“…Hence, in the 109 knees, 66 with isolated medial OA as well as 15 with medial and co‐existing PFJ OA (48.2%) were eligible for Oxford medial UKA, while 11 with isolated lateral OA (6.5%) were indicated for Oxford lateral UKA. According to our criteria, both patients with isolated PFJ OA showed K/L grade 2 in medial and lateral compartments of the tibiofemoral joint, and were not indicated for PFJR. As a result, 76 (45.2%) knees could not be treated with UKA and were indicated for treatment with TKA instead (Table , Fig.…”

“…Patellofemoral OA is a common condition, confirmed by the fact that it was present in 33.9% of the knees in our study. However, isolated PFJ OA (K/L grade ≥3) is rare, and was only found in 2 knees.…”

“…This isolated PJF OA could be treated by PFJR as an alternative to TKA; however, strict selection criteria are critical for its success. There should be no significant degeneration in the tibiofemoral joint and a K/L classification of no more than grade 1. Hence, neither of the 2 knees identified as isolated PFJ OA in the present study could be treated with PFJR, due to the presence of K/L grade 2 in the tibiofemoral joint.…”

“…Similarly, isolated lateral compartment knee OA can be treated by lateral UKA. In addition, isolated primary PFJ OA and secondary PFJ OA are indicated for PFJR, but only if minimal OA is evident in the tibiofemoral joint (K/L grade <2).…”

“…Good outcomes have been reported for the Oxford mobile‐bearing UKA in overweight, younger, and more active patients, as well as in the presence of co‐existent PFJ degeneration. In addition, isolated PFJ OA could be treated with PFJR instead of TKA.…”

PurposeThe aims of the present study were (1) to evaluate the survival of patellofemoral joint (PFJ) arthroplasty in a large cohort of patients using data obtained from an Italian regional arthroplasty registry and (2) to collect clinical outcomes of a subgroup of patients, with a minimum follow‐up of 4 years. The hypotheses were that PFJ arthroplasty is a procedure that had good survival and clinical outcomes, not inferior to those reported in the literature for primary total knee arthroplasty (TKA).MethodsThe Register of Orthopaedic Prosthetic Implants (RIPO) of Emilia‐Romagna (ER) (Italy) database was searched for the inclusion of all PFJ arthroplasties implanted between 2003 and 2019. PFJ arthroplasties were excluded if they were implanted in patients who lived outside of the ER. The survival information was extrapolated from the RIPO considering the partial or total revision of the implant as failure; moreover, a subgroup of patients was contacted and interviewed by telephone to collect clinical outcomes. Descriptive statistics were used to summarise the data. The survival curve was calculated and plotted using the Kaplan–Meier method.ResultsA total of 126 arthroplasties in 114 patients were included in the final analysis (mean age at surgery 60.1 ± 11.5 years old). The main causes of patellofemoral arthroplasty were primary osteoarthritis (88%) and posttraumatic arthritis (7%). The survival was 90.4 ± 30.6 and 78.8 ± 51.5 at 5 and 10 years of follow‐up, respectively. At the latest follow‐up, 23 implants failed (18.3%). The main cause of revision was osteoarthrosis progression (34.8%). A total of 44 patients were contacted by telephone to collect clinical outcomes: Western Ontario and McMaster Universities Osteoarthritis Index, functional Knee Society Score, Forgotten Joint Score and Oxford Knee Score. These patients reported good to excellent scores at a medium follow‐up of 10.3 ± 4.7 years.ConclusionsThe PFJ showed good survival and clinical outcomes and could be considered a valuable option for patients affected by isolated patellofemoral osteoarthritis.Level of EvidenceLevel IV.
