Condition(s) studied

Investigational drug(s) / intervention(s)

Novel program: Applying new training method; the Nordic hamstring exercise

Traditional program: Conventional rehabilitation training administered

Study summary

Scientific Research Question

Overall Purpose:

Regarding rehabilitation after anterior cruciate ligament reconstruction (ACLR), there is a knowledge gap - a lack of evidence. Important questions such as how rehabilitation should be structured, what it should include, and how it should be evaluated are currently not clear. Therefore, the investigators plan to conduct a two-year follow-up randomized controlled trial (RCT) on post-ACLR rehabilitation.

Moreover, detailed information on how/under what circumstances the ACL injury occurred is not satisfactorily described in the literature. Therefore, the investigators are planning a new survey that can identify, explain, and prevent the risk factors causing a person to suffer from an anterior cruciate ligament injury.

Specific Objectives:

How should guidelines for rehabilitation after ACLR be structured, what should they include, and how should they be evaluated to best restore knee function in the patient? Can a detailed and comprehensive survey identify, explain, and prevent the risk factors causing a person to suffer from an ACL injury?

Eligibility

Primary outcome measure(s)

• Isokinetic muscle strength — Tests at 8, 12, 18 and 24 months post-ACLR.
  Test of each patient's unilateral maximal isokinetic muscle strength for the involved and the uninvolved leg, using an isokinetic dynamometer (Biodex isokinetic dynamometry system 4).
• Single-leg hop performance — Tests at 8, 12, 18 and 24 months post-ACLR.
  Test of each patient's single-leg hop performance for the involved and the uninvolved leg. The goal is to have a less than 10% difference in hop distance between the injured limb and uninjured limb.
