Silkeborg Knee Replacement Cohort Study

Disease specific Patient Reported Outcome Measure regarding function and pain. Each question is answered by ticking a box on a five-point Likert scale. Responses are then totalled to obtain a score between 0 and 48, with 48 being the best.

A generic Patient Reported Outcome Measure. The General Self-efficacy Scale measures self-efficacy, defined as an individual's belief in his or her capacity to execute behaviors necessary to produce specific performance attainments.Each question is answered by ticking a box on a four-point Likert scale. Responses are then totalled to obtain a score between 10 and 40, with 40 being the best. he General Self-efficacy Scale measures self-efficacy, defined as an individual's belief in his or her capacity to execute behaviors necessary to produce specific performance attainments.Each question is answered by ticking a box on a four-point Likert scale. Responses are then totalled to obtain a score between 10 and 40, with 40 being the best. The General Self-efficacy Scale is included in the data collection from January 2019 til March 2019, which corresponds to about 550 patient responds.

Patient Reported Outcome Measure, that measures how patients experience pain. Pain catastrophizing is characterized by the tendency to magnify the threat value of a pain stimulus and to feel helpless in the presence of pain, as well as by a relative inability to prevent or inhibit pain-related thoughts in anticipation of, during, or following a painful event such as surgery for example. Each of the 13 questions is answered by ticking a box on a 5 point Likert Scale from 0 (not at all) to 4 (all the time). A total score is yielded (ranging from 0-52 and 0 being the best), along with three subscale scores assessing rumination, magnification and helplessness. The PCS is included in the data collection from March 2019 til end of the cohort study, which corresponds to about 950 patient responses (instead of The General Self-efficacy Scale)

GPE measures patients' perception of the change in their knee problems after the surgery. GPE will be assessed with the anchor question "Overall, how are the problems now (pain and ability to perform daily activities) in the knee on which you had surgery, compared to prior to your operation?" Patients respond on a 7-point scale ranging from "better, an important improvement" to "worse, an important deterioration".

Satisfaction is measured with the question "Overall, how satisfied are you with the sugery?". Patients respond on a 5 point scale ranging from "very satisfied" to "very unsatisfied"

PASS measures satisfaction with the current knee function and will be assessed with the anchor question ""When you think of your knee function, will you consider your current condition as satisfying? With knee function, you should take into account your activities of daily living, your level of pain and other symptoms". Patients respond "yes" or "no". If patients respond "no" they are asked if the consider the treatment of ther knee problem as a failure.

Assessed with the anchor question "knowing what your knee arthroplasty surgery did for you, if you could go back in time, would you still have undergone this surgery?" Patients respond "yes", "no" or "uncertain".

Measured as length of stay and reason for not being discharged on post operative day 0 (same-day) will be provided.

• number of patient-initiated phone calls
• number of unscheduled visits in the outpatient clinic
• number of inpatient readmission (admission to hospital ward taking up a bed)

The reason for readmission (=complication) in relation to:

• patient-initiated phone calls
• unscheduled visits in the outpatient clinic
• inpatient readmission (admission to hospital ward taking up a bed) will be reported.
