Brief Summary

Despite advances in surgery and rehabilitation, the return to sport after anterior cruciate ligament (ACL) reconstruction surgery remains a major challenge. challenge. Among the objective criteria retained, the isokinetic muscle strength assessment is an increasingly practiced evaluation and it is recommended to carry out follow-ups at 3-4 months (intermediate) and at 6-8 months (final) after surgery. However, the factors associated with muscle imbalance are uncertain and the threshold values of the intermediate isokinetic strength test (3-4 months) are inconsistent. In a retrospective analysis, the investigators aim to assess the predictive criteria for muscle imbalance after ACL reconstruction surgery.

Conditions

ACL - Anterior Cruciate Ligament Deficiency; Muscle Weakness

Outcome Measures

Primary Outcomes (1)

• Change in Strength

  Measurement of knee extensors and flexors peak strength (in newton.meter, Nm) on isokinetic dynamometer.

  ACL group: Two evaluations on both injured and healthy knees: (1) 3 months after surgery and (2) 7 months after surgery; Routine practice following guidelines

Secondary Outcomes (3)

• Individual characteristics

  ACL group: Two follow-up medical consultations: (1) 3 months after surgery and (2) 7 months after surgery; Routine practice following guidelines

• Injury characteristics

  ACL group: Two follow-up medical consultations: (1) 3 months after surgery and (2) 7 months after surgery; Routine practice following guidelines

• Surgery characteristics

  ACL group: Two follow-up medical consultations: (1) 3 months after surgery and (2) 7 months after surgery; Routine practice following guidelines

Study Arms (1)

ACL

All sports patients who had a muscle evaluation at 3-4 months and 6-8 months after ACL ligamentoplasty since January 2016

Eligibility Criteria

• Age: 16 Years - 55 Years
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64)
• Sampling Method: Non-Probability Sample

Study Population

All sports patients included in the sport medicine follow-up protocole with isokinetic muscular assessment at 3-4 months and 6-8 months after ACL reconstruction surgery since January 2016

You may qualify if:

• Patients who have had an ACL reconstruction surgery (isolated or associated with other meniscal or ligamentary surgery)
• Patient included in the sport medicine follow-up protocole with intermediate and final isokinetic muscular assessment at 3-4 months and 6-8 mnths after surgery respectively
• Patient who received the information form

You may not qualify if:

• Patient who did not participate in all follow-up consultations and isokinetic muscular assessments
• Cognitive or sensory impairment making it impossible to understand the information form
• Neurological, traumatic or osteoarticular history responsible for muscle imbalance prior to surgery
