PUBLISHED RESEARCH

Peer-reviewed papers

Limanou GR, Lim PQX, Lithgow MJ, Buldt AK, Munteanu SE, Menz HB. Foot shape in women with and without hallux valgus determined using 3-dimensional foot scanning. Journal of Foot and Ankle Research, 2026.

In short: compared with women of the same age without bunions, women with hallux valgus had wider feet at the forefoot and heel, and a larger, taller ball of the foot, which matters for how shoes fit.

Lithgow MJ, Maharaj JN, Buldt AK, Munteanu SE, Mentiplay BF, Menz HB. Lower limb kinematics of people with midfoot osteoarthritis during level walking and stair climbing. Journal of Foot and Ankle Research, 2025.

In short: compares how the hips, knees, ankles and feet move during walking and stair climbing in people with and without midfoot arthritis, using 3D motion analysis.

Lim PQX, Menz HB, Landorf KB, Kaminski MR, Buldt AK, Lithgow MJ, Paterson KL, Halstead J, Munteanu SE. Efficacy of arch contouring foot orthoses for midfoot osteoarthritis: protocol for a randomised controlled trial. Journal of Foot and Ankle Research, 2024.

In short: sets out a trial in 140 people with painful midfoot arthritis, comparing arch-contouring orthotics with flat sham insoles over 12 weeks.

​

Munteanu SE, Buldt AK, Lithgow MJ, Cotchett M, Landorf KB, Menz HB. Non-surgical interventions for treating osteoarthritis of the big toe joint. Cochrane Database of Systematic Reviews, 2024.

In short: brings together the clinical trials of non-surgical treatments for arthritis of the big toe joint, such as injections, orthotics and shoe-stiffening inserts.

Lithgow MJ, Buldt AK, Munteanu SE, Marshall M, Thomas MJ, Peat G, Roddy E, Menz HB. Plantar pressures in people with midfoot osteoarthritis: cross-sectional findings from the Clinical Assessment Study of the Foot. Gait & Posture, 2024.

In short: people with midfoot arthritis put more force and pressure through the middle of the foot when walking, which fits with having a lower arch.

Lithgow MJ, Buldt AK, Munteanu SE, Marshall M, Thomas MJ, Peat G, Roddy E, Menz HB. Structural foot characteristics in people with midfoot osteoarthritis: cross-sectional findings from the Clinical Assessment Study of the Foot. Arthritis Care & Research, 2024 (published online 2023).

In short: on x-ray, people with midfoot arthritis had a flatter foot posture than people without it.

Lim PQX, Lithgow MJ, Kaminski MR, Landorf KB, Menz HB, Munteanu SE. Efficacy of non-surgical interventions for midfoot osteoarthritis: a systematic review. Rheumatology International, 2023.

In short: orthotics, shoe-stiffening inserts and steroid injections may help midfoot arthritis in the short term, but the trials so far are small and of low quality.

​

Lithgow MJ, Munteanu SE, Buldt AK, Arnold JB, Kelly LA, Menz HB. Foot structure and lower limb function in individuals with midfoot osteoarthritis: a systematic review. Osteoarthritis and Cartilage, 2020.

In short: across earlier studies, people with midfoot arthritis tended to have flatter, more mobile feet and higher pressures under the foot when walking.
