AI Article Synopsis
- The study investigates the effectiveness of patellofemoral arthroplasty on patients with isolated patellofemoral osteoarthritis over an 11-year period.
- Analysis of patient outcomes using the Oxford Knee Score showed significant improvement post-surgery, with average score reductions indicating better knee function.
- Findings suggest that the improvement in knee function is not influenced by implant type, gender, age, or BMI, but further research is necessary to evaluate long-term results.
Article Abstract
Purpose: The purpose of this prospective study was to present the experience of a single center on patellofemoral arthroplasty, in terms of patient-related outcomes.
Method: From January 2005 to January 2016, 42 patients with isolated patellofemoral osteoarthritis were treated. The patients were assessed using the Oxford Knee Score preoperatively, and one, five, and eight year(s) after surgery. The data of the patients were analyzed using linear mixed effects models. A P value of 0.05 was considered statistically significant.
Results: Among 42 patients who underwent patellofemoral arthroplasty, only 25 patients (31 limbs involved) had records up to 5 years. There was a significant clinical improvement of Oxford Knee Score postoperatively (P < 0.05), lowering the score on average by 10.4 ± 1.5 one year after surgery and 8.9 ± 1.9 five years after surgery. This improvement was independent of the types of implants (P > 0.05), gender (P > 0.05), age (P < 0.05), and body mass index (BMI) (P < 0.05).
Conclusion: Patellofemoral arthroplasty can significantly improve the knee function, and this improvement is independent of the type of implant, gender, age, and BMI. However, further studies will need to assess the long-term outcomes of PFA.

Background And Purpose: In contemporary medial unicompartmental knee arthroplasty (mUKA), non-lateral patellofemoral osteoarthritis (PFOA) is not considered a contraindication. However, we still lack knowledge on the association of PFOA severity on patient reported outcome measures (PROMs) after mUKA. We aimed to examine the association between PFOA severity and PROM-score changes after mUKA.

Background And Objective: The efficacy of medial unicompartmental knee arthroplasty (UKA) in patients with intraoperatively identified patellofemoral osteoarthritis (PFOA) has been a subject of debate. This retrospective study aimed to investigate the early outcomes of UKA in patients with varying intraoperative PFOA conditions and to explore the relationship between the location of PFOA and the position of the prosthesis post-UKA. Our aim was to determine whether the presence of PFOA affects the short-term success of medial UKA.

: Abnormalities in patellar tracking, often overlooked in surgical planning, have been identified as a contributing factor to total knee arthroplasty (TKA) complications, including anterior knee pain, patellar subluxation, and dislocation. This study aims to evaluate the repeatability of a novel intraoperative setup for assessing patellofemoral kinematics and its interaction with prosthesis design and positioning during surgery. This setup may support personalized alignment techniques in TKA, potentially improving surgical outcomes.

Background: The study focused on kinematically aligned total knee arthroplasty (KA TKA). It identified which coronal plane alignment of the knee (CPAK) types are associated with a higher proportion of medial deviation of the 6° prosthetic trochlear groove (PTG) relative to the quadriceps' line of pull and whether medial deviation adversely affected the Forgotten Joint Score (FJS). The research calculated the minimum PTG angle required to prevent medial deviation by at least 2° in all patients.
