“…One study displayed a more complicated relationship between post-resection patellar thickness and outcome measures. Recently, Lee et al 25 prospectively assessed the effect of patellar thickness on short-term patientreported outcome measures using Knee Society Scoring System and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores in a Chinese population (169 knees). After a mean follow-up of 13 months, the au-thors found that those patients with a residual patellar thickness of less than 12 mm had a significantly lower WOMAC score than those with a thickness of greater than 12 mm (P=.035).…”

“…Similarly, in the previously mentioned study conducted by Lee et al, 25 in addition to analyzing patient-reported out-comes, the authors also examined potential complications that could lead to a reoperation. After the mean follow-up of 13 months, there were no instances of loosening among the cohort (0 of 169 arthroplasties), regardless of their patellar thickness.…”

Orthopedic surgeons resurface the patella during total knee arthroplasty to avoid complications such as pain, patello-femoral arthritis, and patellar maltracking and to reduce the risk for reoperation. However, many complications, such as decreased range of motion, increased fractures, and polyethylene wear, have been described with this procedure. One determinant when resurfacing a patella is the thickness of its cuts. This review aims to investigate the relationship between patellar thickness and outcome parameters such as range of motion, patient-reported outcomes, periprosthetic fractures, and reoperations.

“…A study conducted by Lee et al 40 found that 31% of patients who underwent knee replacement with patellar resurfacing had preoperative patella thickness <21 mm, and this group of patients will have poorer gain in range of motion at 1-year follow-up. Residual patella thickness <12 mm also showed a poorer result at 1-year follow-up even in the absence of patellar fracture or implant loosening.…”

Management of the patella during primary total knee arthroplasty remains an unanswered question. Internationally, there is significant variation in the approach to resurfacing with some geographic regions resurfacing almost universally, and other regions rarely resurfacing. This difference in preference is a result of the different geographic locations, and is influenced by where the surgeons were trained, what was taught during their training, their patients' patellae profiles, financial condition and hospital policy where the surgeons practise. In this current concepts review, we investigate where we are now with patellar resurfacing during total knee arthroplasty from an international perspective, and the differences in outcomes between resurfaced and non-resurfaced patellae. In the end, the decision to resurface or not to resurface remains at the surgeon's discretion and is highly influenced by both medical and non-medical reasons. This review includes an alternative method to address anterior knee pain, which can be an additional management option apart from resurfacing or non-resurfacing for patients where patellar resurfacing is not a viable option, such as in very thin patellae. Moreover, we will also describe other variables that may play a role in causing persistent anterior knee pain, for instance soft tissue imbalance around the patella or improper positioning of the components. It may be important to address these factors to prevent undesirable postoperative outcomes.

“…A study was demonstrated that an increase in thickness 1 mm or more postoperatively was associated with lower gain in WOMAC score [3]. A cadaveric study with and without patellar resurfacing demonstrated that changing in patellar thickness had an infl uence tibio-femoral kinematics.…”

Background: Anterior knee pain(AKP) was a common complication after total knee replacement(TKR). This condition can be occurred in both patellar resurfacing and non-resurfacing technique. An increase in patellar thickness 1 mm or more postoperatively was associated with lower gain in WOMAC score. Objective:To compare AKP and up and down stair function after patellar thickness reduction and patellar non-resurfacing TKR. Materials and Methods:A retrospective comparative study of was designed. All patients who had been TKR since March 2015 and December 2017 were included. The questionnaires of 2 easy questions about pain over patellar region and walking up-down stairs performance were sent to all patients by letters. The patient's characteristics were collected from inpatient medical records. AKP was defi ned as pain scale 3-10. Data were analyzed by t-test and fi sher's exact using STATA 12 (demonstrated version). P-value < 0.05 was considered signifi cant.Results: 60 questionnaires were sent and 49 evaluations were received. 26 patients were patellar non-resurfacing(PNR) group and 23 patients was patellar thickness reduction(PTR) group. Duration after TKR to questionnaires response were 12-43 months. The prevalence of AKP and knee function of up and down stair were not signifi cantly different in both groups. The severity of AKP in PNR group (5.1+1.2) was signifi cant (p-value < 0.01) higher than PTR group (3.4+0.8).Conclusion: Patellar thickness reduction in total knee replacement could reduce the severity of anterior knee pain compared to patellar non-resurfacing technique.
