Innovation for the benefits of Patients and Healthcare Providers

High-Tibial-Osteotomy (HTO) is a surgical treatment option for patients suffering from knee arthritis but not yet suitable for partial or total knee-replacement. Current market solutions are surgically challenging, present several complications and can cause skin irritation due to the generic nature of the plate.

TOKA is a precision engineered personalised HTO solution to arthritic knee pain. It preserves the native joint by re-aligning the tibia and the weight / force distribution, often the major source of pain. TOKA simplifies the surgery by providing surgeons with an intuitive 3D planning environment to precisely achieve an optimised knee alignment with minimal risks for patients. Personalised implants may also provide better comfort and faster recovery.

TOKA HTO surgical combines 3D printing and data-imaging technologies for an individualised solution to knee osteoarthritis.

Personalised healthcare with additive manufacturing

A step change in personalised healthcare by integrating digital imaging and 3D printed (titanium sintered) implants based on the individual’s anatomy.

TOKA is ideal for the younger demographic, particularly those individuals with greater activity demands, allowing more intense use in athletics or high impact activities.

Structurally optimised stabilising plate for maximum patient comfort and recovery

Social Impact

Knee osteoarthritis is the most common musculoskeletal disease in the world. The knee surgery burden on the healthcare providers will only increase as the population lives longer and seeks to be more active meaning that cost-effective solutions are vital to treat patients and ensure their quality of life is maintained.

While knee replacement is the preferred treatment for older patients (over 65), the procedure is not always recommended for younger sufferers (40-65) as it has poorer clinical outcomes and escalating future revision costs.

High Tibial Osteotomy (HTO) is a treatment option for this younger group; preserving patient’s natural knees and restoring the correct alignment with the support of a stabilising plate.

With current HTO treatments, up to 24% of patients may go on to need a knee replacement at around 10 years following an osteotomy (Santoso et al., 2017, Journal of Orthopaedic Surgery and Research 12:50, Fu,et al., 2013, The Journal of Arthroplasty 28; 759–765) but for many it can be the definitive treatment.

TOKA is a revolutionary knee preserving surgical technique, relieving patients from pain and the societal impact of knee OsteoArthritis.
