Patellofemoral Arthroplasty in the Treatment of Patellofemoral Arthritis: Rationale and Outcomes in Younger Patients

A matched-pair comparison of inlay and onlay trochlear designs for patellofemoral arthroplasty: no differences in clinical outcome but less progression of osteoarthritis with inlay designs

“…Relative contraindications for PFA were uncorrected patellofemoral instability, patellofemoral malalignment, and tibiofemoral malalignment. In those patients, PFA was combined with patellar stabilizing and/or realignment procedures [4,27,30,47], according to an algorithm described in detail elsewhere [22]. For the purpose of this study, only patients who underwent isolated PFA were included (n = 64).…”

Prospective evaluation of anatomic patellofemoral inlay resurfacing: clinical, radiographic, and sports-related results after 24 months

“…We therefore performed combined PFIR in these patients [4,32,35,59], according to the treatment algorithm described in Fig. 2.…”

Patellofemoral arthroplasty: a multi-centre study with minimum 2-year follow-up

“…These preoperative tests may be particularly useful as corroborative evidence in deciding if grade 3 Outerbridge [21] damage in the patellofemoral joint is accounting for the patient's symptoms. Postoperative stiffness and arthrofibrosis have been a common problem after PFA [12]. A history of arthrofibrotic healing after prior knee operations should signal caution to the surgeon and patient.…”

“…Its features were based on the Kinemax Plus TKA design (Howmedica, Limerick, UK). Initial reports on short-and long-term results of this prosthesis have been encouraging with low complication rates and excellent outcomes [1,2,12]. However, with the exception of one series by the designer of the prosthesis, these reports have included relatively few knees or have had high loss of follow-up.…”
