Cementless Versus Cemented Tibial Fixation in Posterior Stabilised Total Knee Replacement - a Randomised Trial

Conditions

None listed

Brief summary

This randomised study compared how tibial fixation affected component migration, bone remodelling and clinical outcomes in Posterior Stabilised Total Knee Replacements. 100 patients were randomised to receive TKRs with cemented or cementless tibial components. The hypothesis was that tibial fixation method would impact implant stability.

Interventions

Participants underwent Total Knee Replacement surgery, with all variables standardised except tibial component fixation, where one group was cemented and one cementless. Procedure duration was about 60 minutes of surgical time per case. The implants were monitored for migration, bone mineral density and subjective clinical scores including Oxford Knee Score, Short From 12 and pain scores. Physical materials used include Advanced Coated System Total Knee Replacement implants in cemented and ceme

Procedure duration was about 60 minutes of surgical time per case. The implants were monitored for migration, bone mineral density and subjective clinical scores including Oxford Knee Score, Short From 12 and pain scores. Physical materials used include Advanced Coated System Total Knee Replacement implants in cemented and cementless tibial models. Two experienced arthroplasty surgeons carried out the operations, all were done at Hollywood Private Hospital. Followup was conducted at 3, 12 and 24 months post surgery
