Summary: This systematic review analyzed 33 studies published in the last 15 years on second-generation (2G) patellofemoral arthroplasty (PFA), showing promising results in functional outcomes and survivorship in patients with isolated patellofemoral OA. The postoperative Oxford Knee Score and American Knee Society Score remained at high levels.

Summary: In patients with isolated patellofemoral osteoarthritis (PF-OA), patellofemoral arthroplasty (PFA) showed higher activity levels and better functional recovery in the first two years postoperatively compared to total knee arthroplasty (TKA). There was no significant difference in complications, revision rates, and satisfaction rate between the two procedures.

Summary: The study found that in treating isolated patellofemoral osteoarthritis, second-generation patellofemoral arthroplasty (2G PFA) showed similar results to total knee arthroplasty (TKA) in terms of revision rates, complications, and patient-reported outcome measures (PROMs).

Summary: This review presents recent literature on the treatment of patellofemoral arthritis, discussing risk factors, physical exam maneuvers, radiographs, non-operative and pharmacologic management options, injection therapies, surgical treatment algorithm, and other treatment options. Patellofemoral osteoarthritis is a challenging orthopedic problem with unique epidemiology, biomechanics, risk factors, and treatment options compared to tibiofemoral osteoarthritis.

Summary: This study reports the long-term clinical outcomes of isolated MPFL reconstruction for recurrent patellar instability. Overall, the results suggest that this surgical intervention is an effective long-term treatment option with low rates of recurrence.

Summary: Factors such as baseline meniscus surgery, single-leg-hop limb symmetry index, and hamstring strength imbalance were found to be associated with the development of tibiofemoral and patellofemoral osteoarthritis in patients with anterior cruciate ligament injury. Further research is needed to investigate whether interventions can prevent or delay the onset of osteoarthritis in this population.

Summary: The study found that extreme patellar height, lower sulcus angle, and patients with type III patella are associated with more severe PFOA.

Summary: By observing three-dimensional magnetic resonance images from a cohort population, we clarified the frequency, localization, and morphological progression of patellofemoral osteoarthritis. The prevalence of patellar cartilage defects was higher in the medial than lateral regions, and the defects were divided into confined and unconfined types.

Summary: This study examined the high prevalence of trochlear dysplasia (TD) in isolated lateral patellofemoral osteoarthritis (ILPFOA) and found that TD plays an important role in the onset of ILPFOA. TD was more severe in patients under 45 years of age, while non-TD cases were more likely to have lateral facet deformity and be overweight.

Summary: Isolated medial patellofemoral ligament reconstruction as the primary surgical treatment for lateral patellar dislocation in skeletally immature patients provides excellent midterm results regardless of patellar height and trochlear dysplasia. However, redislocation can still occur in some patients, and a higher degree of retropatellar chondral lesion is associated with a poorer clinical outcome.

Summary: This study aimed to investigate the association between 3D patellar shape and isolated magnetic resonance imaging (MRI)-based patellofemoral osteoarthritis (PFOA), as well as the morphological features and clinical symptoms of PFOA. The results showed that certain shape variants were significantly associated with the presence of PFOA and structural abnormalities. Multiple associations were also found between patellar shape and clinical symptoms. The findings suggest that patellar shape may serve as an early detectable risk factor for PFOA.

Summary: The study found that individuals with isolated patellofemoral osteoarthritis (PFOA) exhibit impairments in muscle capacity of the knee and hip, as well as higher levels of pain, stiffness, and compromised physical functioning compared to healthy controls.

Summary: This study assessed the ability of texture features to detect patellofemoral osteoarthritis (PFOA) from knee lateral view radiographs. The results showed that using texture features improved the prediction performance and helped predict PFOA.

Summary: This retrospective study compared the outcomes of three surgical techniques on patients with knee osteoarthritis and found that robotic-assisted surgery can better improve patellar tilt. The surgical technique and implant design did not significantly affect the functional recovery and revision rate in patients.

Summary: Isolated MPFL reconstruction for recurrent patellofemoral instability yields reliable surgical outcomes, while patients with pathoanatomical predisposing factors may experience poorer surgical results.
