“…For instance Sinclair et al, (2016) showed that a knee sleeve significantly reduced patellofemoral loading in athletes with patellofemoral pain and Gaasbeek et al (2007) showed that peak varus moment was significantly reduced when using a valgus knee brace in patients with medial compartment osteoarthritis. Excessive PTCF and PTS are considered to be one of the key mechanisms linked to the aetiology of knee pathologies in athletic populations (Ho et al, 2012). Therefore the key implication from this observation is that prophylactic bracing does not reduce the knee kinetic parameters that have been linked to the aetiology of knee pathologies.…”

“…PTCF was normalized by dividing the net PTCF by body mass (N/kg). PTCF during the stance (run and cut movements) and landing (jump movement) phases was estimated using knee flexion angle (kf) and knee extensor moment (KEM) through the biomechanical model of Ho, Blanchette, and Powers (2012). The sensitivity index of this model was validated by Sinclair et al (2015a, b), and this technique has been shown to sufficiently sensitive to detect differences in PTCF and PTS when wearing a knee brace vs. no brace (Sinclair et al, 2016).…”

ObjectiveTo investigate the effects of a prophylactic knee brace on knee joint kinetics and kinematics in netball specific movements. DesignRepeated measures; Setting: Laboratory; Participants: Twenty university first team level female netball players. Outcome measurementsParticipants performed three movements, run, cut and vertical jump under two conditions (brace and no-brace). 3-D knee joint kinetics and kinematics were measured using an eight-camera motion analysis system. Knee joint kinetics and kinematics were examined using 2 × 3 repeated measures ANOVA whilst the subjective ratings of comfort and stability were investigated using chi-squared tests. ResultsThe results showed no differences (p > 0.05) in knee joint kinetics. However the internal/external rotation range of motion was significantly (p < 0.05) reduced when wearing the brace in all movements. The subjective ratings of stability revealed that netballers felt that the knee brace improved knee stability in all movements. ConclusionsFurther study is required to determine whether reductions in transverse plane knee range of motion serve to attenuate the risk from injury in netballers.

“…Patellofemoral pain syndrome is the most frequently encountered chronic pathology of the knee in athletic populations [11,12] . Patellofemoral pain is linked to chronic overloading of the patellofemoral joint itself, during dynamic activities [13,14] . Such disorders can be debilitating, and patellofemoral pain syndrome has been identified as a pre-cursor to the advancement of osteoarthritis in later life [15] .…”

Purpose: The barbell squat is fundamental in strength and conditioning, with two principal variants; the back and front squat. Unfortunately, the propensity for injury is high particularly at the knee. The aim of the current investigation was examine the influence of front and back squat variations on patellofemoral joint load. Methods:Patellofemoral loads were obtained from thirty-five experienced male participants, who completed both back and front squats at 70% of 1 RM. Differences between squat conditions were examined using Bonferroni adjusted (P = 0.008) paired t-tests. Results:The results showed that significant differences (P < .008) in patellofemoral load were identified between both conditions with the highest load being experienced during the back squat exercise.Conclusions: Given the proposed relationship between the magnitude of the load experienced by the patellofemoral joint and associated injury pathology, the back squat appears to place lifters at greater risk from injury. Therefore, it may be prudent therefore for lifters who are predisposed to patellofemoral pain syndrome to utilize the front squat in their training.

Effects of high heel wear and increased weight on the knee during walking

Knee osteoarthritis (OA), a leading cause of disability, is more prevalent in women than men. Wearing high heeled shoes has been implicated as a potential contributing factor for the higher lifetime risk of osteoarthritis in women. This study tests the hypotheses that changes to knee kinematics and kinetics observed during high heeled walking increase in magnitude with increasing heel height and are accentuated by a 20% increase in weight. Fourteen healthy females were tested using marker-based gait analysis in combinations of footwear (flat athletic shoe, 3.8 cm and 8.3 cm heeled shoes) and weight (with and without 20% bodyweight vest). At preferred walking speed, knee flexion angle at heel-strike and midstance increased with increasing heel height and weight. Maximum knee extension moment during loading response decreased with added weight; maximum knee extension moment during terminal stance decreased with heel height; maximum adduction moments increased with heel height. Many of the changes observed with increasing heel height and weight were similar to those seen with aging and OA progression. This suggests that high heel use, especially in combination with additional weight, may contribute to increased OA risk in women.
