Preoperative planning is an important step in the actual delivery of joint replacement as it allows the patient to go through a comprehensive assessment and preparation for undertaking joint replacement in a schematic fashion. This begins with a thorough clinical assessment by their operating surgeon and a series of investigations followed by actual planning of their hip joint replacement, utilizing template on their standardized radiographs. Templating process allows assessment of their anatomical landmarks to mark as reference points while implanting prosthesis with correct depth. This will allow the surgeons to restore hip biomechanics and thereby improving post-surgical outcomes. This will further allow anticipating

Some surgeons do not like to proceed with this important step of templating prior to their joint replacement surgeries. However, unless it is done systematically, it might be difficult, even for the experience hip surgeons to identify those hips, which will definitely benefit from a proper anatomical and mechanical assessment. Moreover, these less planed cases without templating are at increase risk to suffer inadequate hip biomechanics and higher complication rates including trendelenburg gait, joint dislocation, significant leg length discrepancy, peri prosthetic fracture and trochanteric pain. It has been proven to have similar efficacy of preoperative templating by the junior surgeons in training as their senior counter parts [11]. Thus it makes it a legitimate cause for carrying out this vital process of templating of the hip joint prior to actual implantation of the prosthesis. In crux this will improve the long-term outcome

**Classifications Used in Total Hip Arthroplasty**

Total hip arthroplasty is one of the most successful operation to be done and is definitely a rewarding procedure for both the surgeon and the patient. Ever since 3 days of low friction arthroplasty by Sir John Charnley, there has been considerable interest in improvement in the knowledge of surgical techniques and hip biomechanics. Over the past two decades there has been an exponential increase in total hip replacements. Therefore strategies to simplify the procedure and classifications to encounter difficulties in treatment plans were devised. It is imperative for consultants and trainees to be aware of these classifications systems which are helpful in pre op, intra op and postop planning.
