“…Numerous numbers of studies on patellofemoral or femorotibial joint problems have been published in the literature. 2 , 3 , 4 , 5 , 6 , 7 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 However, the focus of the present case was on the post-cam function. To our knowledge, only a few cases of post-cam dysfunction have been reported.…”

Soft tissue impingements are well-known complications of total knee arthroplasty. The impingements usually occur between the medial or lateral femoral component and tibial insert, and between the patella and femoral components. We report a rare case of impingement of the soft tissue between the femoral intercondylar fossa and post of the polyethylene insert, which caused pain and walking disability. After the surgery for the arthroscopic removal of the soft tissue, the symptoms disappeared. However, prosthetic loosening of the femur occurred several months after the arthroscopic surgery, requiring revision surgery. We would propose to call this symptom as post-cam clunk syndrome.

“…Within their study, however, the patella was not resurfaced, making comparisons with this current study unreliable. More recently Rajshekhar et al 19 evaluated the HP Sigma Press Fit Condylar component (group B) in a noncomparative study and identified an incidence of 2% patellar clunk. Their study is more limited than the current study because it includes only 133 patients who all received the HP Sigma Press Fit Condylar component and bearing choice was not identified.…”

Patellofemoral crepitus is a known complication of posterior stabilized (PS) total knee arthroplasty (TKA). This study compared the incidence of patellofemoral crepitus between two femoral components designs. Between January 2005 and August 2010, 1,120 patients with complete 2-year follow-up had a PS TKA with two different prosthetic designs (group A, 553 patients; group B, 567 patients). Records were reviewed to identify the incidence of total, symptomatic, and operative patellofemoral crepitus. No statistical differences were observed in the incidence of total patellofemoral crepitus (group A 14.1%, group B 14.5%; = 0.932) or symptomatic patellofemoral crepitus (group A 5.6%, group B 4.2%; = 0.334). The incidence of operative crepitus was greater in group A (3.3%) than in group B (1.3%; = 0.026). Analysis of mobile versus fixed bearing designs showed a higher incidence of total patellofemoral crepitus in mobile bearing TKA (16.04 vs. 4.93%; = 0.006) within group B only. Femoral component design with a smoother intercondylar box transition zone resulted in a lower incidence of operative patellofemoral crepitus. No statistical differences were noted regarding the incidence of total and symptomatic patellofemoral crepitus. Mobile bearing TKA exhibited greater total crepitus within group B. Level III.

Patellar clunk in total knee arthroplasty using modified Sigma posterior stabilized femoral component

Abstract: Removal of the sharp ridge in the intercondylar groove in the newer implant seems to have been effective in reducing the incidence of the patellar clunk. It also indicates that the sharp ridge was the most probable cause of the clunk.
