This cadaveric investigation suggests that sonographic guidance can be used to inject the ACJ with a high degree of accuracy, and should be considered superior to palpation guidance. Clinicians should consider using sonographic guidance to inject the ACJ when diagnostic specificity is paramount or when otherwise clinically indicated.

US-guided knee injections that use a superolateral approach are very accurate in a cadaveric model, whereas the accuracy of palpation-guided knee injections that use the same approach is variable and appears to be significantly influenced by clinician experience. These findings suggest that US guidance should be considered when one performs knee injections with a superolateral approach that require a high degree of accuracy.

Stretching long has been commonplace in the training programs of recreational and competitive athletes. Its role in performance enhancement has been debated. This review discusses the literature concerning the effects of static, dynamic, and proprioceptive neuromuscular facilitation stretching on performance in three categories of sporting activity: strength- and power-dominant, speed- and agility-dominant, and endurance-dominant activities.
