“…Following arthrodesis of the MTP joint, metatarsalgia was reported in 23%, 13 following silicone hemiarthoplasty in 25% of patients. 37 Pedobarographic assessment demonstrated a decrease of maximum pressure, force and contact area under the great toe. This decrease in pedobarographic function was surprisingly moderate.…”

Background: We assessed the long-term results following Keller resection arthroplasty for the treatment of hallux rigidus. We then compared them with alternative surgical methods like cheilectomy, arthrodesis and joint replacement. Methods: Eighty-seven cases of Keller resection arthroplasty for hallux rigidus were reviewed with mean followup of 23 years. Their mean age at time of surgery was 50 years. Analysis included personal clinical evaluation with the AOFAS Hallux Score, quality-of-life assessment using the SF-36, radiographic assessment, pedobarographic evaluation and analysis of the patients' charts to detect any postoperative complications. Results: At the time of followup only five (5%) feet had undergone revision surgery. For all other cases we calculated a mean AOFAS score of 83 points. Sixty-nine of 73 unrevised patients (94%) would opt for this operation again under the same circumstances. SF-36 parameters showed age related normal values. Pedobarographic assessment revealed only moderate weightbearing alterations. Our long-term results compare favorably with published results following arthrodesis, cheilectomy or joint replacement for the treatment of painful hallux rigidus. Clinical results and subjective assessments were very good and complication rates were low compared to competing methods. Conclusion: Keller resection arthroplasty remains a valuable surgical option for the treatment of advanced stages of hallux rigidus with high patient satisfaction, moderate weightbearing alterations and comparable low complication rate in our experience.

“…This precipitates a synovitic process within the joint [19] that ultimately leads to fragmentation of the prosthesis and periimplant osteolysis. When this eminently predictable process occurs, patients represent to clinic complaining of pain at the site of the arthroplasty [20,21].…”

“…In studies to evaluate the results of these prostheses (Silastic ® ), we found wide variability in the conclusions, ranging from long-term success (13,14) to early failure. Shankar (5) , in 1995, presented a trial involving 40 patients with an average follow-up period of 110 months, in which the complication rate was 36%, mainly due to fragmentation of the silicone. A high incidence of granulomatous reactions to silicone particles is also reported in about 72% of patients, and causes significant osteolysis (6,7) .…”

“…In 1979, Swanson proposed the use of the interposition silicone prosthesis (Silastic ® ) (4) . However, these prostheses presented several complications, including fracture of the prosthesis and synovitis and bone lysis related to worn particles of silicone (5)(6)(7) . In 1994, the use of zirconium ceramic components (Moje ® ) was tested, but these materials also presented several complications, particularly due to fracture of the material (2,8,and 9) .…”
