“…In the past few decades, many surgeons have been reluctant to use PFA due to its high failure and revision percentages. However, the most common causes of revision for these patellofemoral implants reported in past studies were progression of tibiofemoral OA and prosthetic problems, which accounted for more than 50% of the revision after 15 years of follow-up [ 23 – 25 ]. Some authors further reported that tibiofemoral OA progression is more frequent in obese patients and when the indication is primary PFOA than in those affected by trochlear dysplasia [ 26 , 27 ].…”

Background We aimed to compare second-generation patellofemoral arthroplasty (2G PFA) with total knee arthroplasty (TKA) in treating isolated patellofemoral osteoarthritis (PFOA) by assessing the percentages of revisions, complications, and patient-reported outcome measures (PROMs). Methods Studies that compared the outcomes of 2G PFA and TKA in the treatment of isolated PFOA were searched in electronic databases, including MEDLINE, Embase, and Web of Science. Two researchers independently identified eligible studies, extracted the data, and evaluated the quality of the literature. Pooled risk ratios (RRs) or weighted mean differences with 95% confidence intervals were calculated using either fixed or random effects models. Descriptive analysis was used when data could not be pooled. Results A total of six studies were included in the review. For the revision percentage and complications, there were no significant differences between 2G PFA and TKA (RR = 2.29, 95% CI 0.69–7.58, P = 0.17; RR = 0.56, 95% CI 0.23–1.40, P = 0.22, respectively). Second, the results demonstrated that the differences in the Oxford Knee Score (OKS) and the University of California, Los Angeles (UCLA) activity score between 2G PFA and TKA were not significant (WMD −4.68, 95% CI −16.32 to 6.97, p = 0.43; WMD 0.16, 95% CI −1.21 to 1.53, P = 0.82). The Knee Injury and Osteoarthritis Outcome Score (KOOS), the American Knee Society Score (AKSS), and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) were presented in a narrative form due to methodological heterogeneity. Conclusion For isolated PFOA, 2G PFA demonstrated similar results to TKA with respect to the percentages of revisions, complications, and PROMs.

“…Knee joint, the main load-bearing joint of human lower limbs, plays an important role in transmitting the strength of lower limbs, maintaining flexibility and stability in human daily activities [18]. PCL, as one of the most important ligaments of the knee, has the main function of restricting the posterior tibial displacement and enhancing the stability of the knee joint, as well as limiting tibial rotation, knee joint overextension and adduction (2).…”

Background This prospective study was to analyze the clinical effect of double-stranded long peroneal tendon and the four strands hamstring tendon in reconstruction of posterior cruciate ligament (PCL), and to investigate the effectiveness and safety of the two surgical approaches in reconstruction of PCL, so as to provide guidance for clinical treatment of PCL injury. Methods Total 48 patients with complete rupture of PCL treated in our hospital from July 2015 to February 2017 were selected and divided into the Group A (reconstructed with double strands peroneus longus tendon, 25 cases) and the Group B (four strands hamstring tendon, 23 cases) according to the different grafts. Results The intraoperative time for tendon extraction in the Group A (20.87 ± 2.07 min) was significantly shorter than that in the Group B (26.79 ± 2.32 min). Compared with pre-operation, the tibial posterior displacement of the two groups decreased significantly 24 months after operation, and IKDC score, Lysholm score and Tegner score increased significantly. Nevertheless, the IKDC score, Lysholm score, Tegner score, AOFAS score and Maryland score between the two groups before and after operation were no significant differences. Compared with the quadrupled hamstring tendon, the double-stranded peroneal longus tendon has the advantages of simple and safe tendon extraction. Conclusions Both surgical methods are effective for the treatment of PCL injury. When the four strands hamstring tendon is accidental (tendon rupture or tendon variation) or ineffective, the peroneal longus tendon will be a good choice.

“…However, in all of the PFA revisions, the conversion was very simple and was performed using non-stemmed TKA implant. For the second generation of PFA implants, other authors have noted the ease of conversion to TKA [25,26].…”

Background: Severe isolated patellofemoral osteoarthritis is usually treated by total knee arthroplasty (TKA) in the majority of the world but patellofemoral arthroplasty (PFA) has been a viable alternative for many years although there have been concerns about implant longevity. The purpose of this research was to compare the clinical outcome of patients with isolated patellofemoral osteoarthritis who received PFA or TKA. Methods: From January 2015 to December 2017, 42 patients with isolated patellofemoral osteoarthritis who received PFA were included in the PFA group. In this period, a matched cohort of 42 patients with isolated patellofemoral osteoarthritis who received TKA (TKA group) was chosen for comparison. The results of the two groups were compared before surgery and at last follow-up using Tegner Activity Scale, Range of motion of the knee, Oxford Knee Score and Short Form 36 Health Survey. Differences were considered statistically significant at p < 0.05.Results: The mean follow-up time was 3.5 ± 0.3 and 3.4 ± 0.3 years in the PFA and TKA groups (p = 0.13), respectively. No significant difference in preoperative knee scores were found between the two groups (p > 0.05). However, postoperative, compared with Tegner Activity Scale, Range of motion, Oxford Knee Score and Short Form 36 Health Survey, the PFA group performed significantly better results (p < 0.05). The Kaplan-Meier implant survivorship with 95% confidence intervals was 94.12 % in the PFA group and 94.74% in the TKA group (p = 0.49).Conclusions: The patients with isolated patellofemoral osteoarthritis who underwent PFA had shown better clinical outcomes and higher quality of life. We believed that for the treatment of isolated patellofemoral osteoarthritis, the PFA was a less invasive procedure with improved patient satisfaction and range of motion at medium term follow-up.
