PREDICT-ACLv2: Association Between 4-Month Isokinetic Testing Measures and Second Knee Injuries After Primary Anterior Cruciate Ligament Reconstruction
Study Details
Study Description
Brief Summary
Anterior cruciate ligament (ACL) is a frequent and disabling injury in athletes. Most of the time, ACL reconstruction (ACLR) is consider for regaining function and returning to preinjury sports while reducing the risk of secondary injuries. However, the risk of secondary severe knee injury is increased after ACLR, especially in athletes returning to strenuous activities. If strength symmetry is considered as an important factor in the Return-to-sport (RTS) decision, there is conflicting data about the association between strength symmetry and the risk of second knee injury after ACLR. The main objective of this study was to test if knee muscles strength symmetry at 4 months was associated with the psychological readiness and incidence of subsequent severe injury of both knees at a minimum 2 years follow-up after ACL-R.

Outcome Measures
Primary Outcome Measures
- Change in Strength [ACL group: Two evaluations on both injured and healthy knees: 3-4 months after surgery; Routine practice following guidelines]]
Measurement of knee extensors and flexors peak strength (in newton.meter, Nm) on isokinetic dynamometer.
Secondary Outcome Measures
- Individual characteristics [ACLR group: Two follow-up medical consultations: (1) 4 months after surgery and (2) 2 years after the surgery for return to sport and reinjury;]
Personal characteristics recorded in the medical report as age, gender, type of sport and sport level of practice and return to sport after the surgery and severe reinjury on the operated knee or contralateral knee.
- Surgery characteristics [ACLR group: Two follow-up medical consultations 4 months after surgery]
Surgery characteristics recorded in the medical report as the type of surgery, the surgery duration
- Re-injuries [ACLR group: One evaluation with a minimum 2 years follow-up after the surgery]
Web based questionnaire about any sever knee injury (meniscus or ACL) after the primary ACLR
- Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale. [ACLR group: One evaluation with a minimum 2 years follow-up after the surgery]
Web based questionnaire with completion of the Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale.
