“…There are limited data published for ToeFit-Plus prosthesis; most are based on retrospective reviews, whose results were compromised by small numbers and a short follow-up period (Table 2). 2,12,18,24,25,28,32,33,47 Despite the improved functional outcomes in these studies, high osteolysis and loosening rates have been encountered at the short and midterm follow-up. In 1 study of 23 patients, Daniilidis et al reported an increase in the average patient AOFAS-HMI score from 44 preoperatively to 82.5 at 18 months postoperatively.…”

“…Although several studies have reported the effectiveness of first MTP joint replacement for the treatment of hallux rigidus [10,22,23,27,30,32], there is little data available in the literature regarding evaluation and recommendations for sports participation after hallux rigidus surgery. It can be argued that, in our series, a longer follow-up is required in order to fully assess the clinical and radiological outcomes.…”

First metatarsophalangeal joint replacement is an alternative surgical procedure to arthrodesis in the treatment of moderate-to-severe hallux rigidus. However, few studies have been published about functional outcome after joint reconstructive procedures for hallux rigidus. The purpose of this study was to assess clinical, radiological and functional outcome, with special regard to recreational and sports activity, after first metatarsophalangeal joint replacement in patients affected by hallux rigidus grade III. Twenty-three patients who had undergone total joint replacement of the first metatarsophalangeal joint were examined preoperatively and three, six, 12 and 18 months postoperatively. All patients (mean age of 57.0±3.7 years) received a non-cemented TOEFIT-PLUS™ implant by one surgeon. Clinical scores (AOFAS score and VAS), radiological examination, patient satisfaction and sport participation were used to evaluate treatment outcome and radiolucent lines. The mean AOFAS score showed a significant improvement from 44.6±7.2 points preoperatively to an average of 82.5±14.4 points at last follow-up (p<0.001). The mean total ROM of the first MTP joint increased from 28.1±4.9 degrees preoperatively to 52.7±15.7 degrees postoperatively (p<0.001). After surgery, 91.3% of the patients were able to resume at least one recreational activity. Total arthroplasty for the treatment of hallux rigidus in an active patient population revealed good clinical and functional results. However, postoperative recreational sport activity showed a decrease in comparison to the pre-arthritic state. Further follow-up is necessary to quantify loosening risk in active patients after total hallux arthroplasty.

“…The only clinical observation is the too stiff artificial MTP1 joint, which causes pain during roll off and induces a negative effect on the affected bones due to relieving load transfer onto the outer foot and altered gait [12][13][14][15][16]. This risk can be minimized by means of precise surgical technique in accordance with the surgical instructions.…”

Background: Hemi-and total-replacement of the first metatarsophalangeal joint (MTP1) remains controversial due to failures observed in earlier decades. The TOEFIT-PLUS TM system was developed in part to address these earlier failures, but published reports investigating its use have been limited.Materials: The TOEFIT-PLUS TM MTP1 joint replacement system is designed with a self-tapping thread on a conical titanium core that provides cement-free, primary stable anchorage and focal pressure reduction in the corticocancellous bone due to an enlarged surface area. The modular design allows surgeons to decide intraoperatively whether to proceed with hemi-or total arthroplasty. Data from 3 studies are presented: 64 patients receiving total prostheses and followed-up annually (Seeber); 12 hemi-prostheses in 10 patients with 5.1 years average follow-up and 6 total prostheses in 5 patients with 1.5 years average follow-up (Knessl); and 54 prostheses (14 hemi-prostheses, 40 total prostheses) in 52 patients followed-up for an average of 3 years (multicenter study).Results: Seeber reported a 42.7-month service life of the prosthesis at the time of follow-up. Five patients (6.8%) were reoperated. Passive hallux motion was 15-18g reater than active motion, and patient satisfaction at follow-up was high. Knessl reported an average range of motion (ROM) in the sagittal plane of 55˚with an average dorsal extension of 25.3˚and plantar flexion of 30˚in patients who received hemi-prostheses. Prosthesis removal was necessary in 3 patients. Prosthesis loosening has not been observed. In patients undergoing total arthroplasty, ROM was recorded at 58˚. A revision operation was necessary in 1 patient. Revision surgery was necessary in 11 patients (21.1%) in the multicenter study. Patient-reported outcomes were favorable.Conclusion: The TOEFIT-PLUS TM joint replacement system offers improved implant stability and is able to handle high biomechanical loads and neutralize shear forces. When compared with other systems, it is associated with reduced osseointegration problems. Intensive postoperative strategies are recommended. Long-term follow-up studies are needed to further investigate the utility of this system.
