“…OPTY-LINE patients need to undergo the daily elongation procedure for up to 6 weeks after surgery, whereas Tomofix patients have effectively completed their correction once off the operating table. Since a lot of patients do not return to playing sports after more than 6 months following HTO, 4,5,9 the potential impact of OPTY-LINE on return to physical activity was not assessed in detail in this proof of concept study due to the limited follow-up period. Nonetheless, both OPTY-LINE and Tomofix patients achieved an MPCI at 6 months in terms of KOOS sports sub-score.…”

“…3 Tomofix patients tend to resume normal activities of living soon after surgery with work-related physical activities introduced at 3-4 months and sports after approximately 6-12 months. 4,5 One reservation for allowing patients to fully weight bear early on is the perceived risk of loss of correction of the angle, although in practice this effect appears to be a rare occurrence. 1,6,7 Histologically, there is variability in the degree of healing and indeed maturation of bone regeneration achieved in the open wedge.…”

Purpose: The objective was to evaluate the clinical and patient-related short- to medium-term performance of the OPTY-LINE nail device for high tibial osteotomy (HTO), comparing a case series of the said device to the established Tomofix fixed-plate device. Patients and Methods: Males with symptomatic medial compartmental osteoarthritis and no serious (co-morbid) knee pathology were followed up, five Tomofix and six OPTY-LINE patients. Patients underwent computed tomography assessment and completed Knee Injury and Osteoarthritis Outcome score (KOOS) and osteotomy surgery patient satisfaction questionnaires, 3 and 6 months post-surgery. A radiologist impression score and a quantitative digital bone density analysis were performed by two independent radiologists. Mann–Whitney U test was applied for inferential statistical tests. Results: At 6 months post-surgery, for Tomofix, the median radiologists’ healing impression score was ‘progressive healing’ versus ‘union virtually complete’ for the OPTY-LINE nail; bone healing quotient was 1.30 (standard deviation (SD) 1.74) versus 1.78 (SD 1.58), p = 0.18. The post-operative absolute surgical accuracy was a mean 12 (7.5) for Tomofix versus 4.1 (2.3) for OPTY-LINE, p = 0.052. At baseline, however, Tomofix patients had more knee symptoms, as determined by KOOS symptom sub-score, when compared to the OPTY-LINE cohort ( p = 0.009). Conclusion: This initial, non-randomized, comparative evaluation of the OPTY-LINE device for HTO has produced similar outcomes to patients treated with the established Tomofix device. In particular, the rate of post-surgical bone regeneration and surgical accuracy achieved with the OPTY-LINE device are encouraging. Large-scale randomized controlled studies with longer follow-up are indicated to further evaluate the clinical and patient-related outcome performance for OPTY-LINE.

“…Of note is the strong improvement in sport & recreation scores recorded by both OPTY-LINE and Tomofix patients. In the initial short-term follow-up study of OPTY-LINE this could not be appraised, since patients tend to wait a number of months before returning to more strenuous activities such as sports [22,23]. However, since HTO patients can be younger than knee replacement patients and are usually still physically active, both OPTY-LINE and Tomofix are suitable candidate medical devices to treat osteoarthritis of the knee.…”
