Fasciotomy for Deep Posterior Compartment Syndrome in the Lower Leg: A Prospective Study
Conclusion: Fasciotomy was beneficial in 71% of patients with dp-CECS in the lower leg; 47% of study patients experienced a good to excellent outcome. Outcomes were stable in the long term. Persistent complaints were often caused by other untreated conditions. (Source: The American Journal of Sports Medicine)

Effects of Pulsed Electromagnetic Fields on Return to Sports After Arthroscopic Debridement and Microfracture of Osteochondral Talar Defects: A Randomized, Double-Blind, Placebo-Controlled, Multicenter Trial
Conclusion: PEMF does not lead to a higher percentage of patients who resume sports or to earlier resumption of sports after arthroscopic debridement and microfracture of talar OCDs. Furthermore, no differences were found in bone repair between groups. Registration: Netherlands Trial Register NTR1636. (Source: The American Journal of Sports Medicine)

Susceptibility to Hamstring Injuries in Soccer: A Prospective Study Using Muscle Functional Magnetic Resonance Imaging
Conclusion: This was the first study to assess the causal relation between the intramuscular recruitment pattern and the risk of sustaining an index or secondary hamstring strain. Changes in intermuscular interplay seem to significantly increase the risk of sustaining index hamstring injuries in male amateur soccer players. Inadequate eccentric muscle endurance could be associated with an increased risk of sustaining a recurring hamstring injury. (Source: The American Journal of Sports Medicine)

Graft Bending Angle at the Intra-articular Femoral Tunnel Aperture After Single-Bundle Posterior Cruciate Ligament Reconstruction: Inside-Out Versus Outside-In Techniques
Conclusion: The graft bending angles in single-bundle PCL reconstruction were more acute in the sagittal and axial planes with the IO compared with the OI technique, but there was no difference in the coronal plane. In addition, femoral tunnel lengths did not differ significantly in patients who underwent OI and IO single-bundle PCL reconstructions. Although further biomechanical studies are needed to evaluate the effect on graft failure of a <10° difference in graft bending angle, the small magnitude of this difference would likely have little adverse effect on graft survival.

Importance of Donor Chondrocyte Viability for Osteochondral Allografts
Conclusion: Viable chondrocytes in OCAs at the time of transplantation are primarily responsible for maintenance of donor articular cartilage health in the long term. Clinical Relevance: Optimizing chondrocyte viability in all aspects of OCA transplantation—including procurement, processing, storage, transportation, and surgical implantation—needs to be a primary focus for OCA clinical use.

Autologous Bone Plug Supplemented With Autologous Chondrocyte Implantation in Osteochondral Defects of the Knee
Conclusion: The OsPlug technique shows significant improvement of functional outcome for up to 5 years in patients with high-grade osteochondritis dissecans or osteochondral defect. This is the first report describing association of bone graft integration with functional outcome after such a procedure. It also demonstrates histologic evidence of integration of the repair cartilage with the underlying bone graft. (Source: The American Journal of Sports Medicine)

Survivorship of Meniscal Allograft Transplantation in an Athletic Patient Population
Conclusion: While reporting low reoperation and revision rates, this investigation indicates that 22% of patients with MAT were unable to return to military duty due to persistent knee limitations at short-term follow-up. Increased surgical experience may decrease rates of failure after MAT. Careful patient selection and referral to subspecialty-trained, higher-volume surgeons should be considered to optimize clinical outcomes after MAT. (Source: The American Journal of Sports Medicine)

Changes in Knee Osteoarthritis, Symptoms, and Function After Anterior Cruciate Ligament Reconstruction: A 20-Year Prospective Follow-up Study
Conclusion: The prevalence of radiographic TF and PF OA was 42% and 21%, respectively. A significantly higher prevalence of TF OA was found for subjects with combined injuries compared with those who had isolated ACL injury. The majority of the subjects were stable radiographically over the 5 years between follow-ups. A statistically significant deterioration in symptoms and function was noted, but the mean changes were of questionable clinical importance. (Source: The American Journal of Sports Medicine)

The Involvement of the Anterolateral Ligament in Rotational Control of the Knee
Conclusion: The ALL is involved in rotational control of the knee at varying degrees of knee flexion and during a simulated pivot shift. Concomitant to an ACL or ITB transection, sectioning the ALL further increased rotational laxity. Clinical Relevance: This laboratory study demonstrated that the ALL provides rotational control of the knee in combination with the ACL and/or ITB. (Source: The American Journal of Sports Medicine)

Distribution of Force in the Medial Collateral Ligament Complex During Simulated Clinical Tests of Knee Stability
Conclusion: The POL provides complementary load bearing to the ACL near extension in response to combined torques, which capture key components of the pivot-shift examination. The sMCL resists the valgus component of the maneuver alone, a loading pattern unique from those of the POL and ACL. The dMCL is not loaded during clinical tests of rotational knee stability in the ACL-competent knee. Clinical Relevance: Both the sMCL and POL work together with the ACL to resist combined moments, which form key components of the pivot-shift examination.

The Use of Sonographically Guided Botulinum Toxin Type A (Dysport) Injections Into the Tensor Fasciae Latae for the Treatment of Lateral Patellofemoral Overload Syndrome
Conclusion: An injection of BT into the TFL, combined with physical therapy, resulted in a significant improvement of symptoms in patients with LPOS, which was maintained at 5-year follow-up. This may result from reduced lateral TFL/ITB tension or to an increase in GMed activity in response to inhibition of the TFL. (Source: The American Journal of Sports Medicine)
