Brief summary
The disease Osgood-Schlatter is most commonly found in sports teenager growing up apophysose accounting for 28.4% of osteochondrosis by Breck. It relates to 62% of osteochondrosis knee and affects adolescent girls between 10 and 12 and boys between 12 and 15 It is usually considered a benign pathology that cures in the majority of cases. However, in 5-10% of cases there is persistent residual pain in adulthood. The classic complication is the avulsion fracture of the tibial tuberosity in adolescents who continued his sports without restriction. The possible consequences are numerous including the presence of a free bone fragment at the insertion of the tendon originally described by Osgood the establishment of a genu recurvatum, a high kneecap or patella alta and an enlarged tibial tuberosity (ATT) annoying sport. The main two treatments are complete rest from sport activity or cast immobilization. The main objective is to compare these two technics according to the proportion of full sporting recovering at 12 months
Interventions
Patients in this group will have their knee locked with a resin going from the ankle to the top of the thigh for 4 weeks, followed by 4 weeks without cast but with rehabilitation through physiotherapy.
Patients included in this group will follow the current standard procedure for this disease that is to say complete sport rest during 8 weeks including rehabilitation through physiotherapy, following the exact same technic as the experimental group .

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Restarting a sporting activity | 12 weeks after intervention | Comparison between the 2 groups of the proportion of patient returning to sports activity 12 weeks after treatment. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Pain killer consumption | follow-up visit week 4 | Evaluation of pain killer consumption (type, dose ,frequency) between the 2 groups |
| Quality of life assessment | inclusion visit Day 0 | Quality of life will be assessed using the SF-12 auto questionnaire |
| Activity level assessment | inclusion visit Day 0 | Activity level will be assessed using the Tegner scale |
| complete sport rest compliance assessment | follow-up visit week 4 | The complete sport rest compliance will be assessed using a visual analogic scale (0 to 10, 0 will be a complete rest compliance) |
| painfulness due to immobilization cast | follow-up visit week 12 | The patient in the cast immobilization group will be asked what was the level his/her level of cast tolerance: bad, average, good or very good. |
| Anterior tibial tuberosity pain | Inclusion visit Day 0 | Mean pain evaluation using Visual analogic scale between the 2 groups, at Anterior tibial tuberosity palpation |
| Patella size | inclusion visit Day 0 | The patella size will be measure on the lateral radiograph using the Caton and Deschamp index |
| Radiographic evolution of Osgood Schlatter disease | follow-up visit week 12 | Both clinicians and radiologist will evaluate separately the evolution of Osgood Schlatter disease using a new classification. It is based on 3 parameters: anterior tibial tuberosity fragmentation, thickening of soft tissues and presence or not of an ossicle. |
| Potential return to sport activity | follow visit week 8 | After a week of training, patients of each group will be evaluated and the clinician will consider the possibility of a potential return to sport activity the week 8 of follow-up |
| Return to sport activity at the initial level | follow visit month 6 | Six months after the intervention, patients will be called to evaluate if they were able to return to a sport activity at the same level they were before the disease. This proportion will be compared in between both groups |
| alternative options during the study | follow visit month 6 | Each patient will be ask during the phone interview at 6 months if the consulted another physicians or if they used an alternative to that proposed in our study. |
| Quadricipital shortness | inclusion visit Day 0 | The Quadricipital shortness will be evaluated thanks to the knee flexion angle will be measured using the modified Thomas test as well as hamstring muscles length measured using the popliteal angle |
