Autologous matrix-induced chondrogenesis (AMIC) has gained popularity in the treatment of osteochondral lesions of the talus. Previous studies have presented promising short-term results for AMIC talar osteochondral lesion repair, a 1-step technique using a collagen type I/III bilayer matrix. The aim of the present study was to investigate the mid-term effects. The 5-year results of a prospective cohort study are presented. All patients underwent an open AMIC procedure for a talar osteochondral lesion. Data analysis included general demographic data, preoperative magnetic resonance imaging findings, intraoperative details, and German version of the Foot Function Index (FFI-D) scores preoperatively and at 1 and 5 years after surgery. The primary outcome variable was the longitudinal effect of the procedure, and the influence of various variables on the outcome was tested. Of 47 consecutive patients, 21 (45%) were included. Of the 21 patients, 8 were female (38%) and 13 were male (62%), with a mean age of 37 ± 15 (range 15 to 62) years and a body mass index of 26 ± 5 (range 20 to 38) kg/m. The defect size was 1.4 ± 0.9 (range 0.2 to 4.0) cm. The FFI-D decreased significantly from preoperatively to 1 year postoperatively (56 ± 18 versus 33 ± 25; p = .003), with a further, nonsignificant decrease between the 1- and 5-year follow-up examination (33 ± 25 versus 24 ± 21; p = .457). Similar results were found for the FFI-D subscales of function and pain. The body mass index and lesion size showed a positive correlation with the preoperative FFI-D overall and subscale scores. These results showed a significant improvement in pain and function after the AMIC procedure, with a significant return to sports by the 5-year follow-up point. The greatest improvement overall was seen within the first year; however, further clinical satisfaction among the patients was noticeable after 5 years.
Background: The midline-incision trans-achillary approach (MITA) is frequently used for addressing all pathologies of insertional Achilles tendinopathy (IAT). The aim of this study was to assess the complication rate and possible influencing factors following a MITA for IAT treatment. Methods: Presented is a retrospective cohort study with current follow-up. Patients treated surgically by a MITA, addressing all pathologies of IAT, between January 2010 and October 2016 at a single reference center with at least 12 months of follow-up were included. General demographics (age, sex, and body mass index), medical history, surgical details (individual and sum of pathologies addressed), and duration of in-hospital stay were assessed. Patient satisfaction, shoe conflict, current employment status, time to return to sports, and type of sports were recorded using a custom questionnaire. Standard statistics, chi-square, and t tests were performed using SPSS. A total of 118 patients (follow-up, 63.4%) with a mean age (± SD) of 50 ± 12 years and a mean final follow-up time (± SD) of 4.2 ± 2.1 were included. Results: Fourteen percent of patients had a minor complication, the majority (75%) of which were surgical site infections. Forty-one percent were limited in their shoe selection, and 32% reported a shoe conflict. Seventy-eight percent were very satisfied, and 89% would recommend the surgery. Neither the individual surgical procedures, their sum, nor any other parameter showed a significant influence on the complication rate. The only factor negatively affecting patient satisfaction was a shoe conflict ( P < .001). Conclusion: The MITA for IAT treatment showed a moderate minor complication rate with good midterm patient satisfaction. However, the approach might predispose patients to shoe conflict, which negatively influences their satisfaction. Level of Evidence: Level IV, retrospective cohort study.
Background
The aim of this study was to review the patient rated outcome (PROM) of surgically treated fractures to the lateral process of the talus (LPTF) and identify factors influencing the outcome.
Methods
Retrospective study with a current follow-up. Eligible were all patients treated surgically for a LPTF (
n
= 23) with a minimum follow-up of one year. Demographics, medical history, trauma mechanism, fracture characteristics, concomitant injuries, treatment details, complications, return to work and sports were assessed retrospectively. The current follow-up included the VAS FA, Karlsson Score, and SF-12. The primary outcome was the VAS FA. Secondary aim was the identification of parameters influencing the PROMs.
Results
22 patients (96% follow-up) with a mean age of 32 ± 9 (18 to 49) years were included. 73% suffered a Hawkins Type 1, 23% a Type 2, and one patient a Type 3 fracture. 82% suffered concomitant injuries. 9% suffered minor surgical side infections, 50% developed symptomatic subtalar osteoarthritis. At final follow-up (44 ± 2 (12 to 97) months), the mean VAS FA Overall was 77 ± 21 (20 to 100), the Karlsson Score 72 ± 21 (34 to 97), and for the SF 12 the PCS 53 ± 8 (36 to 64) and the MCS 53 ± 7 (32 to 63). 50% of patients returned to their previous level of sports. Hawkins Type 1 fractures resulted in better VAS FA Overall score than Type 2 fractures. Posttraumatic subtalar osteoarthritis was the independent factor associated to a poor patient rated outcome (VAS FA, Karlsson Score).
Conclusion
After a follow-up of over 3.5 years, surgically treated LPTF resulted in only moderate results. 50% suffered posttraumatic symptomatic subtalar osteoarthritis, which was the primary independent parameter for a poor outcome following LPTF.
Level of evidence
Level III.

Between January 2009 and June 2013, a Dwyer osteotomy was performed in 31 patients with a mean age of 45.7 ± 16.3 years (range 21.5-77.4 years). All patients had a substantial inframalleolar cavovarus deformity with preoperative moment arm of the calcaneus of -17.9 ± 3.3 mm (range -22.5 to -10.5 mm), which has been improved significantly to 1.6 ± 5.9 mm (range -16.9 to 9.9 mm). Significant pain relief from 6.3 ± 1.9 (range 4-10) to 1.1 ± 1.1 (range 0-4) using the visual analogue scale was observed. The American Orthopaedic Foot and Ankle Society score significantly improved from 33.1 ± 14.2 (range 10-60) to 78.0 ± 10.5 (range 55-95).
