Knee Pain

The knee joint is a complicated joint of the human body. The joint bears the body weight and allows performing various activities against the pull of gravity. Examples are standing, walking, running / jogging, climbing the stairs and other. It also acts as the shock absorber of the body.

The knee joint comprises of three bones: the thigh bone (femur), shine bone ( tibia) and knee-cap bone (patella). The capsules and ligaments (medial, lateral, collateral ligaments) strengthen the joint.

The anterior and posterior cruciate ligaments tie all the bones together and hold them in place from inside the joint. The articular cartilages exist between the femur and meniscus and under the patella.

Other structures also support the joint to reduce friction and absorb shock. The synovial fluid lubricates the joint. The fat pad (bursai) structure provides the cushioning effect.

The muscles around the knee joints facilitate their motion and keep them in proper alignment to transfer the body weight to the ground.

Common Knee Injuries

As the knee is involved in the body movement, it is vulnerable to injuries. The knee joint injuries can be classified as:

Acute: Acute / sudden injuries are due to rotating or twisting of the knee or a direct blow to the knee joints, resulting in torn ligaments, tendon, cartilage or muscle and fracture. Sports that require sudden stopping or jumping can also cause acute knee injuries.

Overuse: It includes muscle strain, tendonitis and bursitis. Overuse of the knee joint may also lead to a swollen knee.

Degenerative: Such injuries are the osteoarthritis of the knee joint and result in the breaking down of the cartilages. Eventually, the bone surface becomes rough and irregular and the joint space reduces.

Infectious diseases like septic arthritis, polyarthritis and autoimmune diseases like rheumatoid arthritis can also affect the knee joints.

Knee Pain Causes

Sports activities and injuries: Excessive exercise without proper warming up or cooling down, running, jumping and high-pressure generating exercises like climbing up / down the stairs, squatting, weight lifting and gym knee exercises against the resistance irritate and lose the cartilage lining under the surface of the knee-cap bone (patella) causing knee injury and pain (runners knee).

Change in the alignment of knee joint:

Change of alignment of knee joint or body posture: Due to tightening of muscles or abnormality of the foot, ankle, knee and hip joint changes its normal alignment. Alignment abnormalities distribute abnormal pressures at knee joint and eventually injured structures in and around the knees.

All the muscles which controls the knee movements get attached with shin bone( tibia) and some of the muscles get attached to knee cap bone( patella) as well. Any tightness or shortening due to spasm or trigger point pain will alter the alignment or pull the shine bone (tibia) or patella.

Tight TFL band: is a fibrous band that attaches from the side and top of the hip bone to the side of tibia bone and patella) tightness can cause bad knee pain and awkward walking style. The tight band pulls and rotates leg to the outside, and shifts the patella up(patella alta) and outwards with the legs turned out instead of facing straight forward, which leads to rolling in of feet as a part of compensation which results severe knee pain and an awkward walking style.

The tightness of other muscles around the knee also causes alignment abnormalities and leads to damage of knee. Tight quadriceps pulls the patella abnormally and can increase the pressure on the kneecap causing pain. Tight hamstrings pulls knee in to hyper extension while standing also can create excess stress on the patella.

The foot deformities: also have a direct influence on the knee joint. Persons who bear more weight on the inside of the feet or turn it inwards can have the same problem mentioned above. It can result from tight calf muscles, tight TFL band, and tight plantar fascia band at the bottom of the foot.

The knee abnormalities can affect the hips, lower back and neck and vice versa.

Improper Footwear: These can also cause alignment problems. Over a period, misalignment seriously damages the foot, resulting in knee pain.

Congenital Diseases: The incorrect alignment untreated in congenital problems (Genu Valgum, Genu Varum and Genu recurvatum) will lead to early degenerative changes of the knee and, finally, knee osteoarthritis and permanent deformities.

Trigger point formation and muscle spasm: Repetitive overuse, existing trauma or micro trauma or radiating pain from other sites can facilitate the formation of trigger points or muscle spasm over the surrounding muscles of the knee joint.

The formation can alter the normal length-tension of the muscles. Since these generate radiating pain or create tenderness during rest or activities, victims may start using inappropriate muscles for the desired action rather than the normal muscles.

Because the knee joints have all the muscles required for knee activities, the above changes create excess stress and pain at the joints. Finally, patients may have alignment alterations and early degenerative changes.

Knee Joint Osteoarthritis / Degenerative Joint Disease: It causes the articular cartilage to breakdown within the joint.

As the disease progresses, due to wear and tear, the articular cartilage becomes thinner. Sometimes it is also torn. The effects are pain and inflammation, night cry and morning stiffness.

If the osteoarthritis becomes severe, it affects normal activities like walking, climbing stairs, squatting, and other.

In extremely severe cases, the disease reduces the joint space. Also, the bone surfaces may contact together. All these lead to deformity of the joints and a loss in the range of motion of the same.

Body weight: Increased body weight may create undue stress on the knee joint. It may not be able to hold the sudden increase in body weight.

Frozen knee joint: It causes pain due to decreased normal bio-mechanical motion of the knee joint.

Lower-back problems: The nerves which supplies the knee joint come from the lumbar region (L2-L4). Problems like disc prolapse, dysfunction, arthritic changes at this site might irritate the nerve function, resulting in knee joint pain.

Treatment Comparison for Knee Pain

Conventional treatment

  • Treatment emphasizes on masking the pain by using strong pain killers and other drugs like cortisone injection
  • Long term use of knee pain drugs has serious side-effects
  • Once you stop taking medicines, chances of knee pain recurrence are high
  • Treatment concentrates only on knee joints
  • Recommends surgery for moderate and severe arthritis

Physio Fusion Therapy (PFT)

  • PFT emphasizes on “finding the source of the problem and rectifying it, using natural means, which doesn’t prescribe drugs.
  • Absolutely no side-effects
  • Speedier recovery
  • No diet restrictions
  • Chances of pain recurrence is very low if you follow the instructions and perform the exercises after recovery by PFT
  • The treatment concentrates on the affected and surrounding areas
  • Avoids knee replacement surgery in many cases of severe arthritis
  • Prior physiotherapy helps in replacement surgery and speedy recovery in cases where surgery cannot be avoided
  • Some of the arthritis like rheumatoid arthritis, Ankylosing spondylitis and gout arthritis needs medication as prescribed by your doctor in addition to PFT

Do you still have Knee Pain even after Replacement Surgery?

The surgery replaces your knee, but doesn’t consider the effects of muscles on your knee pain.

Due to your earlier, severe pain and deformity, muscles might have lost their normal quality. Further, trigger points and muscle spasm are still present. All these cause continued knee pain.

PFT muscle normalization methods and exercises will give you more flexibility, pain relief and help you perform activities with ease.
