Purpose:
to describe an original technique and preliminary results of bipolar fresh osteochondral allograft implantation for the treatment of end-stage glenohumeral osteoarthritis.
Methods:
three patients underwent bipolar fresh osteochondral allograft implantation to the shoulder. Clinical and radiographical evaluations were carried out periodically through to final follow-up.
Results:
constant Score increased from 38.3 ± 2.9 pre-operatively to 78.7 ± 16.2 at 12 months, 72.3 ±15.3 at 24 months, and 59.3 ± 22.0 at 34 months. Arthritis and partial reabsorption of the implanted surfaces were evident radiographically.
Conclusions:
the clinical results obtained in these patients seem to support the applicability of bipolar fresh osteochondral allograft implantation in the shoulder in subjects with severe post-traumatic arthritis and intact rotator cuff. The development of arthritis of the implanted surfaces, while not impacting the clinical result, is a cause of concern.
Level Of Evidence:
level IV, therapeutic case series.
