'tear process'

Arthroscopic Surgeryis done with the help of miniaturized telescope to visualize the interior of the joint (Arthroscope). Special miniaturized instruments are used to perform the operation. These include manual instruments, motorized cutters (shaver system), electrocautery, radio-frequency ablation devices, etc. A large number of procedure-specific instruments and ancillary equipment is used. Arthroscopic surgeons typically undergo years of training to acquire and hone their surgical skills.

In a total hip replacement, the worn out surfaces are replaced by artificial device (prosthesis). The socket is replaced by a hemispherical cup which has a metallic shell and an inner high-density polyethylene liner. The head is replaced by a metal sphere supported on a tapered stem which fits into the bony canal of the femur. The implants have specially textured surface which allows them to grip the bone. Sometimes acrylic bone cement is also used to fix the implants.
