A Novel Technique to Treat Hallux Rigidus in Athletic Patients With Central Osteochondral Defects: Preliminary Report on 12 Cases.

Osteochondral defects, often caused by traumatic injuries, are focal areas of articular damage resulting in joint pain and stiffness ultimately leading to degenerative joint disease. This has not been well studied in the first metatarsal head, but is an often encountered problem in the active population in other joints. In this study, we prospectively evaluated the results of 12 patients who received autogenous bone grafting for repair of osteochondral defects of the first metatarsal head. Clinical outcomes were evaluated by the visual analog scale for pain and the Roles and Maudsley (RM) score. Between the years of 2009 and 2016, 12 patients received treatment for this particular surgical intervention and their outcomes were measured. The patients' average age was 43.5 ± 10.6 years and were followed from 52.3 ± 26.7 months postoperatively. Average return to activity was 4.7 ± 1.1 months. The average preoperative RM score was 4.0 ± 0.0 and postoperative RM score was 1.4 ± 0.7 (p = .0001). The encouraging outcomes of this study suggest that autogenous bone grafting for osteochondral defects of the first metatarsal head is an effective treatment to help restore the function of the first metatarsophalangeal joint.
