        Treatment of Isolated Ankle Osteoarthritis with Arthrodesis or the Total Ankle Replacement: A Comparison of Early Outcomes

        Charles L. Saltzman,,Robert G. Kadoko, MD,서진수 대한정형외과학회 2010 Clinics in Orthopedic Surgery Vol.2 No.1

        Background: Ankle arthrodesis and replacement are two common surgical treatment options for end-stage ankle osteoarthritis. However, the relative value of these alternative procedures is not well defi ned. This study compared the clinical and radiographicoutcomes as well as the early perioperative complications of the two procedures. Methods: Between January 2, 1998 and May 31, 2002, 138 patients were treated with ankle fusion or replacements. Seventy onepatients had isolated posttraumatic or primary ankle arthritis. However, patients with infl ammatory arthritis, neuropathic arthritis,concomitant hind foot fusion, revision procedures and two component system ankle replacement were excluded. Among them,one group of 42 patients had a total ankle replacement (TAR), whereas the other group of 29 patients underwent ankle fusion. A complete follow-up could be performed on 89% (37/42) and 73% (23/29) of the TAR and ankle fusion group, respectively. Themean follow-up period was 4.2 years (range, 2.2 to 5.9 years). Results: The outcomes of both groups were compared using a student’s t-test. Only the short form heath survery mental componentsummary score and Ankle Osteoarthritis Scale pain scale showed significantly better outcomes in the TAR group (p < 0.05). In theradiographic evaluation, there was no signifi cant difference in preoperative and postoperative osteoarthritis between the TAR and fusiongroups. Conclusions: The clinical results of TAR are similar to those of fusion at an average follow-up of 4 years. However, thearthroplasty group showed better pain relief and more postoperative complications that required surgery.

        족관절 인공관절 치환술 후 족관절 운동범위의 변화

        서진수,Suh, Jin-Soo,Saltzman, Charles L. 대한족부족관절학회 2006 대한족부족관절학회지 Vol.10 No.1

        Purpose: Ankle fusion that is operated on severe ankle arthritis has its weakness in that normal walking is impossible, even though the result is pretty good. As a alternative choice, total ankle replacement pursues the longer survivorship with material improvement. However, it is not yet known how much range of motion is possible after the replacement, or how it has changed overtime. Therefore, we need an analyzation for that. Materials and Methods: A retrospective review of sixty-seven patients undergoing STAR total ankle replacement at our institution between 1998 and 2002 was conducted. Of those, twenty-six (39%) had complete sets of full dorsiflexion and plantar flexion lateral radiographs both between "immediate" postop and at a minimum of 2-years follow-up and no revision procedure during that time. The mean age of these patients was 63.2 years when the surgery was done; the etiology of arthrosis was 21(81%) post-traumatic/degenerative, 4 rheumatoid and 1 psoriatic. Results: Average "immediate" ankle range of motion was $15.9^{\circ}$, and total foot (non-ankle) motion was $20.6^{\circ}$. At one, two, and three years the average ankle and total foot ranges of motion were $17.4^{\circ}$, $17.6^{\circ}$, $15.6^{\circ}$ and $21.0^{\circ}$, $22.0^{\circ}$, $21.2^{\circ}$ respectively. Statistically there was no significant difference between "immediate" postop motion and one to three years postop (all p>0.05). Conclusion: The range of motion after the STAR total ankle replacement is maintained from the "immediate" postoperative range of motion, but not increased, in the 1-3 year post replacement period.
