Summary
Knee joint biomechanics during jogging showed no significant differences between the operated leg and the control leg after arthroscopic partial meniscectomy (APM). However, the non-operated leg exhibited higher knee moments, suggesting potential clinical implications for the contralateral limb.
Area of Science:
- Orthopedics
- Biomechanics
- Sports Medicine
Background:
- Altered knee joint biomechanics are implicated in knee osteoarthritis pathogenesis.
- Previous studies reported biomechanical changes post-arthroscopic partial meniscectomy (APM).
- Understanding jogging biomechanics post-APM is crucial for assessing long-term knee health.
Purpose of the Study:
- To investigate knee joint biomechanics during jogging.
- Compare patients 3 months post-APM with a healthy control group.
- Assess changes at baseline and 2-year follow-up.
Main Methods:
- Controlled laboratory study utilizing 3D motion analysis.
- Evaluated 78 patients post-medial APM and 38 healthy controls at baseline.
- Assessed 64 patients and 23 controls at 2-year follow-up, analyzing peak knee moments and flexion angle during barefoot jogging.
Main Results:
- No significant differences in knee joint moments or flexion angle were observed between the APM leg and the control leg.
- The non-APM (contralateral) leg showed a 35% higher normalized peak knee adduction moment compared to controls.
- Kinematic differences, such as a 1.4° lower peak knee flexion angle in the APM leg, were small and of questionable clinical relevance.
Conclusions:
- Knee joint biomechanics during jogging are not significantly altered in the operated leg post-APM compared to controls.
- Elevated knee moments in the non-APM leg warrant further investigation due to potential clinical implications.
- Findings support future research on the impact of jogging on knee health in patients post-APM.
