Arthrofibrosis is a known complication of
hallux valgus surgery. Joint manipulation under
anesthesia has been studied for
adhesive capsulitis of the shoulder; however, a paucity of published data exists on the use of this modality in the foot and ankle. The purpose of the present study was to investigate the outcomes of first metatarsophalangeal joint manipulation for arthrofibrosis that occurred as a complication of
bunion surgery. The study population consisted of patients attending a single foot and ankle specialty clinic who were evaluated for arthrofibrosis after
bunion surgery. Patients who underwent joint manipulation under
anesthesia were asked to complete a research visit in which a clinical examination was performed and the presence and severity of
joint pain were assessed. A total of 38 patients (34 females, 4 males, 53 feet), with a mean age of 55.7 ± 11.8 (range 30 to 83) years, agreed to participate. The mean follow-up period was 6.5 ± 3.4 (range 1 to 17) years. The visual analog scale scores improved significantly from baseline to the final follow-up visit (baseline 6.5 ± 1.5, range 2 to 10; final follow-up visit 2.3 ± 1.5, range 0 to 6; p < .001). Furthermore, joint motion had increased significantly (p < .001) for both dorsiflexion and plantarflexion at the final follow-up examination. The final range of motion (dorsiflexion, r = -0.431, p = .002; plantarflexion, r = -0.494, p < .001) correlated highly with patient self-reported
pain in the first metatarsophalangeal joint. Our findings suggest that joint manipulation could be a useful modality for increasing first metatarsophalangeal joint mobility and alleviating
pain in patients who experience arthrofibrosis after surgical correction of
hallux valgus.
