ReviewPlatelet-rich plasma (PRP) to treat sports injuries: evidence to support its use.
Tissue repair in musculoskeletal lesions is often a slow and sometimes incomplete process. In sports patients or professional athletes, the impact of musculoskeletal lesions on life and work is great, and the fast recovery of full efficiency and return to competition is of primary importance. The clinical improvement offered by available treatments is not always sufficient for highly demanding patients to return to their previous level of activity. ⋯ The aim of this review is to analyse the existing published studies to look for scientific evidence in preclinical studies or in the results obtained through PRP application in humans that supports the efficacy of PRP and its use for the treatment of tendinous, ligamentous, cartilaginous and muscular injuries. The analysis of the literature shows promising preclinical results but contradictory clinical findings for the treatment of sport injuries. High-quality studies are required to confirm these preliminary results and provide scientific evidence to support its use.

Comparative StudyAnatomical reconstruction of the anterior inferior tibiofibular ligament for chronic disruption of the distal tibiofibular syndesmosis.
The purpose of this study was to investigate the clinical results of anatomical reconstruction of anterior inferior tibiofibular ligament (AITFL) for the chronic tibiofibular syndesmotic disruption after typical pronation external rotation (PER) stage 4 injury. ⋯ The procedure, which can achieve anatomical reconstruction of the AITFL easily, seems to be one possible treatment for chronic disruption of the distal tibiofibular syndesmosis after PER stage 4 injury including avulsion fracture of the posterior malleolus, which is most common in this type of injury.

Arthroscopic patellar reinsertion of the MPFL in acute patellar dislocations.
The objective of this study was to evaluate the mid-term results of a new technique for the arthroscopic repair of MPFL after an acute patellar dislocation (APD). ⋯ When the MPFL is avulsed from the patella, the proposed technique has the advantage of restoring tension of the ligament through reattachment at the patellar border with two trans-patellar sutures. The full-arthroscopic approach has the advantage of being less invasive and having a shorter recovery time.

Quadriceps muscle activation and radiographic osteoarthritis following ACL revision.
Quadriceps strength and activation may play an important role in the recovery from ACL revision surgery. The purpose of this study was to describe quadriceps strength and central activation ratio (CAR) and correlate with radiographic findings in patients with ACL revision surgery. ⋯ Bilateral quadriceps central activation deficits and radiographic osteoarthritis are evident in patients with revision ACL reconstruction.

Patellar shape can be a predisposing factor in patellar instability.
Predisposing factors to objective patellar instability include trochlear dysplasia, patella alta, patellar tilt and elevated tibial tuberosity-femoral groove distance. The shape of the patella is classically not considered a predisposing factor. Anomalies of dynamic and static factors, including excessive patellar height, tibial tubercle lateralisation or trochlear dysplasia, may influence the development of the patella. ⋯ Increased lateral stresses may produce a Wiberg type C patella, with a hypoplastic medial facet and a more developed lateral facet. Unbalance between dynamic medial and lateral stabilisers may act as an additional factor. A rehabilitation program aiming to reduce this unbalance may decrease the incidence of type C patella in young patients.
