This study describes the Osseointegration Group of Australia’s
Accelerated Protocol two-stage strategy (OGAAP-1) for the osseointegrated
reconstruction of amputated limbs. We report clinical outcomes in 50 unilateral trans-femoral amputees
with a mean age of 49.4 years (24 to 73), with a minimum one-year
follow-up. Outcome measures included the Questionnaire for persons
with a Trans-Femoral Amputation, the health assessment questionnaire
Short-Form-36 Health Survey, the Amputation Mobility Predictor scores
presented as K-levels, 6 Minute Walk Test and timed up and go tests.
Adverse events included soft-tissue problems, infection, fractures
and failure of the implant.Aims
Patients and Methods
The treatment of osteochondral lesions of the talus has evolved with the development of improved imaging and arthroscopic techniques. However, the outcome of treatment for large cystic type-V lesions is poor, using conventional grafting, debridement or microfracture techniques. This retrospective study examined the outcomes of 50 patients with a cystic talar defect who were treated with arthroscopically harvested, cored osteochondral graft taken from the ipsilateral knee. Of the 50 patients, 45 (90%) had a mean good to excellent score of 80.3 (52 to 90) in the Karlsson-Peterson Ankle Score, at a mean follow-up of 36 months (24 to 83). A malleolar osteotomy for exposure was needed in 26 patients and there were no malleolar mal- or nonunions. One patient had symptoms at the donor site three months after surgery; these resolved after arthroscopic release of scar tissue. This technique is demanding with or without a malleolar osteotomy, but if properly performed has a high likelihood of success.
