Conditions
Interventions
RSA acquisitions during 6 different positions of the operated knee to assess the induced migration
Sponsors
LUMC is the sponsor of the study
Eligibility
Inclusion criteria
Inclusion criteria: Patients will be included if • they underwent TKR for primary as well as secondary gonarthrosis as long as the indication for surgery is clearly specified • a minimal set of patient characteristics (age, gender, BMI, co-morbidity) and disease characteristics (radiological severity, knee function and alignment, status of other knee or hip joints, previous surgeries of the affected knee) is available. • they are at least `up to date' in terms of follow-up of their respective study (i.e. the most recent examination was less than a year ago and patients have apost-operative examination) • they participated for at least three years in their respective study and have a usable MTPM-value (i.e. >_ 3 bonemarkers can be consistently matched with the reference-examination with a CN < 120 over the most recent iwo years of fol low-u p • their standard RSA data meets the criteria as mentioned in the ISO-standard • they are willing to participate and able to perform the 4 pre-set tasks for the inducible displacement
Exclusion criteria
Exclusion criteria: Patients will be excluded from participation if they do not meet the inclusion criteria, or if they already underwent revision surgery of their TKR since the start of the study they were enrolled in.
