|---|---|
|
Aktiv komparator: Standard Rehabilitation
Standard meniscectomy rehabilitation including knee range of motion and strengthening exercises.
|
Standard rehabilitation will include interventions for typical knee impairments (effusion, knee motion deficits, lower extremity muscle weakness, and gait deviations) as well as advanced rehabilitation interventions as indicated (jump and agility exercises)
|
|
Eksperimentel: Standard Rehabilitation + Quadriceps intensive strengthening
The intervention includes high-intensity neuromuscular electrical stimulation and eccentric exercises for the quadriceps muscle in addition to the standard rehabilitation protocol.
|
Standard rehabilitation will include interventions for typical knee impairments (effusion, knee motion deficits, lower extremity muscle weakness, and gait deviations) as well as advanced rehabilitation interventions as indicated (jump and agility exercises)
Quadriceps intensive strengthening includes high-intensity neuromuscular electrical stimulation to the quadriceps muscle for 10 minutes and overload to the the eccentric phase of quadriceps strengthening exercises.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Change in International Knee Documentation Committee (IKDC) Subjective Knee Form Score
Tidsramme: Baseline (pre-surgery) to 7 weeks post-surgery (post-intervention)
|
The IKDC is a measure of self-reported knee function and includes items related to symptoms and functional activity.
Responses on the IKDC subjective knee form will be recorded on hard-copy and the summary score computed.
The highest (best) possible score is 100 points and the lowest (worst) possible score is 0 points.

Baseline (pre-surgery) to 7 weeks post-surgery (post-intervention)
|
|
Change in Tibial Articular Cartilage Volume
Tidsramme: Baseline (pre-surgery) to 1 year post-surgery
|
A magnetic resonance image (MRI) of the knee will be acquired and software will be used to quantify tibial articular cartilage volume.

Foranstaltningsbeskrivelse |
Tidsramme |
|---|---|---|
|
Single Leg Forward Hop Index
Tidsramme: 7 weeks post-surgery (post-intervention)
|
Three trials of the single leg forward hop will be collected on each side.
Distance will be averaged across trials.
The single leg hop index will be computed as [(distance on the surgical side/distance on the non-surgical side) *100]
|
7 weeks post-surgery (post-intervention)
|
|
Change in Urinary Concentrations of C-terminal Crosslinking Telopeptide of Type II Collagen (CTX-II)
Tidsramme: Baseline (pre-surgery) to 7 weeks post-surgery (post-intervention)
|
CTX-II is a biomarker of Type II collagen degradation.
Early-morning, second void, fasting urine samples will be collected and stored.
Concentrations of CTX-II will be determined with enzyme-linked immunosorbent assay, corrected for creatine concentration, and log-transformed.
Creatinine concentration will also be determined with enzyme-linked immunosorbent assay.
