[[Image:Osgood-Schlatters.PNG|thumb|right]]Osgood-Schlatter's disease is a traction apophysitis at the level of the tibial tubercle due to repetitive strain on the secondary ossification center of the tibial tuberosity. The repetitive strain is from the strong pull of the quadriceps muscle produced during sporting activities. The tibial tuberosity avulsion may occur in the preossification phase or the ossified phase of the secondary ossification center. Once the bone or cartilage is pulled away it continues to grow, ossify and enlarge. The intervening area may become fibrous, creating a separate persistent ossicle or may show complete bony union with some enlargement of the tibial tuberosity.&nbsp;It occurs more often in boys. These traction apophysitises are probably one of the most encountered overuse injuries in children and adolescents.<ref>Kaya DO, Toprak U, Baltaci G, Yosmaoglu B, Ozer H.

[[File:Jumping.jpeg|right|frameless]]
OSD  usually develops during the stage of bone maturation (10-12 yrs in girls and 12-14 yrs in boys) . The underlying etiology can be attributed to the repeated traction over the tubercle leading to microvascular tears, [[fracture]]<nowiki/>s, and [[Inflammation Acute and Chronic|inflammation]]; which then presents as [[Oedema Assessment|swelling]], [[Pain Assessment|pain]], and tenderness.


== Epidemiology /Etiology  ==
OSD is an [[Overuse Injuries in Sport|overuse injury]] that mostly appears in active, adolescent patients. The repetitive strain and microtrauma results in irritation and in severe cases partial avulsion of the tibial tubercle apophysis. Rarely trauma may lead to a full avulsion fracture. Predisposing factors include poor flexibility of quadriceps and hamstrings or other evidence of extensor mechanism misalignment<ref>Midtiby SL, Wedderkopp N, Larsen RT, Carlsen AF, Mavridis D, Shrier I. Effectiveness of interventions for treating apophysitis in children and adolescents: protocol for a systematic review and network meta-analysis. Chiropr Man Therap. 2018;26:41.</ref>.


Children and adolescents have growth zones in both the femur and the tibia and an apophysis (cartilage bone/cartilaginous material) at the tibial tuberosity. This cartilage (flexible connective tissue that often can be found between two bones), like bones, muscles and tendons, also has a grow capacity. But during the adolescent growth spurt, bones and cartilage grow much faster than muscles and tendons. The slower elongation of the musculotendinous extensor apparatus of the [http://www.physio-pedia.com/Knee knee]&nbsp;(m.[[Rectus Femoris|quadriceps]]) inflicts very strong forces on the small site of the insertion of the patellar tendon to the tibial tuberosity. These forces can cause microavulsions of the tibial tuberosity. The cartilage of the tibial tuberosity (the anterior portion of the developing ossification center of the tibial tuberosity) can resist forces but not as bone and when the child or the adolescent does some physical activities the forces at the the patellar tendon and tibial tuberosity increases, which causes pain, irritation and in some cases microavulsions or avulsions fractures of the tibial tuberosity.<ref name="two" />
Risk factors for the disorder are<ref>Watanabe H, Fujii M, Yoshimoto M, Abe H, Toda N, Higashiyama R, Takahira N. Pathogenic Factors Associated With Osgood-Schlatter Disease in Adolescent Male Soccer Players: A Prospective Cohort Study. Orthop J Sports Med. 2018 Aug;6(8):2325967118792192. </ref>:


Increased stress of the musculotendenous junction of the patellar tendon and tibial tuberosity can cause the tendon to pull away from the bone a little bit.&nbsp; This small amount of tearing leads to increased pain and swelling below the knee&nbsp;cap.&nbsp;The condition is worsened with activities that subject the patellar tendon to high loads such as [http://www.youtube.com/watch?v=UXJrBgI2RxA squatting], or jumping. In some cases ossification will occur at the area of trauma leading to a bony protuberance at the tibial tuberosity.

Pain is the leading symptom in this disease and it appears and aggravates during physical activities such as running, jumping, cycling, kneeling, walking up and down the stairs and kicking a ball(knee extension). In sports like basketball, volleyball, soccer, tennis, the pain increases. The clinical picture consists of pain localized to the area of the tibial tubercle. In some cases the tubercle may be swollen and hypertrophied and there is also tightness of the quadriceps muscle. Characteristics such as temperature or intra-articular swelling is not relevant (rarely the tuberosity can feel warm), but swelling, tenderness and pain of the tibial tuberosity often appears.

[[Image:Osgood-Schlatters.PNG|right|291x291px|alt=|frameless]]Radiological imagining is usually  not required, and is done in severe cases or if an avulsion is suspected.


X-Rays may be utilized to better visualize the musculotendenous junction in severe cases or if an avulsion is suspected.

