“…The results reflect current literature, which reports improvements in close to 50% of cases, with secondary resurfacing of the patella [ 3 , 6 - 8 ], but our knowledge of indicators that would reliably identify those patients who may develop AKP and how best to treat them to avoid dissatisfaction remains deficient [ 2 ]. A recent study revealed improvements in knee scores in a similar percentage of cases, with a specific cause for anterior knee pain being unknown [ 16 ].…”

“…The first record of resurfacing of the patella performed in combination with a condylar resurfacing arthroplasty was performed by Groeneveld in 1970 [ 1 , 2 ], with most knee replacement systems having an option for patella resurfacing since the beginning of the 1980s [ 2 , 3 ].…”

“…In revision surgery of total knee prosthesis, secondary resurfacing of the patella is controversial as well. Usually performed in patients with anterior knee pain, where the patella was unresurfaced in the index procedure, improvements are expected in less than 60% of patients [ 3 , 6 - 8 ]. The reasons for this are unproven for now, with a number of studies presenting conflicting information [ 9 - 12 ].…”

Secondary patella resurfacing is a controversial procedure which is applied in patients with anterior knee pain after a bicondylar knee arthroplasty (with unresurfaced patella). A group of 46 patients were submitted to this procedure and their satisfaction, range of motion and pain improvement was evaluated. 52.2% of the patients were satisfied with the procedure, with an improvement in pain (Visual Analogue Scale) of 65% and an improvement in range of motion in 56,5%, with roundabout half of the patients having no resolution to their complaints. Whilst an improvement was not achieved in all patients, as it was initially hypothesised, this procedure should be considered when a revision knee arthroplasty is performed with an unresurfaced patella.

“…The lateral femoral condyle has a larger distal radius which is more prominent anteriorly and less prominent distally than the medial femoral condyle. 2 This increases the difficulty of identifying the osseous landmarks while templating the femoral component.…”

“…1,2 Oversizing of the femoral component can lead to 'overstuffing' of the patellofemoral joint and a reduction in the post-operative range of knee flexion. 3 Conversely, undersizing of the component can lead to a flexion-extension mismatch, with instability in flexion.…”

The reliability and accuracy of digital templating in total knee replacement

We aimed to determine the reliability, accuracy and the clinical role of digital templating in the pre-operative work-up for total knee replacement. Initially a sample of ten pre-operative digital radiographs were templated by four independent observers to determine the inter- and intra-observer reliability of the process. Digital templating was then performed on the radiographs of 40 consecutive patients undergoing total knee replacement by a consultant surgeon not involved with the operation, who was blinded to the size of the implant inserted. The Press Fit Condylar Sigma Knee system was used in all the patients. The size of the implant as judged by templating was then compared to that of the size used. Good inter- and intra-observer agreement was demonstrated for both femoral and tibial templating. However, the correct size of the implant was predicted in only 48% of the femoral and 55% of the tibial components. Albeit reproducible, digital templating does not currently predict the correct size of component often enough to be of clinical benefit.
