Introduction: Reconstruction Surgery of the posterior cruciate ligament (PCL) has not yet been fully standardized, and associated rehabilitation protocols have not been clearly defined. The aim of this study is to report the results of a consecutive series of patients who underwent the same surgical technique for isolated PCL reconstruction and were submitted to the same specific rehabilitation protocol. A non-aggressive rehabilitation protocol which protects the graft from excess mechanical stress produces satisfying and reproducible clinical and laxity results in the knee.
Materials And Methods: Our series included 17 patients who underwent single bundle arthroscopic reconstruction of the PCL with an autologous quadriceps tendon graft and who followed the same non-aggressive rehabilitation protocol. All patients were followed up for an average of 30 months (range 12-60 months). The preoperative evaluation and the last follow-up included objective and subjective IKDC scores as well as the Tegner & Lysholm knee scales. The side to side laxity was measured radiologically with the Telos stress testing device. A statistical analysis was performed to compare preoperative and postoperative results.
Results: Preoperatively, no patients were classified as A or B on the IKDC objective score. At last follow-up visit, 88.2% of patients were classified as A or B. Average side to side anteroposterior laxity was 11.9 mm (range 8-18) in the preoperative evaluation and 3.8mm (range 1-7) in the final follow-up (p=0.01) The average subjective IKDC score was 37.7 before surgery and 74.7 at last follow-up (p< 0.01). The Tegner & Lysholm scores were significantly improved by surgery.
Discussion: Although the results are still less successful than ACL reconstruction, successful PCL reconstruction results were obtained with a standardized single bundle reconstruction technique and an adapted specific postoperative rehabilitation protocol. A non-aggressive rehabilitation protocol can limit postoperative mechanical stress on the graft.
Type Of Study: Retrospective Level IV.

This Extracorporeal Life Support Organization guideline describes early rehabilitation or mobilization of patients on extracorporeal membrane oxygenation (ECMO). The guideline describes useful and safe practices put together by an international interprofessional team with extensive experience in the field of ECMO and ECMO rehabilitation or mobilization. The guideline is not intended to define the delivery of care or substitute sound clinical judgment.

Background: Musculoskeletal pain (MSKP) disorders entail a significant burden for individuals and healthcare systems. The PainSMART-strategy has been developed aiming to reduce divergences between patients and healthcare practitioners in their understanding of MSKP by providing a shared basis for communication and to facilitate patients' self-management of MSKP. The objective of the PainSMART-project is to evaluate the effects of the PainSMART-strategy as an adjunct to usual physiotherapy management compared to usual physiotherapy management alone.

Background: Ankle sprain is a common clinical disease, which has the highest incidence rate among joint and ligament injuries. And acute ankle sprains can easily develop into chronic ankle instability, thereby increasing the difficulty of treatment. The current clinical guidelines for post-acute ankle sprains are still controversial.

Psychological interventions may make a valuable contribution to recovery following a mild traumatic brain injury (mTBI) and have been advocated for in treatment consensus guidelines. Acceptance and Commitment Therapy (ACT) is a more recently developed therapeutic option that may offer an effective approach. Consequently, we developed ACTion mTBI, a 5-session ACT-informed intervention protocol.

While patients with post-stroke aphasia recover over time, the dynamics of the underlying changes in the brain remain elusive. Neuroimaging work demonstrated that language recovery is a heterogeneous process, characterized by varying activation levels in several regions of the left-hemispheric language network and the domain-general bilateral multiple-demand network.
