In patients with an acute Achilles tendon rupture, it has not been possible to determine the superiority of a single specific treatment modality over other treatments with respect to symptoms and function. When several pertinent treatment protocols are available for an injury, it is of interest to understand how other variables, such as age, sex, or physical activity level, affect outcome to better individualize the treatment. ⋯ The present study identified important possible predictors of outcome. Despite having a wide range of clinically relevant variables, the models had a limited ability to predict the final individual outcome. In general, the models appear to be better at predicting function than symptoms.

There have been no studies on the postoperative morphological characteristics of the restored labrum at different glenoid locations and its clinical relevance after arthroscopic Bankart repair with suture anchors. ⋯ Surgeons should be cautious of restoring labral height at the inferior glenoid location for successful arthroscopic Bankart repair. In addition, attention should be given to inserting the lowest suture anchor regardless of clinical significance.

Biological repair of cartilage lesions remains a significant clinical challenge because of the lack of natural regeneration and limited treatment options. ⋯ This study demonstrates a rapid, safe, and effective treatment for cartilage defects. For the patient population investigated, the clinical outcomes of the PJAC technique showed a significant improvement over baseline, with histologically favorable repair tissue 2 years postoperatively.

Comparative Study
Comparison of landing biomechanics between male and female dancers and athletes, part 1: Influence of sex on risk of anterior cruciate ligament injury.
The incidence of anterior cruciate ligament (ACL) injuries among dancers is much lower than among team sport athletes, and no clear disparity between sexes has been reported in the dance population. Although numerous studies have observed differences in landing biomechanics of the lower extremity between male and female team sport athletes, there is currently little research examining the landing biomechanics of male and female dancers and none comparing athletes to dancers. Comparing the landing biomechanics within these populations may help explain the lower overall ACL injury rates and lack of sex disparity. ⋯ These biomechanical findings may provide insight into the cause of the epidemiological differences in ACL injuries between dancers and athletes and the lack of a sex disparity within dancers.

Randomized Controlled Trial
Increased risk of osteoarthritis after anterior cruciate ligament reconstruction: a 14-year follow-up study of a randomized controlled trial.
The reported prevalence of radiological osteoarthritis (OA) after anterior cruciate ligament (ACL) reconstruction varies from 10% to 90%. Purpose/ ⋯ A 3-fold increased prevalence of OA was found after an ACL injury treated with reconstruction compared with the contralateral healthy knee. No differences in the prevalence of OA between the BPTB and quadrupled ST reconstructions were found. An initial meniscus resection was a strong risk factor for OA; the time between injury and reconstruction was not.
