Very little information is available regarding the incidence, causative mechanisms, and expected duration of time lost after injuries to kickers (placekickers and punters) in American football. ⋯ Kicking athletes face a low risk of injury in professional American football. Injuries most commonly involve the lower extremities. Training and injury prevention efforts should reflect that punting is associated with different injuries than placekicking, and that older kickers take longer to recuperate than younger kickers after certain injuries.

Over 60 repair/reconstruction techniques have been described for the treatment of coracoclavicular (CC) ligament injuries. ⋯ Single-tunnel CC reconstruction with an autogenous hamstring tendon graft after a mean follow-up of 33 months (range, 18-47) appears to be a satisfactory means of treating acute Rockwood type IV, V, chronic type III, and painful nonunited distal clavicle fractures with CC separation.

Randomized Controlled Trial
Autologous chondrocyte implantation using the original periosteum-cover technique versus matrix-associated autologous chondrocyte implantation: a randomized clinical trial.
Autologous chondrocyte implantation (ACI) is frequently used to treat symptomatic defects of the articular cartilage. ⋯ There was no difference in the efficacy between the original and the advanced ACI technique 12 and 24 months after surgery regarding International Knee Documentation Committee, Tegner Activity Score, and Short Form-36; however, with respect to the Lysholm and Gillquist score, better efficacy was observed in the periosteal flap technique group.

Osteotomies have a role in the active patient with degenerative joint disease of the medial or lateral knee who, for reasons of age or activity level, is not yet a good candidate for prosthetic arthroplasty. Recognition and treatment of malalignment associated with ligamentous instability is essential if long-term good outcomes are to be expected from ligamentous reconstruction. ⋯ This review examines the use of osteotomies about the knee in the athletic patient. Indications, contraindications, preoperative planning, surgical techniques, and complications are reviewed.

The International Knee Documentation Committee Subjective Knee Form (IKDC SKF) is a patient-reported knee-specific outcome measure that has been shown to be a reliable, valid, and responsive measure for patients with a variety of knee conditions. Further testing is required to compare the reliability and responsiveness of the IKDC SKF to other commonly used patient-reported outcome measures for patients with articular cartilage lesions. ⋯ The reliability and responsiveness of the IKDC SKF is comparable with other commonly used patient-reported outcome measures for patients with articular cartilage lesions. The IKDC SKF is a suitable alternative to other commonly used knee-specific instruments for measuring symptoms, daily function, and level of symptom-free sports activity in patients undergoing articular cartilage surgery.
