“…Similarly to our patient, arthrofibrosis developed and was treated successfully with MUA. It is unclear whether NPS was the solitary cause for arthrofibrosis, however, because arthrofibrosis may also be correlated with computer navigation itself, as demonstrated in a meta-analysis by Ayekoloye et al 7 . Lachiewicz and Herndon performed a cemented, posterior-stabilized TKA in a patient with NPS 8 .…”

Case: Nail-patella syndrome (NPS) is a genetic disorder causing anatomical abnormalities about the knee, including significant patellar hypoplasia. We present a case of a patient with NPS and severe knee osteoarthritis undergoing computer-assisted total knee arthroplasty (TKA). Several intraoperative anatomical challenges were appreciated. Postoperatively, the patient developed arthrofibrosis requiring manipulation; however, his final outcome was favorable. Conclusion: Computer assistance may improve precision in patients with NPS undergoing TKA, but surgeons must be aware of the associated anatomic abnormalities and potentially increased risk of arthrofibrosis. Patellar resurfacing is often not feasible because of lack of bone stock.

“…These authors also mentioned that when computer navigation is used in TKR, 85% of the implanted knee replacements had ideal or very good alignment, compared with 55% in traditional TKRs without computer navigation [ 10 ]. A recent systematic review and meta-analysis also revealed that computer navigation-assisted knee replacement had improved outcomes when compared with conventional knee replacement, at mid-term follow-up [ 11 ].…”

Combined quadriceps tendon reconstruction and total knee replacement with computer navigation: a case report

et al. 2022

Background Chronic quadriceps tendon rupture is technically challenging for surgeons due to scarring and tendon retraction. The presence of concurrent ipsilateral knee osteoarthritis compounds the issue even further. Although a combined presentation is rare, treatment options to manage each coexisting pathology simultaneously are scarcely reported. We describe the case of a 67-year-old Caucasian male who had such a presentation, and was subsequently treated with a one-stage extensor mechanism autograft reconstruction and total knee replacement with computer navigation. Case The patient was a 67-year-old male Caucasian, who had previously sustained an acute rupture of his right quadriceps tendon that was adequately repaired 6 months prior. Despite an initial satisfactory result, he reported deterioration in his mobility in the few months thereafter, with worsening knee pain. His comorbidities consisted of hypertension, asthma, and a body mass index of 40.4 kg/m2. Otherwise, there were no risk factors for tendon rerupture. Clinical examination later revealed a large palpable gap in the right suprapatellar region and weakness of active knee extension. No traumatic cause for this new presentation was identified. Suspicion of a chronic quadriceps tendon rupture was confirmed on radiological imaging, but the investigations also noted the presence of severe tricompartmental osteoarthritis of the ipsilateral, native knee joint. The combined procedure took place in one surgical sitting. The total knee replacement with patella resurfacing was performed first and assisted by computer navigation. The quadriceps tendon reconstruction was then conducted sequentially using the patient’s hamstring tendons (semitendinosus and gracilis). The tensile strength was reinforced with use of a Ligament Augmentation and Reconstruction System (LARS) ligament. Initial outcomes were excellent, and these results were maintained at 6 months postoperatively, with the patient reporting no pain and having full range of movement. Conclusion Our techniques used have not previously been reported, but are successful options in treating coexisting chronic quadriceps tendon rupture and ipsilateral knee osteoarthritis. The advantage of using computer navigation with an extramedullary femoral jig can lead to improved accuracy of bone cuts, which is important in the presence of anatomical disruption. Chronic failures of the extensor mechanism require different approaches depending on the inherent and underlying pathology. We feel that the multidisciplinary team approach to the management and use of two surgeons with differing expertise added to the successful outcome of this complex case.

“…Nowadays, the literature still debated the navigated technique’s superiority in clinical and functional outcomes and life quality. Another recent systematic review and meta-analysis [ 25 ], published in 2020, reported a slight improvement in functional outcome using CAS, considering studies with 4 or 5 years of follow-up. The routine role of navigated TKA is still questioned by the costs, the additional operating time, the increased training, the potential for new and increased complications, and the lack of reproducible evidence [ 26 ].…”

Despite the globally ascertained success of Total Knee Arthroplasty (TKA) procedure, 20% of patients are still unsatisfied with the surgery results. The purpose of the study is to identify the functional and radiological outcomes of the computer-assisted (CAS) TKA compared to the conventional technique. The clinical databases and medical records of both clinical sites were retrospectively analyzed, and then according to study time-lapse, inclusion, and exclusion criteria, eligible patients were retrieved and included. A total of 42 patients that underwent to CAS TKA (NAVI) and 61 patients that underwent to Conventional TKA (CONV) were included. The NAVI group reported a statistically significant higher surgical time. A lower intraoperative blood loss was found in the computer-assisted group, though this difference was not statistically significant. Implant survival analysis at two years did not show differences between groups during the follow-up period. At two years, follow-up postoperative intergroup analysis showed no statistically significant difference between groups. According to the radiologic analysis, the NAVI group showed comparable outcomes to the conventional group. The present study showed that there was no clinical and radiological difference between CAS arthroplasty and conventional technique.
