Sinding Larsen Johansson Syndrome – Explained

Sinding Larsen Johansson Syndrome is a juvenile osteochondrosis which disrupts the attachment site for the patella tendon. It is caused by overuse of the knee extensor mechanism, resulting in inflammation to the inferior portion of the patella and its tendinous insertion on the tibia. This is most commonly seen in active boys (10-13 years) but can also affect younger girls during the adolescent growth spurt.

Symptoms affect the front of the knee and include:

  • Localised pain
  • Swelling
  • Tenderness

All of which worsen on exercise, stair climbing, squatting, kneeling, jumping and running. Patients can present with a limp as the condition progresses and in some cases it can affect both knees. Symptoms are usually relieved by rest.

Recovery through Physiotherapy

At Jonathan Clark we offer progressive physiotherapy treatment to manage your injury and allow you to return to normal activity levels. Our therapists provide advice and therapeutic input including the following:

 

  • Knee Load Management; limiting participation in high impact activities (preferred sports include swimming, cycling or cross training), infrapatella knee strap to dissipate forces away from the painful area & kinesiology taping to offload the tendon and provide pain relief
  • Functional training; therapeutic exercises, stretches, massage & foam rolling to reduce tightness of quadriceps, ITB, hamstrings, hip flexors and calf muscles
  • Strength training; involving glutes, quadriceps, hamstrings and calves
  • Assessment of lower limb; including proprioception, foot arch position and corrective exercises for dynamic foot control
