Evaluation and treatment of disorders of the infrapatellar fat pad.

Dragoo JL1, Johnson C, McConnell J.   Department of Orthopaedic Surgery, Stanford University, Palo Alto, CA, USA. jdragoo@stanford.edu Abstract The infrapatellar fat pad (IFP), also known as Hoffa’s fat pad, is an intracapsular, extrasynovial structure that fills the anterior kneecompartment, and is richly vascularized and innervated. Its degree of innervation, the proportion of substance-P-containing fibres and close relationship to its posterior synovial lining implicates IFP pathologies as a source of infrapatellar knee pain. Though the precise function of the IFP is unknown, studies have shown that it may [...]

Reducing blood loss in primary knee arthroplasty: a prospective randomised controlled trial of tranexamic acid and fibrin spray.

McConnell JS1, Shewale S, Munro NA, Shah K, Deakin AH, Kinninmonth AW.   Royal National Orthopaedic Hospital, Brockley Hill, Stanmore, Middlesex, England HA7 4LP, United Kingdom. jsm@doctors.net.uk Abstract A prospective, randomised controlled trial compared the effects of two medications intended to reduce blood loss from total knee arthroplasty. Patients were randomised to one of the following three treatment groups: 10mg/kg tranexamic acid at given at induction of anaesthesia, 10 ml of fibrin spray administered topically during surgery, or to a control group receiving neither treatment. Sixty six patients underwent elective [...]

Effects of vastus medialis oblique retraining versus general quadriceps strengthening on vasti onset.

Bennell K1, Duncan M, Cowan S, McConnell J, Hodges P, Crossley K.   Centre for Health, Exercise and Sports Medicine, School of Physiotherapy, University of Melbourne, Melbourne, Australia 3010. k.bennell@unimelb.edu.au Abstract PURPOSE: To compare the effects of vastus medialis oblique (VMO) motor control retraining (MCR) and quadriceps strengthening (QS) exercises on the onset timing of the medial (VMO) and lateral (vastus lateralis, VL) quadriceps muscle. METHODS: This single-blind randomized controlled trial involved 60 currently pain-free individuals with a history of anterior knee pain and delayed (>10 ms) onset of VMO relative to VL [...]

Efficacy of physiotherapy management of knee joint osteoarthritis: a randomised, double blind, placebo controlled trial.

Bennell KL1, Hinman RS, Metcalf BR, Buchbinder R, McConnell J, McColl G, Green S, Crossley KM.   Centre for Health, Exercise and Sports Medicine, School of Physiotherapy, University of Melbourne, Parkville, Victoria 3010, Australia. k.bennell@unimelb.edu.au Abstract OBJECTIVE: To determine whether a multimodal physiotherapy programme including taping, exercises, and massage is effective for kneeosteoarthritis, and if benefits can be maintained with self management. METHODS: Randomised, double blind, placebo controlled trial; 140 community volunteers with knee osteoarthritis participated and 119 completed the trial. Physiotherapy and placebo interventions were applied by 10 physiotherapists in private practices for 12 weeks. [...]

Physical therapy improves knee flexion during stair ambulation in patellofemoral pain.

Crossley KM1, Cowan SM, McConnell J, Bennell KL.   Centre for Health, Exercise and Sports Medicine, School of Physiotherapy, University of Melbourne, Victoria 3010, Australia. k.crossley@unimelb.edu.au Abstract PURPOSE: This study aimed to examine whether a physical therapy intervention, designed to reduce pain and improve the neuromotor control resulted in greater improvements in stance-phase knee flexion during stair ambulation in individuals with patellofemoral pain. The relationship between changes in stance-phase knee flexion and changes in pain, disability, and onset timing of individual vasti activity was also examined. METHODS: Forty participants aged 40 yr or [...]

Knee flexion during stair ambulation is altered in individuals with patellofemoral pain.

Crossley KM1, Cowan SM, Bennell KL, McConnell J.   Centre for Sports Medicine Research and Education, School of Physiotherapy, The University of Melbourne, Victoria 3010, Australia. k.crossley@unimelb.edu.au Abstract Reduced knee flexion is a logical gait adaptation for individuals with patellofemoral pain (PFP) to lessen the patellofemoral joint reaction force and minimise pain during stair ambulation. This gait adaptation may be related to the co-ordination of individual vasti components. PURPOSE: This study investigated the amount of stance-phase knee flexion in individuals with (n=48) and without (n=18) PFP using a [...]

Does the application of tape influence quadriceps sensorimotor function in knee osteoarthritis?

Hinman RS1, Crossley KM, McConnell J, Bennell KL.   Centrte for Sports Medicine Research and Education, School of Physiotherapy, University of Melbourne, Parkville, Victoria 3010, Australia. ranash@unimelb.edu.au Abstract OBJECTIVES: Using additional data from two previously reported studies, the aim was to determine the effects of immediate and short-term continuous (3 weeks) application of knee tape on quadriceps sensorimotor function in individuals with symptomatic knee osteoarthritis (OA). METHODS: A within-subjects study (n = 18) and a randomized controlled trial (n = 87) were performed using community volunteers. Therapeutic tape (patellar realignment and soft-tissue unloading) [...]

Efficacy of knee tape in the management of osteoarthritis of the knee: blinded randomised controlled trial.

Hinman RS1, Crossley KM, McConnell J, Bennell KL.   Centre for Sports Medicine Research and Education, School of Physiotherapy, University of Melbourne, Victoria, 3010, Australia. ranash@unimelb.edu.au Abstract OBJECTIVES: To test the hypotheses that therapeutic taping of the knee improves pain and disability in patients with osteoarthritis of the knee and that benefits remain after stopping treatment. DESIGN: Randomised single blind controlled trial with three intervention arms (therapeutic tape, control tape, and no tape) of three weeks’ duration and three week follow up. SETTING: Outcome assessment was performed in a university based laboratory. Taping interventions were [...]

Immediate effects of adhesive tape on pain and disability in individuals with knee osteoarthritis.

Hinman RS1, Bennell KL, Crossley KM, McConnell J.   Centre for Sports Medicine Research and Education, School of Physiotherapy, The University of Melbourne, Parkville, Victoria, Australia. Abstract OBJECTIVES: To evaluate the effects of two knee taping techniques, therapeutic tape and neutral tape, on pain and observed disability in symptomatic generalized knee osteoarthritis (OA). METHODS: Using a within-subjects study design, 18 participants were tested under three conditions in random order: untaped, wearing therapeutic knee tape and wearing neutral knee tape. Outcome measures included assessment of pain during each of four activities (using a visual analogue scale) and assessment [...]

Simultaneous feedforward recruitment of the vasti in untrained postural tasks can be restored by physical therapy.

Cowan SM1, Bennell KL, Hodges PW, Crossley KM, McConnell J.   Centre for Sports Medicine Research and Education, School of Physiotherapy, The University of Melbourne, 200 Berkeley Street, Carlton 3052, Australia. s.cowan@unimelb.edu.au Abstract BACKGROUND AND PURPOSE: Physical therapy rehabilitation strategies are commonly directed at the alteration of muscle recruitment in functional movements. The aim of this study was to investigate whether feedforward strategies of the vasti in people with patellofemoral pain syndrome can be changed by a physical therapy treatment program in a randomised, double blind, placebo controlled [...]
