Osteoarthritis in Young People
Original Editor - Anna Jansma
Osteoarthritis in young people has two components: osteoarthritis, which means inflammation (itis) of the joint (arthro) and bones (osteo); the second component, namely young people is harder to define because young is a relative conception.
There are two main classifications of OA
- Primary osteoarthritis: is the form where you don't know what could have triggered the disease, inferring history or clinical/radiographic examination.
- Secondary osteoarthritis: can be caused by trauma, metabolic disease, congenital malformations, premature menopause, etc. Developmental dysplasia of the hip (DDH) is one of the most common causes of secondary osteoarthritis in young adults
The etiology of osteoarthritis is multifactorial, so it could be determined and/or developed by several risk factors including:
- Psychological and socio-economical factors
- Sedentary lifestyle
- Biomechanical factors: malalignment, joint laxity, muscle weakness or reduced proprioception
- Metabolic, and inflammatory processes: elevated levels of C-reactive protein, elevated levels of hyaluronic acid and atrophy of the bone
- Overweight: Obesity in children and adolescents has been linked to musculoskeletal disorders, therefore, excess force or joint loading may lead to osteoarthritis in overweight teens.
- Sports participation/occupation: High-impact, high-intensity, and repetitive athletics have a strong association with OA.
Power and team sports such as soccer, basketball, track and field, boxing, wrestling and weight lifting have been linked with the development of early-onset OA. These risk factors may lead to the development of premature osteoarthritis in a genetically susceptible person.
- Female gender
- African American race
- Comorbidity (heart/lung, diabetes, articular disorders, poor vision, etc)
- Genetic predisposition: more than 50% of all cases of OA result from a hereditary disposition. The interleukin-1 gene cluster, a key regulator in several chronic disease processes, conferred a twofold risk of OA in those with a specific genotype. These findings support that OA is not just a disease of the older people.
Nonspecific symptoms, mainly local:
- Loss in ROM
- Stiffness / total blocking
- Morphological deformities
Pain is more likely caused by congenital hip dysplasia, athletic injuries, trauma, spondyloarthropathy, and by conditions that first appear during this stage of life, such as rheumatoid arthritis, osteoarthritis, intravenous drug use, alcoholism, or corticosteroid use.
Furthermore the more common characteristics of generalized osteoarthritis can be found in the young adult, mainly in the Hip and Knee.
The diagnostic procedures for young people suffering from osteoarthritis is not different from people who are older. There are guidelines for diagnosis of different types of osteoarthritis, like hip and knee osteoarthritis. Main focus in both (and thus also in young patients) is the evolution of pain. The diagnosis itself is confirmed by radiography.
Oftenly used tests to quantify “body function, activity and participation” are:
In young subjects, however, some of these tests should be adjusted for the age: difficult terminology should be avoided in questionnaires, score outcomes should be compared with subjects of the same age and exercise difficulty should be appropriate for the subject.
The examination should evaluate the patient’s functional performance. The examiner should:
- Inspect posture and movement in daily activities, with special attention for the back, pelvis, ankles and feet. If walking aids are used, the upper extremity must also be inspected.
- Palpate for presence of swelling or raised temperature and muscle tone.
- Do active/passive functional testing
- Assess muscle strength
- Assess mobility
- Assess balance and stability
- Assess coordination
For patients with osteoarthritis, there is a variety of options for surgery. For young patient especially there is a special technique which focusses on the level of activity after surgery. Autologous Chondrocyte Implantation is used for joint preservation. The chondrocytes are said to produce hyaline-like repair tissue. Early reports suggest that this procedure reduces symptoms and increases functions. Furthermore, more and more young patients are undergoing a total arthroplasty of hip or knee
Physical Therapy Management
Physical therapy for young people suffering from osteoarthritis is still a novelty. There are indications that physical therapy for hip osteoarthritis consisting of muscle strengthening, muscle stretching and neuromuscular control exercises have positive results
This is in agreement with another finding that says that the following physiotherapy techniques are valuable therapeutic adjuvants for the treatment of osteoarthritic symptoms.
- Muscle relaxing action
- Hot or cold application on osteoarthritic joint
- Proprioceptive reeducation
- TENS: may be beneficial to patient with knee OA)
- Range of motion exercises
- Strengthening exercises
- Stretching exercises
- Massage: Following KNGF-guidelines massage has lost its place to exercises, which should be the cornerstones in all therapy for OA.
- Hydrotherapy and Spa Treatment
The goal of the differential diagnosis of hip pain is to identify the location and underlying mechanism of the pain. An accurate history and physical examination may indicate whether the pain is intra-articular, extra-articular, or referred from more distal locations. Additional laboratory or imaging tests may be necessary to determine the exact cause. Fractures, infection, and ischemic necrosis should be ruled out early because they require immediate treatment to prevent damage to the joint.
The prevention of development of osteoarthritis in the adolescent can be achieved by reducing risk factors. Physiotherapists can promote the maintenance of a healthy weight, low-impact activities, giving exercises to improve joint stability to prevent joint injuries. They can have influence by preventing further progression or complications of a disorder and improving the patient’s self-efficacy.
In case of malalignments (leg-length discrepancy, varus/valgus, etc.) young patients should be referred to a podiatrist for insoles to prevent the development of OA (in the hip or knee) at an older age.
