Knee Joint01:23

Knee Joint

The knee joint is the most complicated joint in the body. It consists of three articulations– two tibiofemoral and one patellofemoral. As is characteristic of synovial joints, the knee joint has a thin articular capsule that partially surrounds this joint cavity. Additionally, several ligaments, muscles, and cartilaginous structures support the movement of the knee.
A total of seven ligaments support the knee joint. The patellar ligament, which is also attached to the quadriceps femoris group...

Summary

Muscle strength and activation deficits before knee surgery are linked to pain, swelling, and tear type. Identifying these factors preoperatively helps predict outcomes and tailor rehabilitation for better knee function.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Biomechanics

Background:

  • Preoperative knee function impacts rehabilitation success after arthroscopic meniscectomy.
  • Understanding factors influencing strength and muscle activation deficits is crucial for patient stratification.

Purpose of the Study:

  • To investigate the relationship between preoperative knee strength/muscle activation deficits and clinical/anthropometric factors.
  • To identify predictors of poor isokinetic performance in patients undergoing meniscectomy.

Main Methods:

  • Evaluated 34 patients pre-arthroscopic meniscectomy using isokinetic knee testing (30°/s and 180°/s).
  • Assessed strength (work) and muscle activation (EMG) deficits.
  • Correlated deficits with pain, effusion, meniscal lesion type, atrophy, symptom duration, and age.

Main Results:

  • Moderate correlation found between work and EMG deficits, indicating reduced muscle activation contributes to decreased output.
  • Pain severity was the strongest predictor of work and EMG deficits.
  • Knee effusion, thigh atrophy, meniscal tear type, and age also showed predictive value.

Conclusions:

  • Older patients (>45 yrs) with bucket-handle tears, effusion, atrophy, and severe pain are at higher risk for poor preoperative knee performance.
  • Preoperative identification of at-risk patients is essential for optimizing rehabilitation strategies.
