Moreover, these patients were significantly more likely than controls to develop concomitant patellofemoral osteoarthritis (OA) in the index knee and tibiofemoral
OA in the contralateral, nonoperated knee, Dr.
We defined disease progression as either a reduction in the tibiofemoral
joint space by at least 2 mm or total replacement of either knee during the 5-year follow up," Dr.
OA was found in 48% of operated knees, 27% of contralateral knees, and 9% of control knees.
9) Revisions were performed for infection (two cases), tibiofemoral
instability (one case), patellar problems (three cases), and excessive poly wear (one case).
The study showed that a greater internal hip abduction moment--or torque generated by the body during walking--protected against medial tibiofemoral
osteoarthritis (OA) progression in the ensuing 18 months in patients with knee OA.
8) Patellofemoral stability is also dependent on limb alignment, which includes varus or valgus tibiofemoral
alignment as well as rotational variances in femoral version.
SAN DIEGO -- Patients who underwent meniscectomy had a 10- to 18-fold increased likelihood of developing tibiofemoral
osteoarthritis in the operated knee at follow-up of 15-22 years, compared with a group of controls, results from a large Swedish study demonstrated.
Joint space was measured radiographically at the tibiofemoral
joint and assessed by digital image analysis.
contact point moves anteriorly due to the posterior subluxation of the tibia and can lead to increased contact pressures in the medial and patellofemoral compartments, eventually resulting in degenerative changes in these areas.
Standardized techniques for measuring joint space width (JSW) in the medial tibiofemoral
(TF) compartment, taken from carefully acquired radiographs, have become accepted for quantifying changes in TF articular cartilage thickness in knee OA.
In the medial tibiofemoral
compartment, bone attrition and bone marrow edema scores greater than 0 were significantly associated with knee pain (P < .
The investigational drug sprifermin significantly increased cartilage thickness in the tibiofemoral
joint of patients with knee osteoarthritis in the initial 2-year results of the ongoing FORWARD trial.
