Hallux rigidus leads to significant loss of first metatarsophalangeal (MTP) joint motion. Cheilectomy surgery aims to increase motion, decrease pain, and facilitate a return to activity. Limited data exist regarding restoration of dynamic kinematics and loading responses following cheilectomy. This prospective study assessed three-dimensional in vivo first MTP joint kinematics and loading characteristics following cheilectomy.
Cheilectomy was effective in maintaining balanced plantar loading. First MTP motion increased but dorsiflexion was still less than normative values. The magnitude of dorsiflexion relative to abduction favorably improved during gait. These findings suggest that kinematics continue to be altered and may lead to further degenerative joint changes. Exploration of alternative surgical techniques is warranted.
