Arm && Interventions

Group	Intervention	Description

Cemented TKA	Triathlon	Cemented TKA (Triathlon, Stryker) include patellar resurfacing

Primary Outcome Measures

Name	Time	Method
Compare mean Forgotten joint score between 2 groups	at 1 year	The total score ranges from 0-100, where a high score is the best outcome

Secondary Outcome Measures

Name	Time	Method
Radiological finding	post-op 2, 6 week, 3, 6, 12 month	Radiolucent line at femoral, tibial and patellar components which measured from radiolucent intervals (measured in millimetres) between the cement or prostheses and the bone according to the knee society total knee arthroplasty roentgenographic evaluation and scoring system
Pain level	Once daily 1-14 days after surgery then once a week until 3 months	VAS for pain (0-100)
Operative time	intra-operative assessment
modified the Western Ontario and McMaster Universities Osteoarthritis Index score	post-op 2, 6 week, 3, 6, 12 month	The total score ranges from 0-96, where a high score is the worse outcome
complication	until 1 year after surgery	such as fracture, infection, stiffness
Range of knee motion	post-op 2, 6 week, 3, 6, 12 month	flexion and extension (degrees) which measured by long goniometer
