Quadriceps tendon tears are rare in professional American football players, and they usually occur from eccentric load on the extensor mechanism. Prodromal symptoms and predisposing factors are usually absent. Even with timely surgical repair, there is a low rate of return to play in regular-season games. There is a trend toward early draft rounds for those who successfully return to play.

Patellar tendon ruptures can occur in otherwise healthy professional football players without antecedent symptoms or predisposing factors. The most common mechanism of injury is eccentric overload. Close attention should be paid to stability examination of the knee given the not uncommon occurrence of concomitant ACL injury. Although this is usually a season-ending injury when it occurs in isolation, acute surgical repair generally produces good functional results and allows for return to play the following season. Players chosen earlier in the draft are more likely to return to play.

Incomplete UCL injuries in professional baseball players can be successfully treated nonoperatively in the majority of cases. Pitchers are more likely to have complete tears leading to surgery. MRI grading of UCL injuries can help predict RTP and the need for surgery.

On the basis of currently available data, double-row rotator cuff repair is not cost-effective for any size rotator cuff tears. However, variability in the values for costs and probability of retear can have a profound effect on the results of the model and may create an environment in which double-row repair becomes the more cost-effective surgical option. The identification of the threshold values in this study may help surgeons to determine the most cost-effective treatment.

This model suggests that hamstring autograft ACL reconstruction is the most cost-effective method of surgery for the average patient with ACL deficiency. However, specific clinical scenarios that change postoperative probabilities of the different complications may sway surgeons to choose either allografts or BPTB. Cost-effectiveness analysis is not intended to replace individual clinician judgment but rather is intended to examine both the effectiveness and costs associated with theoretical groups undergoing specific multifactorial decisions.

: Prophylactic fixation with a cephalomedullary nail was not found to be cost-effective for the average older woman who sustained a hip fracture. However, it may be appropriate for select patient populations. The study supports the need for basic science and clinical trials investigating the effectiveness of prophylactic fixation for patient populations at higher lifetime risk for contralateral hip fracture.
