NCT05464485

Brief Summary

Anterior Cruciate Ligament (ACL) reconstructions using hamstring grafts can be performed using one or two hamstring grafts, the semitendinosus (ST) tendon only, or both the semitendinosus and gracilis (ST/G) tendon. As most patients strive to return to sport nine months after reconstruction the purpose of this study was to compare the recovery of hamstring muscle strength during these first nine months after reconstruction using the ST or ST/G tendons.

Outcome Measures

Primary Outcomes (1)

  • Isokinetic muscle strength deficit

    Comparing isokinetic muscle strength deficit (measured at 60°/s, 180°/s and 240°/s flexion with a the Biodex dynamometer) between both groups

    38 weeks post-surgery

Secondary Outcomes (1)

  • Change in isokinetic muscle strength deficit

    12, 20 and 38 weeks post-surgery

Study Arms (2)

ACL hamstring reconstructions using semitendinosus (ST) tendon only

Procedure: ACL hamstring reconstructions using semitendinosus (ST) tendon only

ACL hamstring reconstructions using semitendinosus and gracilis (ST/G) tendon

Procedure: ACL hamstring reconstructions using semitendinosus and gracilis (ST/G) tendon

Interventions

ACL reconstruction with a ST tendon graft received a reconstruction according to the Tape Locking Screw technique (FH Industrie, Quimper, France) with a dedicated interference screw

ACL hamstring reconstructions using semitendinosus (ST) tendon only

ACL reconstruction with a ST/G tendon graft received a reconstruction with the anteromedial portal technique with endobutton fixation (Smith \& Nephew, London, UK).

Healthy VolunteersYes
Age GroupsAdult (18-64)
Sampling MethodProbability Sample
Study Population

Patients will be recruited from the Orthopaedic outpatient clinic of the Isala in Zwolle if the patient has an ACL rupture and if there is an indication for surgical reconstruction with the AMP or TLS ACL reconstruction technique or at the (standard) 6 weeks follow-up appointment after AMP or TLS ACL reconstruction surgery

You may qualify if:

  • Patient older than 18 years and younger than 60 years old.
  • Mentally competent to understand the informed consent.
  • Patient underwent AMP or TLS ACL reconstruction surgery or will undergo AMP or TLS ACL reconstruction surgery

You may not qualify if:

  • ACL reconstruction surgery older than 12 weeks.
  • Meniscus rupture larger than 25%
  • Indication for meniscal repair.
  • Injury of the collateral ligaments or posterior cruciate ligament
  • History of ACL or meniscal rupture
  • Neurological or systemic disorder that inhibit adequate rehabilitation
