Eligibility

Inclusion criteria

Inclusion criteria: a) Patients diagnosed with bilateral knee osteoarthritis with varus deformity . b) patients aged between 50 and 80 years and also medically fit for bilateral TKR . c) patient with ROM difference between bilateral knee not more than 10 degree and varus deformity difference less than 5 degree. d) Patients willing to undergo one knee conventional and other knee robotic TKR after understanding all the possible complications and gives audiovisual consent for the procedure.

Exclusion criteria

Exclusion criteria: a) Patients with inflammatory arthritis (e.g., rheumatoid arthritis). b) Patients with a history of knee infections or previous knee surgeries. c) patient with neuromuscular disorders affecting lower limb function . d) Patients with fixed deformities of the knee joint e) Patients with any contraindications for surgery like severe cardiac ,renal ,pulmonary and any other severe systemic illness.

Design outcomes

Primary

Measure	Time frame
To evaluate and compare functional outcomes by using standardised scoring systems- WOMAC ,OKS , VAS at defined postoperative intervals . To assess radiological outcomes such as implant positioning and alignment between robotic and conventional TKR using HKA angle, femoral coronal component angle (FFC),tibial coronal component angle (FTC),posterior tibial slope angle (PSA). Timepoint: 6 months	—

Secondary

Measure	Time frame
To compare operative parameters such as duration of surgery , intra operative blood loss and need for soft tissue releases between robotic and conventional TKRTimepoint: on the day of surgery	—
