Stickler Syndrome
What is Stickler syndrome?
Stickler syndrome is a hereditary connective tissue disorder caused by mutations in genes encoding collagen — most commonly COL2A1, COL11A1 or COL11A2 — that affect the structure and function of connective tissue throughout the body. It is one of the more common inherited connective tissue disorders, estimated to affect approximately one in 7,500 to 10,000 people, though it is significantly underdiagnosed due to its variable presentation and the wide range of specialists involved in its management.
The condition was first described by Dr Gunnar Stickler in 1965 and is now understood to encompass several subtypes with overlapping but distinct features depending on the specific gene mutation involved. What unites them is the fundamental disruption to collagen synthesis that affects joints, eyes, hearing, and facial structure — often in the same individual.
What are the features of Stickler syndrome?
Stickler syndrome is a multi-system condition and its features vary considerably between individuals and between subtypes. The most clinically significant are:
How is Stickler syndrome diagnosed?
Diagnosis is clinical and genetic. The combination of characteristic ocular findings, joint hypermobility, hearing loss and facial features in an individual and family history of similar features should prompt specialist evaluation. Ophthalmological assessment is often the initial diagnostic pathway, as the vitreous abnormality in type 1 Stickler is pathognomonic — it appears in a characteristic way that can be identified by an experienced ophthalmologist. Genetic testing confirming a pathogenic variant in one of the Stickler-associated collagen genes provides definitive diagnosis. The Stickler Involved People organisation is an excellent international resource for patients and families.
In Australia, Stickler syndrome patients are typically managed by a multidisciplinary team including ophthalmology, genetics, audiology, and — for the musculoskeletal component — physiotherapy and rheumatology.
How can physiotherapy help?
The physiotherapy management of Stickler syndrome focuses primarily on the musculoskeletal component — managing joint hypermobility, preventing injury, addressing joint pain, and maintaining function across the lifespan. The principles are similar to those applied in other connective tissue hypermobility disorders but need to account for the specific pattern of joint involvement and the progression toward early arthritis that characterises Stickler syndrome.
In children and adolescents, physiotherapy focuses on building the muscular stability needed to support hypermobile joints, developing proprioception and movement awareness, and managing the joint pain that can significantly affect school participation and physical activity. Early intervention is valuable — building good neuromuscular habits while the joints are still hypermobile is considerably easier than trying to address chronic pain and weakness that develops later.
As patients age and joint hypermobility transitions toward joint stiffness and early arthritis, the focus shifts to maintaining range of motion, managing pain, and protecting joint surfaces through appropriate load management and strengthening. Exercise physiology becomes increasingly relevant in this phase — structured exercise programs that build and maintain fitness while protecting vulnerable joints, and management of any associated metabolic or cardiovascular conditions.
For patients with scoliosis or significant spinal involvement, spinal stabilisation and postural management work is integrated into the overall program.
Clinical Pilates is particularly well suited to Stickler syndrome management — the low-impact, controlled environment of reformer-based exercise allows meaningful strengthening without the high joint loads of conventional gym training, and the emphasis on movement quality and body awareness addresses the proprioceptive deficits common in hypermobility conditions.
Our physiotherapist Yulia Khasyanova has specialist training in connective tissue disorders including Ehlers-Danlos Syndrome and related hypermobility conditions through the Ehlers-Danlos Society, and extensive experience in the complex musculoskeletal presentations that accompany systemic connective tissue disorders. She is one of a small number of physiotherapists in Brisbane with this level of specialist training. The Connective Tissue Disorders Network Australia provides support and resources for Australians living with Stickler syndrome and related conditions.
Hypermobility Connect Australia also offers peer support for patients navigating hypermobility-related conditions including Stickler syndrome.

What are the features of Stickler syndrome?
Stickler syndrome is a multi-system condition and its features vary considerably between individuals and between subtypes. The most clinically significant are:
- Joint hypermobility and musculoskeletal involvement — generalised joint hypermobility is a hallmark feature, often presenting in childhood with flexible joints, joint pain, and a tendency toward sprains and dislocations. As patients age, the hypermobility may reduce while joint pain and early-onset arthritis — particularly of the knees, hips and spine — becomes more prominent. Scoliosis and kyphosis are also seen, and mitral valve prolapse may co-occur given the systemic collagen involvement.
- Ocular involvement — the eye findings in Stickler syndrome are among the most serious features and require regular ophthalmological monitoring. High myopia (short-sightedness) is nearly universal in type 1 Stickler syndrome. Vitreoretinal abnormalities — particularly the characteristic optically empty or membranous vitreous — are present from birth. The risk of retinal detachment is significantly elevated and represents the most serious potential complication of the condition. Cataracts and glaucoma may also develop over time.
- Hearing — sensorineural hearing loss or mixed hearing loss is common in types 2 and 3 Stickler syndrome, typically mild to moderate and often progressive. Regular audiological assessment is recommended.
- Facial features — a characteristic facial appearance including midface hypoplasia (underdevelopment of the midface), a flattened nasal bridge, and sometimes cleft palate or Pierre Robin sequence (a combination of small jaw, cleft palate and tongue falling back in the throat) is seen in many patients, particularly those with type 1.
