Common Youth Leg Injuries
Why are Children's Injuries Different to Adults?Adolescent injuries differ from adult injuries, mainly because the bones are still growing. The growth plates (physis) are cartilaginous (strong connective tissue) areas of the bones from which the bones elongate or enlarge. Repetitive stress or sudden large forces can cause injury to these areas.
Common Adolescent Leg InjuriesIn the adolescent leg, common injuries include:
Osgood-Schlatter's DiseasePain at the bump just below the knee cap (tibia tubercle). Overuse injuries commonly occur here. The tibia tubercle is the anchor point of your mighty quadriceps (thigh) muscles. It is because of excessive participation in running and jumping sports that the tendon pulls bone off and forms a painful lump that will remain forever. This type of injury responds to reduced activity and physiotherapy. More info: Osgood Schlatter's Disease
Sinding-Larsen-Johansson DiseasePain at the lower pole of the knee cap (patella). Overstraining causes Sinding-Larsen-Johansson disease. It is because of excessive participation in running and jumping sports that the tendon pulls bone off the knee cap. This type of injury responds to reduced activity and physiotherapy. More info: Sinding Larsen Johansson Syndrome
Anterior Knee PainAnterior knee pain or patellofemoral syndrome frequently gets passed off as growing pains. Cause of this pain includes overuse, muscle imbalance, poor flexibility, poor alignment, or more commonly, a combination of these. Anterior knee pain is one of the most challenging adolescent knee injuries to sort out and treat. Accurate diagnosis and treatment with the assistance of a physiotherapist with a particular interest in this problem usually resolves the condition quickly. More info: Patellofemoral Pain Syndrome
Knee LigamentsThe cartilage between the leg bones have a better blood supply and are more elastic in adolescents than in adults. As adolescents near the end of bone growth, their injuries become more adult-like, hence more meniscal and ACL (anterior cruciate ligament) injuries are likely. MCL (medial collateral ligament) injuries result from a lateral blow to the knee. Pain felt on the inner side (medially) of the knee. MCL injuries respond well to protective bracing and conservative treatment. More info: Knee Ligament Injuries
ACL (anterior cruciate ligament) injuriesThis traumatic knee injury is significant. Non-contact injuries of the ACL are becoming more common than contact injuries of the ACL. Adolescent females are at high risk. Combination injuries with MCL or menisci are common. Surgical reconstruction is needed if the adolescent wishes to continue participating in "stop-and-start" sports. More info: ACL Injury
Meniscal injuriesYour meniscus is crescent-shaped cartilage between the thigh bone (femur) and lower leg bone (tibia). Meniscal injuries usually result from twisting. Swelling, catching, and locking of the knee are common. If physiotherapy treatment does not resolve these types of damages within six weeks, they may require arthroscopic surgery. More info: Meniscus Tear, Discoid Meniscus
Sever's DiseaseHeel pain is commonplace in young adolescents due to the stresses of their Achilles tendon pulling upon its bony insertion point on the heel (calcaneum). It is a common overuse injury as a result of excessive volume of training and competition, particularly when loads are increased dramatically in a short period. Diminished flexibility and muscle-tendon strength mismatching may predispose you. Physiotherapy, reduced activity, taping and orthotics are some of the best ways to manage this debilitating condition for the active young athlete. More info: Sever's Disease
Ankle SprainAn ankle sprain is probably the most common injury seen in sports. Ankles sprains involve stretching of the ligaments and usually occur when the foot twists inward. Treatment includes active rest, ice, compression and physiotherapy rehabilitation. An ankle sprain usually improves in 2-6 weeks with the correct treatment. Your ankle physiotherapist should check even simple ankle sprains. A residually stiff ankle post-sprain can predispose you to several other lower limb issues More info: Sprained Ankle
Patellar InstabilityPatellar (kneecap) instability can range from partial dislocation (subluxation) to dislocation with a fracture. Partial dislocation treatment is conservative. Dislocation with or without fracture is a much more severe injury and usually will require surgery. More info: Patella Dislocation
Osteochondritis DissecansThe separation of a piece of bone from its bed in the knee joint is Osteochondritis Dissecans (OCD). This injury is usually due to one major macro event with repetitive macro trauma that prevents complete healing. This injury is potentially severe. Treatment varies from rest to surgery. An Orthopaedic Surgeon's opinion is vital. More info: Juvenile Osteochondritis Dissecans (JOCD)
Growth Plate FracturesA fracture through the growth plate can be a severe injury that can stop the bone from growing correctly. These fractures should be treated by an Orthopaedic Surgeon, as some will require surgery.

The hip, elbow and ankle are the most common locations for lower limb avulsion fractures in the young sportsperson. Treatment of an avulsion fracture typically includes active rest, ice and protecting the affected area. This period of active rest is followed by controlled exercises that help restore range of motion, improve muscle strength and promote bone healing. Your physiotherapist should supervise your post-avulsion exercises. Most avulsion fractures heal very well. You may need to spend a few weeks on crutches if you have an avulsion fracture around your hip. An avulsion fracture to your foot or ankle may require a cast or walking boot. In rare cases, an excessive gap between the avulsed bone fragment and main bone may not rejoin naturally. Surgery may be necessary to reunite them. In children, avulsion fractures that involve the growth plates also might require surgery. All avulsion fractures should be reviewed and managed by your trusted physiotherapist or an Orthopaedic Surgeon.
