is a degenerative and functional joint condition in which normal knee joint function gradually changes, affecting the condition of joint cartilage, muscular and ligament structures, and movement biomechanics.

The knee joint is one of the most heavily loaded joints of the musculoskeletal system. It plays a major role in:
walking
running
body weight support
stair climbing
body stabilization during movement
With osteoarthritis, gradual changes may affect:
shock absorption properties
mobility
stabilization
load distribution
movement coordination
In many cases, osteoarthritis development is associated with:
age-related changes
joint overload
impaired walking biomechanics
weakness of stabilizing muscles
posture dysfunction
excess body weight
insufficient physical activity
previous injuries
Over time, changes in knee joint mechanics may affect:
pelvic alignment
posture
spinal function
lower extremity stabilization
overall movement balance
In some cases, people begin to:
alter walking patterns
reduce physical activity
compensatorily overload other joints and spinal regions
This may further affect:
movement control
coordination
tolerance to physical load
muscle balance
For this reason, knee osteoarthritis rehabilitation should focus not only on the joint itself, but also on comprehensive assessment of:
movement biomechanics
posture
stabilization
lower extremity function
overall musculoskeletal condition.
Causes and Symptoms of Knee Osteoarthritis
Knee osteoarthritis develops gradually because of degenerative joint changes, knee overload, and impaired movement biomechanics.
The knee joint constantly participates in:
walking
running
stair climbing
body weight support
lower extremity stabilization
When load distribution becomes impaired, gradual changes may affect:
joint cartilage condition
joint stabilization
muscular and ligament function
knee mobility
movement coordination
Main Causes
Knee osteoarthritis is most commonly associated with:
age-related degenerative changes
joint overload
excess body weight
weakness of stabilizing muscles
impaired walking biomechanics
posture dysfunction
insufficient physical activity
prolonged static loading
previous knee injuries
overload of the lower extremities
Additional contributing factors may include:
flat feet
altered lower limb alignment
impaired pelvic stabilization
repetitive microtrauma
excessive physical loading
Main Symptoms
Knee osteoarthritis may be associated with:
knee pain
movement stiffness
discomfort during walking
joint cracking or clicking
rapid leg fatigue
restricted mobility
feeling of instability
muscular tension around the knee
reduced endurance during physical load
In some cases, symptoms may also include:
discomfort after prolonged sitting
pain during stair climbing
overload of the opposite leg
altered walking pattern
feeling of stiffness after rest
Because of discomfort, people often begin to:
reduce movement activity
limit physical activity
alter walking biomechanics
compensatory overload the pelvis, lumbar spine, or opposite leg
This may further affect:
posture
stabilization
movement coordination
muscle balance
tolerance to physical load
For this reason, comprehensive assessment of lower extremity function, posture, and movement biomechanics is important.
Diagnosis
Diagnosis of knee osteoarthritis is based on comprehensive assessment of:
knee joint function
joint mobility
lower extremity stabilization
walking biomechanics
muscle balance
load distribution during movement
During the consultation, the specialist evaluates:
pain location
range of motion
joint stability
walking pattern
condition of the muscles surrounding the knee
pelvic and lower extremity alignment
joint response to physical load
Additional diagnostic methods may include:
knee joint X-ray
MRI
joint ultrasound
orthopedic examination
functional testing
additional instrumental examinations
At Spine Ambulatory physical therapy and massage centers, special attention is given not only to the joint itself, but also to:
movement biomechanics
posture
stabilization
coordination
spinal and lower extremity function
Timely diagnosis helps identify functional disorders and develop an individualized physical therapy and rehabilitation program.
Knee Osteoarthritis Treatment
Physical therapy and rehabilitation programs for knee osteoarthritis are individually adapted according to:
severity of functional changes
symptom intensity
joint mobility level
lower extremity stabilization
walking mechanics
physical activity level
In most cases, the primary focus is placed on:
improving joint mobility
knee stabilization
restoring movement biomechanics
improving muscle balance
adaptation to physical load
preventing further joint overload
At Spine Ambulatory physical therapy and massage centers, rehabilitation programs are aimed at:
