"The most cost-effective and commonest method of follow-up. Baseline radiographs should be obtained immediately post-operation."
"pain: up to 20% of patients have more pain/swelling than pre-replacement 11"

"True axial imaging allows assessing for rotational alignment of the femoral component. To this end, two lines are drawn, which should be parallel:"

"patellar component: high-density polythene; may be metal-backed"
"unconstrained prostheses: most widely used; the patient's supporting soft tissues help maintain stability"
"semi-constrained implants: more stable, decreased range of motion; closely conforming tibial and femoral components"
"constrained implants: hinged mechanism; most stable, but most limited range of motion, meaning more mechanical stress and susceptibility to wear, fatigue, and loosening; usually used in:"

"retained; this is usually the case with unconstrained prostheses"
"polythene (radiolucent) spacer in tibiofemoral joint space: equal width medially and laterally; NB: beam angle, patient positioning or post-op flexion contracture may distort this"
"There are many designs in use, but broadly speaking, TKA is characterised by the degree of constraint, polythene spacer fixation, and posterior cruciate ligament (PCL) retention or removal."
