Abstract
Osteoarthritis is a degenerative joint disease occurring primarily in older persons and predominantly
affecting medial tibiofemoral compartment leading to pain, loss of function and reduced quality of life.
During walking, forces across the knee joint are not transmitted equally between the medial and lateral
compartments. Increased mechanical load and damage to the medial side of the knee joint has been
associated with increasing knee varus alignment, further loading the medial compartment which causes
symptoms of medial knee osteoarthritis. This study was aimed to determine the effects of neuromuscular
exercises for improving pain and physical function in patients with medial knee osteoarthritis. 30 subjects
with medial knee osteoarthritis that fulfilled the inclusion criteria were randomly assigned into 2 groups;
15 in each group. Control group received conventional treatment and experimental group received
neuromuscular exercises along with conventional treatment. The treatment duration was 45 minutes in
each session for 6 days in a week and the trial stretching 8 weeks. Statistical analysis of inter group
significance by independent sample t-test for WOMAC [t=2.356>table value, t= 2.048], isometric knee
extension [t=7.941>table value, t=2.048] and Mann-Whitney test for VAS [p=0.007] reveals that
experimental group showed significant difference between pre-test and post test values of WOMAC,
isometric knee extension and VAS than the control group. Both groups show significant difference in
their pre and post–test values. Participants with medial knee osteoarthritis in the experimental group that
received neuromuscular exercise along with conventional treatment show greater improvement in pain
and physical function. The findings of this study reveal a more effective exercise treatment option than
currently exists for this important subgroup of people with knee osteoarthritis.

Introduction
Osteoarthritis (OA) is a degenerative joint disease occurring primarily in older person,
characterized by erosion of the articular cartilage, hypertrophy of the bone at the margins that
is osteophytes, subchondral sclerosis and a range of biochemical and morphological alteration
of the synovial membrane and joint capsule
[1]
. Knee osteoarthritis predominantly affecting the
medial tibiofemoral compartment, is a common chronic condition leading to pain, loss of
function and reduced quality of life
[2]
. The prevalence of OA increases with age. Men are
affected more commonly than women before 50 years of age whereas after 50 years of age the
prevalence in women is 2-3 times greater than men
[3]
. OA is the second most common
rheumatologic problem and the reported prevalence of knee OA in elderly in other studies is
done in India ranged between 32% and 64%
[4]
. The associated factors were found to be female
gender, obesity, age and sedentary work
[5]
. OA can be diagnosed by radiographic changes
and/or by typical clinical symptoms. Radiographic findings which identify OA include
osteophyte formation along the joint margins, joint space narrowing, subchondral sclerosis and
cyst formation. Presence of osteophytes is the most specific radiographic marker of OA,
although osteophytes are not present in early disease
[6]
. The knee joint is a complex structure
with three joint compartments, including the medial and lateral tibio-femoral compartments
and patella-femoral joint. During walking, forces across the knee joint are not transmitted
equally between the medial and lateral compartments.
