Navigated, soft tissue-guided total knee arthroplasty restores the distal femoral joint line orientation in a modified mechanically aligned technique

Abstract: PurposeTo investigate the femoral component alignment in patients undergoing soft tissue‐guided, navigated total knee arthroplasty (TKA). It was hypothesized that with a mechanically aligned tibial component, the soft tissues tensioned and symmetric medial and lateral gaps in flexion/extension, the femoral component would be aligned to the preoperative distal femoral joint line, as measured on knee radiographs. MethodsBetween 2015 and 2017, 77 patients (78 knees) underwent navigated soft tissue‐guided TKA at a… Show more

“…A cadaveric study demonstrated that a joint line change of > 2 mm was associated with a decreased flexion angle [11]. Furthermore, joint line elevation reportedly causes patella baja, resulting in poor clinical outcomes [40, 41]. Therefore, TKA with MST was introduced to minimise medial soft tissue release and to allow residual lateral laxity.…”

“…Recently, favorable or improved functional outcomes through individualized alteration of alignments. 49,50 However, this issue should be reevaluated and the necessity of RV alignment should be reconsidered in the future, based on studies with higher levels of evidence on longevity of the prosthesis and functional benefits of the procedure.…”

“…In cases in which distal femoral landmarks have been altered or removed, techniques using navigation and soft-tissue balancing have been described 66,67 . In these techniques, the tibial cut is first made 90° to the mechanical axis and navigation is used to balance and restore the distal femoral joint line 67 . Although patellar height is less reliably restored, this may be assessed clinically or radiographically intraoperatively, and distal femoral augments, tibial tubercle osteotomy, or quadricepsplasty can be used to adjust accordingly 66 .…”

“…Specific UKA implants and UKA modes of failure can determine the degree of surgical complexity; a modular step-cut UKA implant is the most complex implant to convert, and tibial fracture is the most complex failure mode to address 63 .

In these techniques, the tibial cut is first made 90° to the mechanical axis and navigation is used to balance and restore the distal femoral joint line 67 .…”
