“…The V-shaped patellabutton is a concern for some authors because conversion to TKA means revising the patella as well [12]. To our knowledge, there is no discussion if the patella should be resurfaced or not in PFA, opposed to TKA [13,14]. In any case, in our experience the patellabutton does not cause problems in revision cases.…”

A 21 % conversion rate to total knee arthroplasty of a first-generation patellofemoral prosthesis at a mean follow-up of 9.7 years (range, 110-200). Median VAS Pain was 30 (range, 0-80) and VAS Satisfaction median was 90 (range, 50-100). Thirteen (62 %) PFAs were rated excellent, six (28 %) as good and two (10 %) as fair. Twelve (36 %) of the cases required further surgery within 4 years after implantation. Seven of these (21 %) were converted to TKA after a mean time of 5.5 years, five out of seven were converted because of ongoing tibiofemoral osteoarthritis (TFOA).Conclusions We found a rate of 21 % (7/33) conversion of the Richards' II PFA to TKA after a mean of 5.5 years; 71 % (5/7) of cases were because of TFOA. We strongly advise not to use PFA if there is any sign of joint disease in other compartments than patellofemoral.

“… 139 The following study, conducted in 2014, found significantly improved Knee Injury and Osteoarthritis Outcome Scores and Oxford Knee Scores in the patelloplasty group compared to traditional management; however, there was no significant difference in Knee Society Function or Pain Scores. 140 In both studies, the authors concluded that patelloplasty was better than traditional patellar retention in improving knee function and quality of life.…”

“…In the last ten years, two studies have compared patelloplasty – defined as osteophyte removal, denervation, patellar cartilage resection, and reshaping of the patellar facets – to osteophyte removal and denervation alone. 139 , 140 The first study done in 2012 found that the patelloplasty group had significantly better functional scores and patient satisfaction, but there was no difference in postoperative anterior knee pain. 139 The following study, conducted in 2014, found significantly improved Knee Injury and Osteoarthritis Outcome Scores and Oxford Knee Scores in the patelloplasty group compared to traditional management; however, there was no significant difference in Knee Society Function or Pain Scores.…”

Patellar management during total knee arthroplasty: a review

et al. 2021

View full text Add to dashboard Cite

The optimal management of the patella during total knee arthroplasty (TKA) remains controversial and surgeons tend to approach the patella with one of three general mindsets: always resurface the patella, never resurface the patella, or selectively resurface the patella based on specific patient or patellar criteria. Studies comparing resurfacing and non-resurfacing of the patella during TKA have reported inconsistent and contradictory findings. When resurfacing the patella is chosen, there are a number of available patellar component designs, materials, and techniques for cutting and fixation. When patellar non-resurfacing is chosen, several alternatives are available, including patellar denervation, lateral retinacular release, and patelloplasty. Surgeons may choose to perform any of these alone, or together in some combination. Prospective randomized studies are needed to better understand which patellar management techniques contribute to superior postoperative outcomes. Until then, this remains a controversial topic, and options for patellar management will need to be weighed on an individual basis per patient. Cite this article: EFORT Open Rev 2021;6:861-871.

“…They found that patelloplasty was better in both relieving AKP and improving patient's satisfaction and knee function. 59 Župan et al 60 reported better clinical outcomes in patients with patelloplasty with respect to the simple denervation and removal of osteophytes. They found better outcomes in Knee injury and Osteoarthritis Outcome Score (KOOS) and in Oxford Knee Score, but revealed no significant differences in KSS and pain scores.…”

Total knee arthroplasty (TKA) is the best treatment for advanced knee osteoarthritis and it has proven to be durable and effective. Anterior knee pain (AKP) is still one of the most frequent complications after TKA, but sometimes no recognized macroscopic causes can be found. The correct treatment of patella is considered the key for a proper management of AKP. The inclusion of patellar resurfacing during TKA has been described as a potential method for the reduction of AKP. After surgeons started to resurface the patella, new complications emerged, such as component failure, instability, fracture, tendon rupture, and soft tissue impingement. Patelloplasty has been proposed as a good alternative to resurfacing but whether or not to resurface the patella is still a controversial topic in the literature. Therefore, patellofemoral joint is a complex critical aspect in TKA and choosing between the several options of treatment of patella could not be sufficient. In this review, evidence-based studies do not succeed in resolving this difficult argument. The accurate management of the so-called “third space” should include an accurate assessment of cartilage layers, balance of soft tissue, preoperative anterior tracking, and positioning of the femoral and tibial components. In fact, the selection of suitable implants and adherence to proper surgical technique are the fundamental principles for the success of TKA.
