“…Conversely, TVV rotation was consistent for all three activities as demonstrated by the small average standard deviation ( Table 1 and Figure 2A ) and the low RMSD values compared to the other DOFs ( Table 2 ). These results agreed with several studies that have measured small amounts of TVV during activities ( Myers et al, 2012 ; Kefala et al, 2017 ; Thomeer et al, 2021 ). However, TVV was also affected by weight-bearing as demonstrated by the scaled RMSD values that showed these changes were on the order of the natural TVV range of motion (e.g., scaled RMSD of 0.7 for chair rise).…”

“…As shown in prior studies ( Hefzy et al, 1992 ; Li et al, 2007 ; Thomeer et al, 2021 ), there was a strong correlation between patellar flexion and tibiofemoral flexion both on average and across individuals (e.g., average R 2 = 0.96 for knee extension). Moreover, weight-bearing had the smallest effect on patellar flexion with the lowest scaled RMSD of all the kinematics measured ( Table 2 ).…”

“…While several studies have presented the tibiofemoral or patellofemoral kinematics separately, few studies have focused on investigating the kinematic relationship between joint motions ( Hefzy et al, 1992 ; Li et al, 2004 ; Li et al, 2007 ; Seisler and Sheehan 2007 ; Thomeer et al, 2021 ). In agreement with in vitro studies, both tibial internal rotation and patellar medial tilt increased with knee flexion ( Hefzy et al, 1992 ).…”

“…Yet, reported measurements of both tibiofemoral and patellofemoral motion of the healthy living knee during activities of daily living are very rare. Studies have reported precision kinematics for the tibiofemoral joint ( Lafortune et al, 1992 ; Andriacchi and Dyrby 2005 ; Li et al, 2005 ; Kefala et al, 2017 ) and the patellofemoral joint ( Schutzer et al, 1986 ; Koh et al, 1992 ; Kefala et al, 2021a ), yet only a few have investigated the combined motion of tibiofemoral and patellofemoral joints in healthy living subjects ( Li et al, 2007 ; Seisler and Sheehan 2007 ; Thomeer et al, 2021 ).…”

Quantification of natural knee kinematics is essential for the assessment of joint function in the diagnosis of pathologies. Combined measurements of tibiofemoral and patellofemoral joint kinematics are necessary because knee pathologies, such as progression of osteoarthritis and patellar instability, are a frequent concern in both articulations. Combined measurement of tibiofemoral and patellofemoral kinematics also enables calculation of important quantities, specifically patellar tendon angle, which partly determines the loading vector at the tibiofemoral joint and patellar tendon moment arm. The goals of this research were to measure the differences in tibiofemoral and patellofemoral kinematics, patellar tendon angle (PTA), and patellar tendon moment arm (PTMA) that occur during non-weight-bearing and weight-bearing activities in older adults. Methods: High-speed stereo radiography was used to measure the kinematics of the tibiofemoral and patellofemoral joints in subjects as they performed seated, non-weight-bearing knee extension and two weight-bearing activities: lunge and chair rise. PTA and PTMA were extracted from the subject’s patellofemoral and tibiofemoral kinematics. Kinematics and the root mean square difference (RMSD) between non-weight-bearing and weight-bearing activities were compared across subjects and activities. Results: Internal rotation increased with weight-bearing (mean RMSD from knee extension was 4.2 ± 2.4° for lunge and 3.6 ± 1.8° for chair rise), and anterior translation was also greater (mean RMSD from knee extension was 2.2 ± 1.2 mm for lunge and 2.3 ± 1.4 mm for chair rise). Patellar tilt and medial–lateral translation changed from non-weight-bearing to weight-bearing. Changes of the patellar tendon from non-weight-bearing to weight-bearing were significant only for PTMA. Conclusions: While weight-bearing elicited changes in knee kinematics, in most degrees of freedoms, these differences were exceeded by intersubject differences. These results provide comparative kinematics for the evaluation of knee pathology and treatment in older adults.

We combined mobile biplane X‐ray imaging and magnetic resonance imaging to measure the regions of articular cartilage contact and cartilage thickness at the tibiofemoral and patellofemoral joints during six functional activities: standing, level walking, downhill walking, stair ascent, stair descent, and open‐chain (non‐weight‐bearing) knee flexion. The contact centers traced similar paths on the medial and lateral femoral condyles, femoral trochlea, and patellar facet in all activities while their locations on the tibial plateau were more varied. The translations of the contact centers on the femur and patella were tightly coupled to the tibiofemoral flexion angle in all activities (r2 > 0.95) whereas those on the tibia were only moderately related to the flexion angle (r2 > 0.62). The regions of contacting cartilage were significantly thicker than the regions of non‐contacting cartilage on the patella, femoral trochlea, and the medial and lateral tibial plateaus in all activities (p < 0.001). There were no significant differences in thickness between contacting and non‐contacting cartilage on the medial and lateral femoral condyles in all activities, except open‐chain knee flexion. Our results provide partial support for the proposition that cartilage thickness is adapted to joint load and do not exclude the possibility that other factors, such as joint congruence, also play a role in regulating the structure and organization of healthy cartilage. The data obtained in this study may serve as a guide when evaluating articular contact motion in osteoarthritic and reconstructed knees.

The aim of this randomized controlled trial was to measure and compare six‐degree‐of‐freedom (6‐DOF) knee joint motion of three total knee arthroplasty (TKA) implant designs across a range of daily activities. Seventy‐five TKA patients were recruited to this study and randomly assigned a posterior‐stabilized (PS), cruciate‐retaining (CR), or medial‐stabilized (MS) implant. Six months after surgery, patients performed five activities of daily living: level walking, step‐up, step‐down, sit‐to‐stand, and stand‐to‐sit. Mobile biplane X‐ray imaging was used to measure 6‐DOF knee kinematics and the center of rotation of the knee in the transverse plane for each activity. Mean 6‐DOF knee kinematics were consistently similar for PS and CR, whereas MS was more externally rotated and abducted, and lateral shift was lower across all activities. Peak‐to‐peak anterior drawer for MS was also significantly lower during walking, step‐up, and step‐down (p < 0.017). The center of rotation of the knee in the transverse plane was located on the medial side for MS, whereas PS and CR rotated about the lateral compartment or close to the tibial origin. The kinematic function of MS was more similar to that of the healthy knee than PS and CR based on reduced paradoxical anterior translation at low flexion angles and a transverse center of rotation located in the medial compartment. Overall, 6‐DOF knee joint motion for PS and CR were similar across all daily activities, whereas that measured for MS was appreciably different. The kinematic patterns observed for MS reflects a highly conforming medial articulation in the MS design.