*Radiographic examinations of both [http://www.physio-pedia.com/Knee knees] should always be performed, in both the anterior-posterior&nbsp;and lateral projections, to rule out the possibility of tumors, fractures, ruptures or infections. The lateral&nbsp;radiograph generally shows the characteristic picture of prominent tibial tubercle with irregularly ossific&nbsp;nucleus, or free bony fragment proximal to the tubercle. Imaging is also useful to exclude tuberosity&nbsp;epiphysiolysis or tumors.<ref>C Reid D. Sports injuries assessment and rehabilitation. Churchill Livingstone USA, 1992, p 406 – 411</ref>

*Sonographic examination can also be used. The [[Ultrasound Scans|ultrasound]] can be directed to demonstrate the&nbsp;appearance of the cartilage and bony surface, the patellar tendon, soft-tissue swelling anterior to the&nbsp;tibial tuberosity, and fragmentation of the tibial tuberosity. <br>

# Conservative treatment: Treatment should begin with rest, icing ([http://www.physio-pedia.com/RICE RICE]), activity modification and sometimes non-steroidal anti-inflammatory drugs.<ref name=":0" />
 
# Surgical treatment: Surgical procedures should be avoided until the child has grown up and the bone growth has been completed to avoid growth-plate arrest and the development of recurvatum and or valgus of the knee. Surgical treatment, we identified different surgical procedures such as drilling of the tibial tubercle, excision of the tibial tubercle (decreasing the size), longitudinal incision in the patellar tendon, excision of the ununited ossicle and free cartilaginous pieces (tibial sequestrectomy), insertion of bone pegs and/or a combination of any of these procedures. <ref name=":1" />

==== Pain Relief ====
 
* The pain usually subsides with the cessation of growth at the tibial tubercle.
The physiotherapist can focus on exercises to improve the flexibility and strenghten the surrounding musculature. This includes the [[Rectus Femoris|quadriceps]], [[Hamstrings|hamstring]], [[Iliotibial Band Syndrome|iliotibial band]] and the [[gastrocnemius]] muscle. High-intensity quadriceps-strengthening exercises increase stress across the tibial tuberosity and are initially avoided. Stretching should initially be performed statically at a low intensity to prevent pain before progressing to dynamic or PNF stretching. A duration of at least thirty seconds with three repetitions is recommended at least once a day to increase the range of motion. Low-intensity quadriceps-strengthening exercises, such as isometric multiple- angle quadriceps exercises, are therefore instituted earlier in the conditioning program. High-intensity quadriceps exercises and hamstring stretching are introduced gradually and have been proven effective with high evidence rating. (level of evidence: 1a)  <ref>Purushottam A.

Non-operative treatment of this disease is based on the same principles that apply all overuse injuries.

Of vital importance is that the physician inform the parents, the coach, and the child athlete of the natural course of this disease. The child should continue his normal physical activities, to the limit that the pain allows it, so lower intensity of frequency of exercising (activity modification). Also swimming, as a secondary athletic activity, is very good during this disease (no discomfort). Also knee-braces, tapes, slip-on knee support with an infrapatellar strap or pad are recommended and may help during physical activities and can reduce pain. (level of evidence: 5) <ref>C Reid D.

Introduction[edit | edit source]

Osgood-Schlatter Disease (OSD), or osteochondrosis, or tibial tubercle apophysitis, or traction apophysitis of the tibial tubercle, is a common cause of anterior knee pain in the skeletally immature athletic population. Clinically, it presents as atraumatic, insidious anterior knee pain, with tenderness at the patellar tendon insertion site at the tibial tuberosity.[1] The condition occurs secondary to repetitive extensor mechanism stress activities such as jumping and sprinting, as well as during sporting activities like Basketball, Volleyball, Sprinters, Gymnastic, Football.[1]

Overall treatment and management includes symptomatic treatment with ice and NSAIDs, activity modification and relative rest from aggravating activities, and lower extremities stretching regimen to alter underlying predisposing biomechanical factors.[1][2]

Etiology[edit | edit source]

Jumping.jpeg

OSD usually develops during the stage of bone maturation (10-12 yrs in girls and 12-14 yrs in boys) . The underlying etiology can be attributed to the repeated traction over the tubercle leading to microvascular tears, fractures, and inflammation; which then presents as swelling, pain, and tenderness.

OSD is an overuse injury that mostly appears in active, adolescent patients. The repetitive strain and microtrauma results in irritation and in severe cases partial avulsion of the tibial tubercle apophysis. Rarely trauma may lead to a full avulsion fracture. Predisposing factors include poor flexibility of quadriceps and hamstrings or other evidence of extensor mechanism misalignment[3].

