Effect of medial meniscectomy on gait parameters

Abstract

The aim of this study is to determine how selected gait parameters may change as a result of medial meniscectomy at constant gait speed. Gait analysis using a ZEBRIS ultrasound based three-dimensional motion analysis system was performed in 24 patients who had undergone medial meniscectomy 18 months before the gait analysis. The constant gait speed was 3.5 km/h. Muscle activity was measured by the surface EMG system connected to the system. The muscle groups involved in the tests included (1) m. vastus medialis and (2) lateralis, (3) rectus femoris, (4) m. biceps femoris, (4) m. adductor longus, (5) m. gluteus medius, (6) m. gastrocnemius medialis and (7) lateralis. The spatial-temporal, angular parameters and intermuscular coordination determined are compared to the gait parameters of 51 healthy subjects. The study showed that medial meniscectomy resulted in a change of limb dominance; reduced knee joint motion was compensated by the increased motion of other joints in the kinematic chain-hip joint of the opposite side, pelvic obliquity-and the gait (spatial-temporal parameters) was symmetrical, with no significant differences compared to spatial-temporal parameters of healthy groups. Our study showed that the medial meniscectomy could result in adductor-free gait and reduce the rotation motion of the pelvis.

Quadriceps Activation Following Knee Injuries: A Systematic Review

“…37 Abnormal gait kinematics and kinetics are common after knee injuries such as ACL reconstruction [38][39][40] and meniscectomy. 41 Altered gait patterns after knee joint reconstruction may persist for 8 39 to 12 42 months and for years after major joint trauma and reconstruc- 17 2001 (ACLr) Urbach and Awiszus, 22 2002 (ACLd) Williams et al, 21 2002 ( tion. 43 Evidence also exists of altered lower extremity kinetics during a seated leg press 44 and during gait 32,45 after an artificial knee joint effusion.…”

The Effectiveness of Postoperative Physical Therapy Treatment in Patients Who Have Undergone Arthroscopic Partial Meniscectomy: Systematic Review With Meta-analysis

“…42 Despite the minimally invasive nature, studies have shown that patients undergoing arthroscopic meniscectomy have pain, effusion, loss of range of motion (ROM), functional changes, neuromuscular and biomechanical changes, loss of quadriceps muscle strength, and a reduced quality of life. 5,8,12,13,27,30,31,33 Herrlin et al 17 showed that for middleaged patients with simple lesions in the meniscus, physical therapy has yielded T T STUDY DESIGN: Systematic review with metaanalysis.…”

The reiterative accuracy of gait determined by simplified gait analysis

“…The average of individuals' spatial and temporal parameters (Table 2) are not analysed here as they have already been published in detail [8,17,21]. In summary, we can establish that the spatial and temporal parameters depend on age, sports, and the different orthopaedical diseases.…”

“…Since ultrasound-based measuring and recording techniques were developed, gait analysis has been frequently used in almost all fields of human locomotion [18]. An ultrasound-based measuring system is used for functional performance assessment after treatment or surgery such as anterior ligament reconstruction surgery [20], meniscectomy [21], hip [17] and knee arthoplasty [7]. The system is useful for analysing the effects of osteoarthrithis [8] and sports [19].…”
