Osgood Schlatter’s is an injury to the bony growth plate in the shin bone (tibia) just below the kneecap, which occurs in younger athletes. It is more a condition than a disease. Osgood–Schlatter’s disease occurs in children between the ages of 9–16 years.
Around 75% of cases affect boys and occurs in up to 20% of sporty children compared to 4% of a group of all activity levels. In a quarter of cases, both knees are affected and it is more likely to occur around periods of rapid growth. As the condition is due to irritation and damage of the growth plate, it can only occur while the growth plate is present, up to the age of 16 years approximately. Adults cannot get Osgood-Schlatter’s Disease as the growth plate closes over and turns into bone with skeletal maturity.
Mechanical factors play a big role in Osgood–Schlatter’s disease. When the feet are in ‘perfect’ alignment, the quadriceps muscles, patella tendon, patella and tibial tuberosity are all in a line. Any force created by using the thigh muscles transmits to the tuberosity in a direct, front-on direction. A pronated foot will increase the quadriceps angle in a similar way that a knock kneed position would. The change in the angle of pull can leave the trochanter more vulnerable from an angled pulling force.
Ignoring symptoms or adopting a ‘no pain, no gain’ attitude is likely to cause further damage and prolong recovery in patients with Osgood-Schlatter’s disease. Immediate, appropriate treatment in patients with this condition is essential to ensure a speedy recovery.
Some of the factors which may contribute to the development of
Osgood-Schlatter’s disease include:
● A sudden increase in training or sporting activity
● Inappropriate training
● Recent growth spurts
● Inappropriate footwear
● Muscle tightness or weakness (particularly the quadriceps)
Treatment techniques the Podiatrist may use
● RICE (Rest, Ice, Compression, and Elevation)
● Orthotics-The Podiatrist may discuss the use of foot orthotics as part of a treatment plan. This is especially important if there are biomechanical factors that exacerbate the tension on the patella tendon. This will help support the foot and reduce the effect of
biomechanical abnormalities such as an excessively pronated foot.
● Stretching—Advice on stretching the quadriceps & hamstrings.
● Recommence sport in a month or so
● Training changes—depending on your activities the podiatrist may recommend modifications to a training regime. Return to activity should be supervised by a qualified person such as a podiatrist or experienced adolescent coach.