Risk factors for the disorder are[4]:

  • Male gender
  • Ages: male 12-15, girls 8-12
  • Sudden skeletal growth
  • Repetitive activities like jumping and sprinting

Epidemiology[edit | edit source]

OSD is one of the most common causes of knee pain adolescent athletes.[1]

  • Usually occurs in adolescent growth spurts between ages 10 to 15 years for males and 8 to 13 years for females (11.4% in males, 8.3% in females)[5].
  • Is more common in males and athletes that participate in sports that involve running and jumping.
  • Symptoms present bilaterally in 20% to 30% of patients[6].

Relevant Anatomy[edit | edit source]

The tibial tubercle (the tuberosity of the tibia) is the protuberance along the anterior aspect of the tibia, just distal to the anterior surfaces of the medial and lateral tibial condyles. The tibial tubercle is entirely cartilaginous. It gives attachment to the patellar ligament or patellar tendon. The patellar tendon attaches to the tibial tuberosity inferior to the patella. Stress at this musculotendinous junction can cause pain and swelling.[7] The pain felt by the patient is mostly unilateral, but often it is bilateral.

OSD is localized at the tibial tubercle, distal and anterior to the knee.

Clinical Presentation and Examination[edit | edit source]

Anterior knee pain associated with or without swelling, is the leading symptom in this disease and it aggravates during physical activities such as running, jumping, cycling, kneeling, walking up and down the stairs and kicking a ball(knee extension) . The clinical picture consists of pain localized to the area of the tibial tubercle.

  • Painful palpation of the tibial tuberosity.
  • Pain at the tibial tuberosity that worsens with physical activity or sport.
  • Increased pain at the tibial tuberosity with sports activity.
  • In some cases increased bony protuberance at the tibial tuberosity.
  • Secondary to pain,Ely's test- there is tightness of Quadriceps.
  • Resisted isometrics of the Quadricep muscle is painful.[8]

Differential Diagnosis[edit | edit source]

Conditions that show similar presentation:

These diseases are also localized at the patellar tendon and can cause similar knee problems.

Diagnostic Procedures[edit | edit source]

Radiological imagining is usually not required, and is done in severe cases or if an avulsion is suspected.

  • The diagnosis is based on typical clinical findings (see clinical presentation). [10]
  • Radiographic examinations of both knees should always be performed, in both the anterior-posterior and lateral projections, to rule out the possibility of tumors, fractures, ruptures or infections. A picture of prominent tibial tubercle with soft tissue swelling, calcification of the patellar tendon, or free bony fragment proximal to the tubercle can be seen.
  • An utmost care must be taken, for accurate diagnosis, as sometimes the tibial protuberance may not be pathological. Therefore, clinical correlation must be done.

Prognosis[edit | edit source]

  • Excellent prognosis.[8]
  • The condition is self-limiting and hence recovers within a month
  • Sometimes the pain may persist up to 2 years, if unnoticed or left untreated.

Medical Management[edit | edit source]

  1. Conservative treatment: Treatment should begin with rest, icing (RICE), activity modification and sometimes non-steroidal anti-inflammatory drugs.[8]
  2. Surgical treatment: Surgical procedures should be avoided until the child has grown up and the bone growth has been completed to avoid growth-plate arrest and the development of recurvatum and or valgus of the knee. Surgical treatment, we identified different surgical procedures such as drilling of the tibial tubercle, excision of the tibial tubercle (decreasing the size), longitudinal incision in the patellar tendon, excision of the ununited ossicle and free cartilaginous pieces (tibial sequestrectomy), insertion of bone pegs and/or a combination of any of these procedures. [11]

Physical Therapy Management[edit | edit source]

Pain Relief[edit | edit source]

[12]

Exercise Therapy[edit | edit source]

Low-intensity Quadriceps-strengthening exercises, such as isometric multiple- angle quadriceps exercises, are therefore instituted earlier in the conditioning program. High-intensity Quadriceps exercises and Hamstring stretching are introduced gradually and have been proven effective with high evidence rating. [11] Incorporation of high-intensity Quadricep exercise can intensify pain.

[13]

Shockwave[edit | edit source]

Extracorporeal Shockwave therapy is a treatment which has been discussed in the use of OSD but due to the low value evidence recommendations cannot be made for this treatment. [14] 

Activity Limitation[edit | edit source]

Non-operative treatment of this disease is based on the same principles that apply all overuse injuries.

  • Today, there is no need for total immobilization, or for totally refraining from athletic activities.
  • Of vital importance is that the physician inform the parents, the coach, and the child athlete of the natural course of this disease.

The child should continue his normal physical activities, to the limit that the pain allows it, so lower intensity of frequency of exercising (activity modification). Also swimming, as a secondary athletic activity, is very good during this disease (no discomfort). Also knee-braces, tapes, slip-on knee support with an infrapatellar strap or pad are recommended and may help during physical activities and can reduce pain. [15] 

Research by Gerulis et al [16]has shown that limitation of physical activity, physical load restriction, and conservative treatment are more effective than physical load restriction and activity limitation alone.
