Trail-running After Knee or Hip Arthroplasty

Study Overview
=================
Brief Summary
-----------------
The incidence of indications for hip and knee arthroplasty is constantly increasing due to an increase in arthrogenic risk factors and life expectancy. In younger patients, with a higher functional demand, resumption of physical activity and sport is a major objective after resumption of walking and pain management. The repercussions of returning to sports after arthroplasty have been widely studied in the literature. Few studies have looked specifically at high-impact activities, the possibility of resuming sport and its consequences. The recommendations are essentially based on expert opinion.

Detailed Description
-----------------
The incidence of indications for hip and knee arthroplasty is constantly increasing due to an increase in arthrogenic risk factors and life expectancy. Projections predict an increase in the number of prosthetic surgeries between 2020 and 2030 of 150% for total hip replacements (THR) and 230% for total knee replacements (TKR). In younger patients, with a higher functional demand, resumption of physical activity and sport is a major objective after resumption of walking and pain management. They are also more likely to resume physical activities with high peak joint stresses, known as high-impact sports, most often against the advice of their surgeon. The repercussions of returning to sports after arthroplasty have been widely studied in the literature. These are essentially descriptive cross-sectional studies which show greater participation in low or medium impact sports activities in patients with prostheses. Few studies have looked specifically at high-impact activities, the possibility of resuming sport and its consequences. The recommendations are essentially based on expert opinion. Concerning trail running, a discipline in full expansion, particularly in the longest formats; a single study in 2019, involving 18 runners with a prosthesis, did not reveal any specific constraints compared to healthy runners during a 170 km ultratrail.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| To evaluate the impact of trail running on patients who have undergone prosthetic surgery (total or partial hip or knee arthroplasty) on the quality of life | This impact will be assessed using : -the EuroQol Group 5D-5L (EQ5D-5L) score (with 0 being yhe worst score and 100 the best score) | Day 1 | 
| To evaluate the impact of trail running on patients who have undergone prosthetic surgery (total or partial hip or knee arthroplasty) on physical activity | This impact will be assessed using : - UCLA (University of California, Los Angeles) score 10 (ranging from wholly inactive and dependent (level 1) to regular participation in impact sports (level 10)) | Day 1 | 
| To evaluate the impact of trail running on patients who have undergone prosthetic surgery (total or partial hip or knee arthroplasty) on hip problems | This impact will be assessed using : - the HOOS12 scale (Hip and Osteoarthritis Outcome Score) with 12 questions scored from 1 to 4 each, with 0 representing no hip problems and 4 representing extreme hip problems | Day 1 | 
| To evaluate the impact of trail running on patients who have undergone prosthetic surgery (total or partial hip or knee arthroplasty) on knee problems | This impact will be assessed using : - KOOS12 scale (Knee and Osteoarthritis Outcome Score) with 12 questions scored from 1 to 4 each, with 0 representing no knee problems and 4 representing extreme knee problems | Day 1 | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Functional scores of the hip and knee prostheses | Compare the functional scores of the hip and knee prostheses of these patients using the HOOS12 scale (Hip and Osteoarthritis Outcome Score) with 12 questions scored from 1 to 4 each, with 0 representing no hip problems and 4 representing extreme hip problems and the KOOS12 scale (Knee and Osteoarthritis Outcome Score) with 12 questions scored from 1 to 4 each, with 0 representing no knee problems and 4 representing extreme knee problems | Day 1 | 
| Pain and satisfactory level | Evaluate the pain and satisfaction of these patients after returning to running after a prosthetic surgery using the study questionnaire | Day 1 | 
| Rehabilitation and physical preparation | To analyse the rehabilitation and physical preparation of these patients that allowed them to return to sport after hip and knee prothesis implantation using the study questionnaire | Day 1 |
