“…Several reports have been published with similar clinical and functional outcomes, with or without patellar resurfacing [1,5,20,21]. In addition, several complications after resurfacing such as patella fracture, dislocation or avascular necrosis have been reported [3].…”

Purpose Knee pain after total knee arthroplasty may be caused by an unresurfaced patella. Secondary isolated resurfacing of the previously unresurfaced patella in total knee arthroplasty remains controversial. The aim of this retrospective study was to evaluate the outcome after patellar resurfacing as a second stage procedure. Methods The study included 22 patients (13 female/nine male) who underwent resurfacing of the patella with a mean follow-up of 61.8±39.2 months. The mean age of the patients was 60±9.7 years at the time of operation. The average period between total knee arthroplasty and patellar resurfacing was 26.3±15.2 months. The patient's subjective satisfaction was assessed by a custom-made questionnaire.

“…A malpositioned femoral component increases the patellofemoral contact pressure, thus affecting the clinical outcome and the long-term survivorship of the implant [6,12]. However, in patients with persistent AKP after TKA, the source of symptoms cannot be identified [2,3,14].…”

“…That it is controversial to resurface the patella in total knee arthroplasty (TKA) remains as a topic in the literature because of the higher incidence of anterior knee pain after TKA without patellar resurfacing [1,2], which was reported to be between 5 and 47% of patients [3][4][5][6][7], and the general idea that the aetiology of anterior knee pain is related to the patellofemoral joint. Some authors recommend routinely resurfacing the patella [7][8][9][10][11], while others have reported no evidence to support routine patellar resurfacing.…”

“…Some authors recommend routinely resurfacing the patella [7][8][9][10][11], while others have reported no evidence to support routine patellar resurfacing. The patella complications were found more often in the resurfaced group than in the group without resurfacing [12][13][14][15][16].…”

Controversies existing over resurfacing the patella in total knee arthroplasty remain in the literature. The purpose of this review was to evaluate the effectiveness of resurfacing versus nonresurfacing the patella in total knee arthroplasty. We searched the Cochrane Library, MEDLINE and EMBASE for published randomised clinical trials relevant to patellar resurfacing. The relative risk of reoperation was significantly lower for the patellar resurfacing group than for the nonresurfacing group (relative risk 0.57, 95% confidence interval 0.38-0.84, P=0.004). The overall incidence of postoperative anterior knee pain of the 1,421 knees included was 12.9% in the patellar resurfacing group and 24.1% in the nonresurfacing group. The existing evidence indicates that patellar resurfacing can reduce the risk of reoperation with no improvement in postoperative knee function or patient satisfaction over total knee arthroplasty without patellar resurfacing. Whether it can decrease the incidence of anterior knee pain remains uncertain.

“…Patellar resurfacing in TKA has become more routine despite controversy about whether it results in improved patient outcomes [10,12,13,15,42]. With the number of primary TKA procedures expected to increase by more than sixfold in the next 25 years and the number of revision procedures expected to double within the next 8 years [26], management of the failed patellar component at the time of revision TKA becomes an essential aspect of the revision procedure.…”

There are a number of options available to manage the patella when revising a failed total knee arthroplasty. If the previous patellar component is wellfixed, undamaged, not worn, and compatible with the femoral revision component, then it can be retained. When a patellar component necessitates revision and is removed with adequate remaining patellar bone stock, an onlay-type all-polyethylene cemented implant can be used. Management of the patella with severe bony deficiency remains controversial. Treatment options for the severely deficient patella include the use of a cemented all-polyethylene biconvex patellar prosthesis, patellar bone grafting and augmentation, patellar resection arthroplasty (patelloplasty), performing a gull-wing osteotomy, patellectomy, or the use of newer technology such as a tantalum (trabecular metal) patellar prosthesis. Severe patellar bone deficiency is a challenging situation because restoration of the extensor mechanism, proper patellar tracking, and satisfactory anatomic relationships with the femoral and tibial components are critical for an optimal clinical outcome.
