Background: Arthrodeses of hindfoot joints is commonly used to treat a multitude of painful conditions and deformity. Use of adjuvant low-intensity ultrasound bone stimulation has demonstrated promising results in the treatment of acute fractures and fracture nonunions. The purpose of this 12-month prospective study was to evaluate the healing rate and clinical results of patients undergoing primary subtalar arthrodeses with adjuvant low-intensity ultrasound bone stimulation. Materials and Methods: Fifteen consecutive patients participated in the study. Routine radiographs and CT scans were obtained, and clinical outcomes gathered. The clinical and radiographic data were compared to a similar cohort of patients previously reported on that had not received ultrasound bone stimulation. Results: The patients who received ultrasound bone stimulation showed a statistically significant faster healing rate on plain radiographs at 9 weeks ( p = 0.034) and CT scan at 12 weeks ( p = 0.017). A 100% fusion rate was noted. The American Orthopaedic Foot and Ankle Society (AOFAS) ankle and hindfoot score was also improved at 12 months postoperatively, a finding that was statistically significant ( p = 0.026). Conclusion: This is the first paper, to our knowledge, to prospectively evaluate ultrasound bone stimulation in primary hindfoot arthrodesis patients. We were able to show significantly improved radiographic as well as clinical outcomes compared with a similar cohort of patients who did not receive adjuvant ultrasound stimulation. We believe that low-intensity ultrasound bone stimulation is indicated in primary hindfoot fusions, particularly in those patients at higher risk for nonunion.

Background: Literature is sparse on whether severity of hallux valgus affects outcomes of surgery. We thus aimed to evaluate the impact of hallux valgus severity on the clinical outcomes of surgery. Methods: 83 consecutive scarf osteotomies performed by a single surgeon for symptomatic hallux valgus between 2007 and 2011 were divided into 3 groups (mild, moderate, and severe) based on severity of their preoperative hallux valgus using the hallux valgus and intermetatarsal angles. Outcomes were assessed using the visual analog scale (VAS) for pain, 36-Item Short Form Health Survey physical functioning (SFPF) and mental health (SFMH) subscales, and American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scores. These were assessed preoperatively and at 6 months and 2 years postoperatively. Patient satisfaction was assessed at 6 months and 2 years postoperatively. Eleven (13.2%), 54 (65.1%), and 18 (21.7%) feet were in the mild, moderate, and severe groups, respectively. Results: There was no difference in preoperative VAS, SFPF, SFMH and AOFAS scores between the groups except for AOFAS scores for the second toe, which were poorer with increasing hallux valgus. Postoperatively, there was improvement across all outcome scores. VAS and AOFAS showed excellent scores, and patient satisfaction was high across all 3 groups (88.9%, 89.4%, and 86.7%). The severe group had slightly lower SFPF scores at 6 months (mild, 81.1; moderate, 84.0; severe, 74.3; P = .031) and 2 years postoperatively (mild, 93.4; moderate, 89.7; severe, 76.4; P = .005), and slightly poorer second toe scores for VAS (mild, 0.0; moderate, 0.1; severe, 1.2; P = .017) and AOFAS (mild, 94.7; moderate, 93.5; severe, 83.4; P = .043) at 2 years postoperatively. All other scores including patient satisfaction showed no between-group differences. Complication and revision rates between the groups were similar. Conclusion: Surgery for symptomatic hallux valgus lead to excellent outcomes and high patient satisfaction regardless of severity of deformity. Level of Evidence: Level III, comparative series.

Osteochondral Autologous Transplantation

Background: Plug protuberance occasionally occurs in osteochondral autologous transplantation (OAT). The incongruity of plugs results in poor clinical outcomes, especially in cases of protuberance. However, a surgical procedure to deal with this problem has not been reported. Purpose/Hypothesis: The purpose was to evaluate the efficacy and safety of cartilage resection of elevated plugs, with the hypothesis that patients whose elevated plugs were resected and leveled would achieve clinical outcomes equivalent to those of patients with flush plugs. Study Design: Cohort study; Level of evidence, 3. Methods: Cases (group P) included 22 patients who underwent OAT of the knee and whose plugs showed protuberance greater than 1 mm that was resected with a scalpel to obtain smooth congruity, while controls (group C) included 22 background-matched patients who did not require plug resection. The International Knee Documentation Committee (IKDC) subjective score, IKDC objective grade, and Japanese Orthopaedic Association score for knee osteoarthritis (JOA knee score) were used preoperatively and at the final follow-up (mean ± SD, 49.3 ± 18.1 months). International Cartilage Repair Society (ICRS) Cartilage Repair Assessment was used to evaluate lesion healing during the second-look arthroscopy. Results: IKDC subjective scores of group C (82.5 ± 11.8) and group P (82.1± 15.1) showed no difference at the final follow-up. On postoperative IKDC objective grading, 86% of group C and 82% of group P patients were graded as “nearly normal” or better ( P = .639). The mean JOA knee scores of group C (90.9 ± 8.9) and group P (90.1 ± 9.5) did not differ significantly ( P = .647). Nine second-look arthroscopies were performed in group C versus 8 in group P, and all patients had plugs that were graded as “nearly normal” or better by the ICRS Cartilage Repair Assessment. Larger plugs tended to be used in those patients who required resection. Conclusion: Resection of the elevated plug surface did not negatively affect patient outcomes in the midterm follow-up period.
