Patients with severe Varus knees is not uncommon in developing countries, and TKA offers good results. The type of release required and need for constrained prosthesis needs to be defined. Purposes-1) Assess the adequacy of sequential medial soft tissue release in correcting the varus deformity in severe primary varus knees. 2) Assess the need for using constrained type of components. Patients and methods-75 primary severe varus knees (≥20 degrees) in 52 patients presenting to us over 3 years

Group A (20-25 degree) had 31 patients, Group B (26-30 degrees) had 31 patients, Group C (31-35 degree) had 8 patients and Group D (36-40 degree) had 5 patients. All patients were evaluated for the type of release required, the type of defect reconstruction needed and the need for constrained prosthesis intraoperatively. KSS scores were documented preoperatively and at final follow up.
