Knee Pain.
Symptoms, 11 diagnostic tests, treatment, and a 5-stage rehab program — everything about knee pain care in one place.
What Is Knee Pain?
Knee pain is caused by damage or tearing of knee structures such as ligaments, cartilage, and tendons.
It can result from various causes, including sports injuries, trauma, repetitive stress from work, or age-related degenerative changes.
Common Symptoms of Knee Pain
Sharp Pain
Sharp pain in the front or inner knee when climbing stairs or standing up from a seated position
Swelling · Warmth
Joint swelling or warmth; in severe cases, visible knee deformity or an abnormal gait
Joint Stiffness
Stiffness after waking up or sitting for a long time, which eases with movement
Crepitus · Weakness
Grinding or popping sounds, a sensation of something being caught, and sometimes sudden weakness
Common Diagnostic Tests
Damage to any of the knee's anatomical structures can cause pain. After an initial diagnosis based on medical history and physical exam, we run further tests to confirm it.
Medical History
HistoryWe ask about aggravating and relieving factors, and when the pain began.
Physical Examination
Physical ExamChecking for redness and swelling, tenderness, pain on flexion/extension, and range of motion
X-ray
X-RayIdentifies fractures, bone spurs, arthritis, and bone tumors to determine whether surgery is needed
Ultrasound
UltrasoundReal-time check of ligaments, tendons, meniscus, and joint fluid
MRI
MRIDetailed diagnosis of cruciate ligament, meniscus, and bone marrow edema
CT
CT3D imaging of complex fractures to plan surgery
Thermography
ThermographyMaps heat distribution over inflamed areas to guide treatment
Blood Test
Blood TestHelps distinguish rheumatoid arthritis, gout, and infectious arthritis
Joint Fluid Aspiration
Joint AspirationPerformed when swelling is present, to check for inflammation, infection, or gout
Nerve Conduction Study & EMG
EMG · NCVChecks for nerve compression or neuropathy to determine if nerve block or decompression is needed
Bone Density Test
BMDAssesses the risk of osteoporotic fracture.
Common Treatment Methods
Nerve Block
Prolotherapy
Functional Intramuscular Stimulation (FIMS)
Trigger Point Injection
Exercise Therapy · Rehabilitation
5 Stages of Rehab Exercise
Strength Training
Stretching-Focused Relaxation
5-Stage Rehab Program
Initial Stage
- 01Light stretching that doesn't strain the joint
- 02Slowly repeating knee bend-and-extend movements
- 03Gently stretching the quadriceps and hamstrings
- 04Improving blood circulation to speed recovery
Middle Stage
- 01Begin strength building once pain has eased
- 02Leg raises (lying down or seated)
- 03Knee curls while lying face down
- 04Progress gradually from bodyweight to resistance bands to light weights
Functional Exercise
- 01Gradually increasing weight-bearing load
- 02Wall squats and chair squats
- 03Practicing everyday movements
- 04Climbing stairs (starting slowly)
Balance
- 01Practicing standing on one leg
- 02Balancing on unstable surfaces
- 03Relearning cerebellar coordination
- 04Preventing falls and muscle cramps
Aerobic Exercise
- 01Swimming and water walking
- 02Stationary cycling
- 03Minimizing impact on the joint
- 04Improving cardiovascular fitness and managing weight
