Despite improved surgical care, one year mortality remains 14-30%, and fewer than half of the survivors regain their pre-fracture functional status. After a hip fracture, patients are primarily concerned with what they will be able to do in daily life. Wihout accurate predictions of mobility and Activities of Daily Life (ADL) independence, it is difficult to set realistic expectations and make appropriate decisions regarding treatment and rehabilitation. While there have been advancements in developing predictive models for mortality following hip fractures, there is a notable gap in models focused on predicting functional recovery. This study aims to develop and validate a machine learning-based model that can predict mobility and ADL independence three months after obtaining a hip fracture.",[25],"Hip Fractures (ICD-10 72.01-72.2)","RECRUITING","2026-06-02",{"date":29,"type":30},"2026-06-04","ACTUAL",{"date":32,"type":30},"2016-01-01",{"date":34,"type":21},"2027-12-31",{"name":36,"class":37},"JointResearch","OTHER",1,{"id":40,"slug":41,"hasResults":11,"nctId":42,"briefTitle":43,"officialTitle":44,"acronym":45,"eligibilityCriteria":46,"healthyVolunteers":11,"sex":17,"minAge":47,"maxAge":4,"enrollmentInfo":48,"targetDuration":4,"studyType":50,"phases":51,"briefSummary":53,"conditions":54,"keywords":57,"overallStatus":26,"whyStopped":4,"lastUpdateSubmitDate":63,"lastUpdatePostDateStruct":64,"startDateStruct":66,"completionDateStruct":68,"leadSponsor":70,"locationsCount":71},"100590771","haka-routine-follow-up-at-1-year-after-hip--or-knee-arthroplasty-wasting-resources-or-appropriate-healthcare-100590771","NCT06971757","HAKA: Routine Follow-Up at 1 Year After Hip- or Knee Arthroplasty: Wasting Resources or Appropriate Healthcare?","Cost-effectiveness of Routine Follow-up at One Year After Total Hip and Knee Arthroplasty Compared to Check-up on Demand: a Multicenter Hybrid Stepped-wedge Cluster De-implementation Study","HAKA 1year FU","Inclusion Criteria:\n\n* Painful and disabled hip or knee joint resulting from osteoarthritis\n* Scheduled for primary THA or TKA surgery\n* Age 50 years or older at the time of THA or TKA\n* Capable and willing to complete questionnaires\n* Proficient in Dutch or English\n* Willing to provide informed consent\n\nExclusion Criteria:\n\n* Other indication for surgery than osteoarthritis\n* Scheduled for hip or knee revision arthroplasty, except a conversion from unicompartmental knee arthroplasty to TKA or from hip hemiarthroplasty\u002Fresurfacing to THA\n* Already participating in this study due to a previous hip or knee surgery","50 Years",{"count":49,"type":21},1000,"INTERVENTIONAL",[52],"NA","After undergoing total hip or total knee arthroplasty, current guidelines recommend routine follow-up with an X-ray within 3 months and again at 1 year. Follow-up at 5 years (for hip arthroplasties) or every 5 years (for knee arthroplasties) is also considered worthwhile according to the guideline. However, these follow-up appointments require considerable time from patients, caregivers, and healthcare professionals, and it is unclear whether they are truly beneficial. It is possible that a single follow-up within 3 months is sufficient. This could potentially prevent over 100,000 unnecessary hospital visits per year, resulting in significant cost savings. If patients or healthcare providers have concerns, they can always request an additional follow-up.\n\nThe HAKA trial consists of three different work packages (WPs). This trial (WP1) investigates the 1-year follow-up, WP2 examines the 10-year follow-up, and WP3 is a qualitative study exploring the experiences and perceptions of patients and healthcare professionals. The aim of the HAKA trial is to safely reduce routine follow-up appointments after total hip or knee arthroplasty and to revise current clinical guidelines accordingly.",[55,56],"Hip Arthroplasty, Total","Knee Arthroplasty, Total",[58,59,60,61,62],"total hip arthroplasty","total knee arthroplasty","follow-up","PROMIS physical function","healthcare consumption","2025-11-14",{"date":65,"type":30},"2025-11-18",{"date":67,"type":30},"2025-07-01",{"date":69,"type":21},"2029-12-31",{"name":36,"class":37},9,{"id":73,"slug":74,"hasResults":11,"nctId":75,"briefTitle":76,"officialTitle":77,"acronym":78,"eligibilityCriteria":79,"healthyVolunteers":11,"sex":17,"minAge":4,"maxAge":4,"enrollmentInfo":80,"targetDuration":4,"studyType":22,"phases":4,"briefSummary":82,"conditions":83,"keywords":4,"overallStatus":26,"whyStopped":4,"lastUpdateSubmitDate":85,"lastUpdatePostDateStruct":86,"startDateStruct":88,"completionDateStruct":90,"leadSponsor":92,"locationsCount":38},"100582560","the-10-year-follow-up-of-the-delta-tt-trial-100582560","NCT06864897","The 10-year Follow-up of the Delta-TT Trial.","The 10-year Follow-up of the Delta-TT Trial: Stability of the Delta-TT Cup with Polyethylene Insert Compared to the Delta-TT Cup with Ceramic Insert.","RSA-10","Inclusion Criteria:\n\n* Enrolled in the initial Delta-TT trial\n\nExclusion Criteria:\n\n* Patient is unable or unwilling to sign the Informed Consent specific to this study.\n* Patient is unsuitable for participation in the study based on the investigator's judgement.",{"count":81,"type":21},51,"This 10-year follow-up study aims to further investigate long-term migration patterns of the uncemented Delta-TT cup and H-MAX S stem, comparing outcomes between ceramic and polyethylene liners.
