Chondromalacia Patella

Updated: Dec 24, 2024




















Pathology

The patella slides up and down in the femur groove when the knee joint is extended. If you frequently perform weight-bearing knee bending exercises for a long period, or if the patella is misaligned, the cartilage under the patella may be overloaded and worn.


Causes

  • Repeated long weight-bearing movements of the knee

  • Standing in high heels for a long time will cause the knee joint to hyperextend

  • Tight quadriceps, insufficient strength, and imbalance of inner and outer muscle strength

  • Trauma

  • Poor gluteal muscle strength


Symptoms

  • There is a grinding sound or feeling when the knee joint is bent

  • Pain worsens when going up or down stairs or bending the knee

  • In severe cases, the knee joint may become swollen and stiff

  • Knees are sore and weak during weight-bearing movements


Treatments

  1. Interferential Current Therapy: Anti-inflammation, pain relief, and removal of knee edema

  2. Ultrasound: Deep heating and accelerates tissue repair

  3. Shockwave: Break up tendon calcification and induced rotator tendon repair

  4. Sports Therapy: Improve gluteal muscle strength and avoid excessive knee dominance

  5. Acupuncture: Relieve quadriceps tension and adjust internal and external balance

  6. Taping: Improve the patellar sliding track


Consequences/Grading of Not Treating Early

Level 1: Local cartilage softens and color changes slightly

Level 2: The local cartilage surface is slightly uneven, with some small cracks or fibrosis.

Level 3: The cracks on the cartilage surface extend deep into the hard bone beneath the cartilage, and the cartilage forms a crab-like surface.

Level 4: The cartilage is gone and the subchondral hard bone is exposed and worn away
