Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Osteoarthritis Outcome Score | 12 weeks after surgery | The Patient self-assessed Injury and Osteoarthritis Outcome Scores for Knee (KOOS) and hip (HOOS) are joint-specific instruments: The KOOS evaluates both short-term and long-term consequences of knee injury. It holds 42 items in 5 separately scored subscales; Pain, other Symptoms, Function in daily living (ADL), Function in Sport and Recreation (Sport/Rec), and knee-related Quality of Life (QOL). The HOOS evaluates both short-term and long-term consequences of hip injury. It holds 5 separate patient-relevant dimensions: Pain (P), Symptoms (S), Activity limitations daily living (ADL), Function in sport and recreation (SP) and hip related quality of life (QOL). Both scores are percentage scores from 0 to 100, 0 representing extreme problems and 100 representing no problems. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Patient User Experience | at final follow-up approx. 7 months after surgery | A measurement just for the patients of the study group. The user feedback is collected at the endpoint |
| Patient compliance | at final follow-up approx. 7 months after surgery | A measurement just for the patients of the study group. Data collection (Counting) how often patients use BPMpathway before and after operation to determine compliance with specification of using BPMpathway three times per day every day through data analytics |
| Economical [time and costs] | 12 weeks after surgery | Comparing conventional rehabilitation methods and tele-rehabilitation under cost aspects enlarged by quality aspects such as acceptance and satisfaction degree of the patient |
| Course of Active Range of Motion | repeatedly from pre-op consultation until final follow-up approx. 7 months after surgery | Study Group: Measured with BPMpathway sensor and app 3 times per day for the entire duration and measures with manual goniometer during all clinical visits (in 5° steps) Control Group: Measured with manual goniometer during all clinical visits (in 5°steps) |
| Patient satisfaction | 12 weeks after surgery | Based on a single question patients are asked to grade their level of satisfaction with the methodology and rehabilitation procedure. Patients can choose between very dissatisfied, dissatisfied, satisfied or very satisfied. The grades may be summarized as satisfied vs. dissatisfied. |
| Fatigue | at pre-operative consultation, post-operative consultation (12 weeks) and 6 months after surgery | Study Group and Control Group: Measures with Fatigue Severity Scale. The Fatigue Severity Scale is a 9-item scale which measures the severity of fatigue and its effect on a person's activities and lifestyle in patients with a variety of disorders. It was originally devised for people with Multiple Sclerosis or systemic lupus erythematosus. The items are scored on a 7-point scale with 1=strongly disagree and 7=strongly agree; the minimum score is 9 and the maximum score is 63. The higher the score the greater the fatigue severity. |
| Radiographic Analysis | through study completion, an average of 7 months postoperatively | Unless limited by patient or equipment constraints, all follow-up imaging exams will be obtained. Imaging will be used to evaluate the implant status as well as device condition and potential presence of device-related Adverse Events including fracture, wear, loosening or radiolucencies. X-rays are taken according to the radiographic protocol of the hospital and the set routine |
| Number of (Serious) Adverse Events | through study completion, an average of 7 months postoperatively | During the course of the study, any upcoming intra- or postoperative (serious) adverse device events or effects related or not related to the product under investigation, will be documented in the dedicated Case Report Forms. The total number of AEs will be summarized and further evaluated by the sponsor and reported according to local legislation and necessity. Recorded complications will be categorized and analyzed in order to assess the safety of the investigational product |
| Development of Pain | repeatedly through study completion, an average of 7 months postoperatively. | Study Group: Pain measured within BPMpathway app 3 times per day for the entire duration by Wong Baker Pain Score until post-operative follow-up meeting and during all clinical visits Control Group: Pain measured with Wong Baker Pain Scale during all clinical visits The Wong-Baker proves to be an inexpensive, yet easy to use, pain scale. The scale consists of six faces that range from no pain at all to the worst pain imaginable. The emotional faces range from smiling to grimacing. |
