Arthroplasty is Joint Replacement

More About Arthroplasty & Techniques Employed

When skeletal components are surgically repaired or replaced with the addition of implants in place of those completely degenerated the procedure is known as arthroplasty. Arthroplasty comprises of many techniques.

In the case of unicompartmental arthroplasty, most of the natural tissue which has escaped degeneration is left alone and only the degenerated or damaged portion is removed. In the case of TKR or total knee replacement scrapping of healthy tissues has to be avoided as well, and in both cases, technology comes into the picture. Good quality implants play a major role in the post-operative outcomes besides the employment of mapping techniques. By the year 2050, there will be over 130 million sufferers seeking some form of joint procedures all over the World. India (APAC) the Arab World and Australia are among the high-demand region with the number of cases rising exponentially.

Robotic Assistance

In the latest development, robotic-assisted technology makes the whole procedure accurate and results in less scraping of healthy tissues. The robotic-assisted technologies are being used in all fields and their inclusion in joint-related surgery is no surprise.

The technique employs computer navigation assistance and instrumentation. The method behind the technique is to accurately map the damage and then use precision instruments to scrap damaged or degenerated tissue. The accuracy employed is greater using robots but the surgeon is not replaced by all means. Another benefit that accrues from this technology is accurately mapping the implant position for much better functionality. For any hospital or clinic, it is imperative to train experienced orthopedics in this method for better medical outcomes. The limits of this technology are high installation and operative costs. The rise of this technology has been gradual but more than 38 % of surgeons are using this technology. Some of the popular robotic systems used in arthroplasty are

Human Knee

The applications and outcomes of the robotic systems mentioned above may differ. About 4.5 % of patients underwent TKR using robotic assistance technology between 2005 to 2014 in the USA.
Patient-Specific Instrumentation

PSI is an alternative to expensive robotics and in this technique, 3D imaging techniques such as MRI and CT scan are used. This is a highly patient-specific approach and an image map of the patient structure is created. The instrumentation is then designed by commercial engineers which deliver absolute accuracy during the procedures. This helps in accurately planting implants with the structure of the joints.


The joint anomalies are rising fast and newer technologies though extremely helpful are bridled with high installation and operation costs. Nevertheless, the techniques and technologies are vastly employed by hospitals and clinics in developed countries and in countries with high patient turnover as in India.
