Background: Improved knee prosthesis designs have led to an increase in the use of patellofemoral arthroplasty as a primary treatment option in recent times. We report the early results and outcomes of the Zimmer Gender Solutions Patello-Femoral Joint (PFJ) system used to treat isolated patellofemoral osteoarthritis (PFA). Methods: We retrospectively reviewed and analysed data of patients who underwent PFJ replacement (PFJR) at our institution with a minimum follow-up of 2 years. Results: Median Oxford Knee score (OKS) was 38 (interquartile range, 28 to 42) at the latest follow-up with a significant improvement from preoperative scores (p < 0.0005). Median OKS was 40 for unilateral PFJRs and 39 for nonobese patients (body mass index [BMI] < 30 kg/m2). There was no significant difference in OKS between unilateral and bilateral procedures (p = 0.462). Likewise, there was no significant difference in OKS between obese and nonobese patients (p = 0.272). Two knees (4%) were revised for progression of osteoarthritis. No complications were reported related to infectious or thromboembolic causes. Conclusions: Our study showed good early results of the PFJ system, at least equal to those of other leading brands in the National Joint Registry for England, Wales and Northern Ireland (NJR). There have been no complications related to either the implantation technique or prosthetic design for this new implant. Progression of tibiofemoral arthritis remains a major concern. Our study also suggests that PFJR in obese patients and bilateral procedures can have good results.

Background: The Targon FN implant was developed in 2007 to treat intracapsular neck of femur fractures. Early results from thedesign centre have shown good results in terms of fracture complications. We wished to see if these results can be reproduced inan independent institution. Methods: The records of consecutive patients, treated with this implant between 2008 and 2011 at Queen Elizabeth Hospital,were identified and collected for this study. Operations were performed by all grades of surgeons under supervision as appropriate. These patients went on to have both clinical and radiological assessment for fracture healing and function. Results: Fifty-one patients were identified with 43 patients available for final follow-up. The average age was 66 years with aminimum follow-up of 24 months. A non-union rate of 0% in the undisplaced fracture group and 1 in 12 (8%) in the displaced fracturegroup was observed. An avascular necrosis rate of 6% and 8% was observed for undisplaced and displaced fracture types,respectively. No significant change in premorbid to postoperative ambulation was observed and there was no wound complication. Conclusions: Our study shows similar results with those of the design centre and which are superior to those currently found inthe literature for the more traditional fixation methods. It also shows that the promising results with this new implant as seen fromthe design institutions can be reproduced by all cadres of surgeons in non-specialist practice.
