is the best available solution for arthritis. Most of the people who have undergone joint replacement surgery have overcome such problems.' Dr Ashish Singh, a doctor at Anup Institute of Orthopaedics & Rehabilitation, said people should get their joint replacement surgery done only in hospitals where there is a good operating theatre and an expert team of doctors.
