Silkeborg Knee Replacement Cohort Study
研究概览
详细说明
All patients follow the same fast-track program including same day surgery for elective knee replacement surgery at the Silkeborg Regional Hospital in Denmark, which includes detailed preoperative written information, multidisciplinary education course for patients and relatives, optimized multimodal pain treatment and early postoperative rehabilitation. Before the admission for surgery, patients will be asked to fulfill several questionnaires and baseline information regarding work situation, educational level and previous treatments. At two weeks there, there is a scheduled follow up by a physical therapist and a nurse at the hospital. At three months there is a scheduled follow up by telephone with a physical therapist.
The study will adhere methodologically to the STROBE guidelines and checklist for prospective cohort studies (www.strobe-statement.org).
Further description is provided elsewhere as eligibility criteria and outcome measures.
Addition to the description:
In January 2019 we started collecting 1 year follow-up data and included questions regarding treatment success, satisfaction and willingness to repeat the surgery.
In March 2019 we decided to make a change in the baseline collection of relevant predictors for primary outcome. The reason for the change was to be able to answer more relevant scientific questions in the cohort study. We replaced "The General Self-efficacy Scale" with "Pain Catastrophizing Scale" and excluded "The General Self-efficacy Scale" from the 12 weeks follow-up collection of outcome measures.
March 2020:
The SIKS study was planned to continue recruitment until reaching minimum 1,000 TKA patients with follow-up data which was deemed sufficient for the purpose of the planned studies. In March 2020, the COVID-19 pandemic closed down all elective orthopaedic surgeries. Because of that, we decided to stop the recruitment to the cohort study with the last patient included (at March 16th, 2020, prior to the COVID-19 lockdown).
December 2020:
The first substudies are planned using data from the SIKS cohort:
Predictors of knee pain and functional outcome following Total Knee Arthroplasty - a prospective cohort study with 12 months follow up
Primary outcome:
Oxford Knee Score at 12 months
Is it feasible and safe to discharge patients on the day of surgery after a total knee arthroplasty?
Primary outcomes Feasibility measured as length of stay Safety measures as readmission (phone calls, outpatient visits and inpatient visits) and the related reason
Secondary outcomes Oxfort knee score (90 days) Pain intensity (90 days)
- Associations between preoperative BMI and postoperative physical activity level and functional capacity 12 months after UKA or TKA surgery.
Primary outcome UCLA scale (12 months)
Secondary outcomes Oxford Knee Score (12 months)

The General Self-efficacy Scale (continous)
大体时间：Pre surgery
|
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.

The General Self-efficacy Scale is included in the data collection from January 2019 til March 2019, which corresponds to about 550 patient responds.

Pain Catastrophizing Scale (PCS)
大体时间：Pre surgery
|
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)

Global Perceived Effect (GPE)
大体时间：52 weeks after surgery
|
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 with the surgery

Patient Acceptable Symptom State (PASS)
大体时间：52 weeks after surgery

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.
