Kort klinisk retningslinje vedr. Patella komponent i primær total knæ alloplastik

Background:The usage of patella resurfacing in total knee replacement (TKA) is optional and the two methods are considered equals. In Denmark in 2020 71.8 % of total knee replacement was made with patella resurfacing. The high percentage of resurfacing reflects the assumption that the revision rate due to anterior knee pain is higher with the patella not resurfaced. DSHK (Danish society of hip and knee arthroplasty) therefore decided to assess the literature and make recommendations in a short clinical guideline (KKR).Aim:To investigate if patella resurfacing in primary TKA has better results concerning short and long term follow up revision rate, patient reported outcome and pain score, than non-resurfaced primary TKA. Materials and methods:Two meta-analysis was found, publiced in 2021 and 2023. Both included the same 30 RCT studys and no further RCT studys has been publiced since. AMSTAR II critical appraisal toolwas used to assess the quality of the meta-analysis. GRADE assessment was used to evaluate the strength of evidence for the relevant outcomes. Interpretation/Conclusion:This KKR is a weak recommendation towards using patella resurfacing in TKA due to a significant lower revision rate after 5 years follow up.
