“The metallic implantation technique appears to be a promising treatment option for ODs of the medial talar dome after failed primary treatment”
“The clinical and radiologic results of 1-year follow-up are encouraging”

• Prospective case series of 15 patients with a clinical follow-up of 1 year.
• All patients had failed prior surgical treatment.• Median AOFAS improved from 69 (range, 42-75) to 87 (range,
58-100) (P = 0.001). • Pain improved from 56.6 ± 13.4 to 73.6 ± 22.1 (P = 0.001). • Function improved from 64.2 ± 13.0 to 82.8 ± 15.7 (P < 0.001). • Sports improved from 29.1 ± 19.6 to 48.3 ± 31.7 (P = 0.005). • QoL improved from 17.3 ± 13.9 to 46.3 ± 26.2 (P < 0.001).
“This prospective case report is the first clinical report of a metal implant for OCDs of the talus and gives an insight into the surgical technique and clinical follow-up. The metallic implantation technique appears to be a promising treatment for osteochondral defects of the medial talar dome after failed primary treatment.”

• 20 year old female with OCD• 2 previous arthroscopies on ankle• Followed for 2 years post implantation• Pain scores: walking improved from 8 to 0; running from
10 to 1• Foot and Ankle score improved on 4 of 5 subscales• RTS Korfball at 1 year• AOFAS improved to 90 at 2 years• Radiographs showed implant in position, no signs of
osteolysis or progression of degeneration

• 15 patients followed for 12.1+/- 1 months • Mean age 38 years (20-60 yrs)• Mean lesion size 15.7+/- 2.9mm x 10.9 +/- 1.8mm x 9.2 +/- 3.1mm• 13- Stage 3; 1- stage 3; 1 – unstaged• Pain at rest, walking, running and stair climbing improved sig. (p<0.05)• AOFAS, FAOS pain, function, sports, QOL improved sig. (p<0.05)• There were no signs of prosthetic loosening or progressive degenerative
changes on any of the postoperative radiographs
“focal resurfacing with a metallic implant appears to hold promise as a means to restore more quasi-physiologic contact mechanics in ankles with a large talar osteochondral defect, appreciably reducing biomechanical aberrations presumed to be responsible for whole-joint cartilage degeneration.”

Anderson et al 2010
• 7 cadaver ankles with created 15mm osteochondral defect • contact stresses measured before and after implantation• FEA for effect of implant height, post axis rotation and varus/valgus
tilt• Untreated defect: 20% reduction in contact area, 40% increase in
peak contact stress, shift in location• Resurfacing recovered 90% of contact area, same elevated contact
stress• 0.25 mm proud = 220% of peak contact stress in intact• Kinematics were restored
“our study shows that accurate and reproducible implantation of this novel metallic implant can be achieved, preventing excessive prosthetic pressure. The results suggest that the implant can be used clinically in a safe way, but the effectiveness and safety of this treatment option should be evaluated in a clinical study.”

• 12 patients prospective study followed for 2 years
• AOFAS scores improved from 70 (42-75) before surgery to 86 (58- 100) at 1 year, and 90 (87-90) at 2 years follow-up (p < 0.05)
• There were no clinical or radiographic complications.
