A lack of lumbopelvic-hip complex (LPHC) stability is often associated with altered pitching mechanics, thus increasing pain and injury susceptibility. The single-leg squat (SLS) is a simple diagnostic tool used to examine LPHC stability.

To examine the relationship between trunk compensatory kinematics during the SLS and kinematics at foot contact during the windmill pitch.

Descriptive laboratory study.

Participants included 55 youth and high school softball pitchers (mean age, 12.6 ± 2.2 years; height, 160.0 ± 11.0 cm; weight, 60.8 ± 15.5 kg). Kinematic data were collected at 100 Hz using an electromagnetic tracking device. Participants were asked to complete an SLS on each leg, then throw 3 fastballs at maximal effort. Values of trunk flexion, trunk lateral flexion, and trunk rotation at peak depth of the SLS were used as the dependent variables in 3 separate backward-elimination regression analyses. Independent variables examined at foot contact of the pitch were as follows trunk flexion, trunk la stability.

Players and coaches should implement SLS analyses to determine their players’ risk for injury and compensation due to poor core stability.

Social media posts regarding ulnar collateral ligament (UCL) injuries and reconstruction surgerieshave increased in recent years.

To analyze posts shared on Instagram and Twitter referencing UCL injuries and reconstruction surgeries to evaluate public perception and any trends in perception over the past 3 years.

Cross-sectional study.

A search of a 3-year period (August 2016 and August 2019) of public Instagram and Twitter postswas performed. We searched for >22 hashtags and search terms, including

,

, and

. A categorical classification system was used to assess the sentiment, media format, perspective, timing, accuracy, and general content of each post. Post popularity was measured by number of likes and comments.

A total of 3119 Instagram posts and 267 Twitter posts were included in the analysis. Of the 3119 Instagram posts analyzed, 34% were from patients, and 28% were from providers. Of the 267 Twitter posts analyzed, 42% were from patients, and 16% were from providers. Although the mah an emphasis on education.

The majority of patients who post about their UCL injury and reconstruction on social media have a positive sentiment when discussing their procedure. However, negative sentiment posts have increased significantly over the past 3 years. Patient content revolves around rehabilitation and return to play. Although patient posts have declined over the past 3 years, provider posts have increased substantially with an emphasis on education.

The removal of all adherent muscle tissue from the hamstring graft during anterior cruciate ligament reconstruction (ACLR) is common practice. However, there is a paucity of research to justify this removal or evaluate its biological implications.

The purpose of this study was to (1) evaluate the histological characteristics of the myotendinous muscle tissue harvested from hamstring tendons, (2) compare the final diameter of the prepared graft before and after the removal of the remnant musculature, and (3) evaluate patients who were treated with and without preservation of the graft-adhered muscle. The hypothesis was that the adherent musculature of the graft would have cells that could contribute to graft incorporation and revascularization, assist in the proprioceptive capacity of the neoligament, and increase the graft’s diameter.

Cohort study; Level of evidence, 3.

We divided 84 patients into 2 groups group 1 underwent ACLR using hamstring tendon autograft with adherent musculature, and group 2 umuscles.

Preserving the muscle tissue on tendon grafts promoted a volumetric increase in the final autograft diameter and demonstrated biological and regenerative potential. Patients who underwent ACLR using the tendon with the muscle attached had better functional scores at 2-year follow-up as compared with patients treated using the tendon with the muscle removed.

The current techniques for medial malleolar osteotomy may lead to posterior tibial tendon injury and have a high rate of malunion.

To describe a novel partial step-cut medial malleolar osteotomy technique and evaluate its technical feasibility and its advantages compared with traditional methods.

Case series; Level of evidence, 4.

The novel technique consisted of osteotomy of the anterior one-third to two-thirds of the medial malleolus. A total of 19 ankles (18 patients) with osteochondral lesions of the talus underwent the novel osteotomy technique before osteochondral reconstruction. All patients were evaluated for more than 2 years. Radiographs were analyzed for postoperative displacement and malunion, and postoperative ankle function was evaluated according to the American Orthopaedic Foot & Ankle Society (AOFAS) ankle-hindfoot scale and the visual analog scale (VAS) for pain.

The partial step-cut osteotomy technique was able to provide adequate intra-articular exposure without disturbing the posterior tibial tendon. The 19 ankles healed at a mean of 7.3 ± 1.5 weeks (range, 6-12 weeks). There was slight incongruence in 4 ankles, with a displacement of 1.0 ± 0.1 mm proximally and 0.3 ± 0.1 mm medially. selleck kinase inhibitor The mean postoperative AOFAS and VAS scores improved compared with preoperatively, from 54.2 ± 12.1 to 84.6 ± 6.6 and from 6.4 ± 1.0 to 1.8 ± 1.3, respectively (

< .001 for both). No intraoperative tendon injuries were observed.

Results indicated that partial step-cut osteotomy is a reliable and effective method for providing enough exposure, avoiding displacement after reduction, and not disturbing the anatomic structures behind the medial malleolus.
