“…Este resultado denota que a melhora do padrão de movimento pode melhorar o desempenho em testes de salto. Dix et al (2018) fizeram uma revisão sistemática e meta-análise com o objetivo de investigar a relação entre a força muscular do quadril e o valgo dinâmico das extremidades inferiores durante tarefas de movimento em mulheres assintomáticas. Os autores concluíram que embora a relação entre a força do quadril e o valgo dinâmico seja conflitante, a metanálise revelou que o VDJ foi consistentemente associado à força do quadril nas tarefas balísticas de perna única, mas não àquelas de perna dupla ou agachamento unipodal.…”

Objetivo: O valgo dinâmico de joelho é uma disfunção de movimento muito comum entre os atletas de vôlei, sendo fator de risco para lesões nessa articulação, o que poderia impactar negativamente a produção de potência muscular. Dessa forma, o objetivo deste estudo foi avaliar a influência da lateralidade do valgo dinâmico de joelho (uni- vs. bi-lateral) no desempenho do salto horizontal de atletas jovens de vôlei. Metodologia: Para tanto, foram selecionados 22 atletas de voleibol competitivos (oito do sexo masculino e 14 do feminino) que foram divididos nos grupos: valgo de joelho unilateral [VU - n=10, idade (anos): 13,7±1,4; massa corporal (kg): 56,9±12,9; estatura (cm): 163,5±9,2] e bilateral [VB - n=12, idade (anos): 13,6±2,3; massa corporal (kg): 52,8±13,8; estatura (cm): 165,91±8,65]. Os atletas realizaram três saltos horizontais e as distâncias horizontais obtidas (a melhor de três tentativas em cm) foram submetidas ao teste t para amostras independentes para verificar diferenças entre os grupos VU e VB. Resultados e discussão: Não foram observadas diferenças significativas entre os grupos VU vs. VB no teste de salto horizontal (VU: 166,2 ± 22,0 cm; VB: 162,6 ± 21,3 cm; p=0,703). Conclusão: Na casuística do presente estudo, a presença do valgo dinâmico de joelho/lateralidade não se mostrou um fator que pode influenciar no desempenho físico, particularmente da potência muscular de membros inferiores avaliada através de testes de salto horizontal, de atletas jovens de voleibol.

“…Strong hip and thigh muscles are thought to increase patellar stability by absorbing external hip and knee moments, preventing movement patterns associated with the LPD mechanism of injury (6). In other patient populations, hip muscle weakness has been associated with knee valgus (26), and quadriceps weakness with reduced knee exion on single leg landing (27,28). Higher quadriceps strength is also protects against patellofemoral joint cartilage loss and is associated with less pain and higher physical function, in people with patellofemoral osteoarthritis (29).…”

Background: lateral patellar dislocations mainly affect active teenagers and young adults. To help people recover, non-surgical exercise-based treatment is often recommended but the optimal exercise-based treatment is unknown. Currently, treatment outcomes after this injury are variable. Common problems include recurrent dislocation, reduced activity levels, and later surgery. A programme of intense leg resistance exercises, and dynamic exercises related to participants’ activity-related goals, has rationale, but has not been previously reported. In line with Medical Research Council guidance, this study aimed to assess the acceptability of a novel evidence-based exercise programme for adults after acute lateral patellar dislocation and the feasibility of future research evaluating this treatment.Methods: a single-group prospective study was conducted at the John Radcliffe Hospital, Oxford, UK. Participants were 16 years or older with an acute first-time or recurrent lateral patellar dislocation. Participants received up to six face-to-face, one-to-one, physiotherapy sessions, over maximum three months, and performed intensive home exercises independently at least three times per week. Strategies to increase exercise adherence were used. Primary objectives were to determine the number of eligible patients, the recruitment rate (proportion of eligible patients that provided written informed consent), participant adherence to scheduled physiotherapy sessions and self-reported adherence to prescribed exercise, and intervention acceptability to participants measured by attrition and a study-specific questionnaire. Data were analysed using descriptive statistics.Results: 15/22 (68%) patients with a lateral patellar dislocation were eligible. All eligible (100%) were recruited. 2/15 (13%) participants provided no outcome data, 2/15 (13%) provided partial outcome data, and 11/15 (73%) provided all outcome data. Questionnaire responses demonstrated high intervention acceptability to participants. Participants attended 56/66 (85%) physiotherapy sessions and 10/11 (91%) participants reported they ‘always’ or ‘often’ completed prescribed exercise. One participant redislocated their patella; another experienced knee pain or swelling lasting more than one week after home exercise on three occasions.Conclusion: the intervention appeared acceptable to adults after acute lateral patellar dislocation and future larger-scale research appears feasible. Future research should estimate feasibility outcomes with increased precision and assess participants’ willingness to be randomised to different treatments across multiple centres.Trial registration: ClinicalTrials.gov NCT03798483, registered January 10, 2019 https://clinicaltrials.gov/ct2/show/NCT03798483?term=INDEX-KD&draw=2&rank=1

“…Hence, previous studies conducted exercise intervention targeting the kinetic chain of DKV [4]. During closed chain activities, due to the interdependent of joint motions, excessive motions from one joint may overload subsequent tissues in the kinetic chain [5,6]. There are two types of kinetic chains related to DKV, which are top-down (i.e., proximal origins) and bottom-up (i.e., distal origins).…”

“…Regarding the top-down kinetic chain, the function of muscles and other soft tissues either at the trunk or hip joint may influence the occurrence of altered kinematic patterns at the subsequent distal joints [7]. It was shown that weakness of hip musculature was associated with greater knee valgus during single leg ballistic and single leg squat tasks [6]. Hip and trunk muscle strengthening are commonly recommended to modify lower limb kinematics such as excessive hip medial rotation and adduction during weight-bearing tasks and to treat and prevent injuries at distal joints of lower limbs [8].…”

The study investigated the influence of ankle strength and its range of motion (ROM) on knee kinematics during drop landing. Fifteen male and fifteen female university athletes with a normal range of dynamic knee valgus (DKV) (knee frontal plane projection angle: men = 3° to 8°, females = 7° to 13°) were recruited. They performed drop landing at height 30 cm and 45 cm with three-dimensional motion capture and analysis. Knee angles were compared at specific landing phases. Isokinetic ankle strength was tested at 60°/s angular velocity while the weight-bearing lunge test was conducted to evaluate ankle ROM. For males, strength for both plantarflexors and dorsiflexors were associated with knee kinematics at both heights (30 cm: r = −0.50, p = 0.03; 45 cm: r = −0.45, p = 0.05) during maximum vertical ground reaction force (MVGRF) phase. For females, ankle invertor strength and knee kinematics were associated at both 30cm (r = 0.53; p = 0.02,) and 45 cm landing heights (r = 0.49, p = 0.03), while plantarflexor strength and knee kinematics showed a significant association during initial contact (r = 0.70, p < 0.01) and MVGRF (r = 0.55, p = 0.02) phases at height 30 cm only. Male and female athletes with normal range of DKV showed a significant relationship between ankle strength and knee kinematics at specific landing phases. These relationships varied with increased landing height.
