This document outlines the structure and scoring of a mock clinical examination for a case involving congenital knee deformities (CKD). The exam consists of 4 phases: history taking, clinical examination, presentation of findings, and management plan. For the CKD case, the candidate is expected to examine the knees and hips, identify specific deformities, and know associated conditions. Radiographs would reveal pathoanatomic findings like quadriceps contracture. The candidate must justify non-operative or operative treatment, and for surgery, describe a V-Y plasty procedure and post-operative casting position. References and guidelines are provided.

2. 4 short case
System
 10 Minutes on each case
 1 minutes un-observed delay in
between to switch over candidates
– 5 minutes for clinical examination
– 5 Minutes for Viva
– One examiner ask Q & other to
observe OR other examiner may ask
Q to clarify statement given by
Examinee
 Examiner gives command for what
to examine and give brief history
 Examinee can ask 1-2 relevant
questions about patient condition,
investigation or response to therapy.
 Examiner may respond verbally or
furnishes results if asked for.
 Examinee may narrate findings
• Answers are scored phase-wise on a
key.

2. How will you proceed
further?
If the candidate reads X-Ray
correctly, draw referral lines and
request additional imaging show him
and examiner may ask why & what?
