Long term improvement of knee osteoarthritis after injection of single high/very high volume of very pure PRP: A retrospective analysis of patients optimally managed in dedicated centers.

Introduction: PRP is gaining increasing interest for pain relief and improvement of joint function in patients with knee osteoarthritis (KOA) but practices and results remain heterogeneous limiting its adoption as standard of care. Current international recommendations are to collect real-life evidence of efficacy with a systematic monitoring of PRP quality and patients' outcomes. We aimed to analyze the response of patients presenting KOA and treated with standardized PRP injection in routine care.

Overuse injuries in high school runners: lifetime prevalence and prevention strategies.

Objective: To evaluate lifetime prevalence and risk factors for overuse injuries in high school athletes currently participating in long-distance running and provide recommendations for injury prevention strategies.

Design: Retrospective study design.

Setting: Twenty-eight high schools in the San Francisco Bay Area.

Patellofemoral pain syndrome.

Patellofemoral pain (PFP) syndrome is a frequently encountered overuse disorder that involves the patellofemoral region and often presents as anterior knee pain. PFP can be difficult to diagnose. Not only do the etiology, diagnosis, and treatment remain challenging, but the terminology used to describe PFP is used inconsistently and can be confusing.

Improvement of gait in a stroke patient. A 7-year longitudinal study.

Purpose: To report on the gait improvement obtained in a stroke patient after applying three treatments for spastic equinus varus foot: botulinum toxin injection (BTI), tibial nerve neurotomy (TNN), and orthopaedic surgery (triple arthrodesis), during a 7-year longitudinal follow-up period.

Method: A quantified analysis of a stroke patient's gait was performed on a Gaitrite walking mat before and after applying BTI 3 years, TNN 4 years and orthopaedic surgery 7 years after the stroke.

Results: After the three treatments, the spasticity disappeared, the range of ankle motion improved and voluntary command of the tibialis anterior became possible.

Orthotic fitting improves gait in a patient with generalized secondary dystonia.

Objective: To determine whether an orthotic fitting improved gait in an adult patient presenting with generalized secondary dystonia.

Patient: The patient had stance and gait disturbances associated with pain, ankle instability and fatigability. Clinical examination showed the presence of dystonia in the foot and ankle, along with equinovarus foot, mainly on the left side.

Changes in postural control in hemiplegic patients after stroke performing a dual task.

Objective: To determine the effects of an attentional task on hemiplegic patients' postural control performances.

Design: Retrospective study.

Setting: Department of physical and rehabilitation medicine at a university hospital.

Gait recovery in a distal spinal muscular atrophy patient wearing a patellar tendon-bearing orthosis and orthopaedic shoes.

Objective: To illustrate that a patient with distal spinal muscular atrophy can recover gait with a combination of orthoses and orthopaedic shoes.

Subject: A 28-year-old man with distal spinal muscular atrophy affecting only the distal muscles of the lower limbs. Clinical examination showed a bilateral pes cavus with a varus and a 90 degrees equinus of the ankle joint.

Does fascicular neurotomy have long-lasting effects?

Objective: To determine whether fascicular neurotomy has long-lasting effects on spasticity.

Design: We present 4 clinical cases and a critical analysis of the literature.

Patients: This is a retrospective study on 4 patients referred to our department for spastic equinovarus foot deformity.
