Tibial spine fractures (TSFs) are relatively rare pediatric injuries. Postoperative arthrofibrosis remains the most common complication, with few studies having examined factors associated with its development. In conclusion, surgeons should be cognizant of arthrofibrosis risk in younger patients with concomitant ACL tears and traumatic injuries not resulting from athletics. Furthermore, postoperative immobilization in a cast should be avoided given the high risk of arthrofibrosis. Concomitant ACL injury is associated with a higher return to the operating room for MUA.   Click here to read the article.

The molecular mechanism of how femoroacetabular impingement (FAI) morphology leads to hip osteoarthritis (OA) is yet to be determined. Expression and location of inflammation-related molecules during early- and late-stage FAI have not been previously described. Moreover, characterization of intraarticular inflammation away from cam deformity as well as the nature of the adjacent synovial tissue has also not been extensively characterized. In conclusion, hip cartilage exhibits an osteoarthritic phenotype in patients with early FAI similar to what was observed in hip OA secondary to FAI. Severe synovitis was only evident in late-stage disease.   Click here to read the article.

Injuries to the hamstring complex most commonly involve the proximal musculotendinous junction of the long head of the biceps femoris (MTJ-BFlh). Nonoperative management of these injuries is associated with prolonged rehabilitation and high risk of recurrence. To our knowledge, the surgical management of acute MTJ-BFlh injuries has not been previously reported. In conclusion, surgical repair of acute MTJ-BFlh injuries enables return to preinjury level of sporting function with low risk of recurrence at short-term follow-up.   Click here to read the article.

Arthroscopic anterior cruciate ligament (ACL) reconstruction (ACLR) with a bone–patellar tendon–bone graft (BTB) is a reliable surgical option for the control of anterior knee laxity after ACL injury. The addition of a lateral extra-articular tenodesis (LET) may improve control of rotation knee laxity and improve short-term graft survival in high-risk patients. In conclusion, there were no significant differences in long-term patient-reported outcomes after ACLR with or without an LET. LET may increase the risk of lateral compartment osteoarthritis at long-term follow-up. There was a trend toward decreased graft failure risk with the addition of LET but this study was underpowered to assess this outcome.   Click here to read the article.

Preclinical studies suggest that for complete midsubstance anterior cruciate ligament (ACL) injuries, a suture repair of the ACL augmented with a protein implant placed in the gap between the torn ends (bridge-enhanced ACL repair [BEAR]) may be a viable alternative to ACL reconstruction (ACLR). In conclusion, BEAR resulted in noninferior patient-reported outcomes and AP knee laxity and superior hamstring muscle strength when compared with autograft ACLR at 2-year follow-up in a young and active cohort. These promising results suggest that longer-term studies of this technique are justified.   Click here to read the article.

Safe return to play (RTP) after anterior cruciate ligament (ACL) reconstruction is critical to patient satisfaction. Enhanced rehabilitation after ACL reconstruction with appropriate objective criteria for RTP may reduce the risk of subsequent injury. The cost-effectiveness of an enhanced RTP (eRTP) strategy relative to standard post-ACL reconstruction rehabilitation has not been investigated. In conclusion, the eRTP strategy in this study adds additional neuromuscular retraining and additional physician follow-up—as well as advanced testing goals upon which RTP is contingent—to traditional physical therapy. Our data suggest that these additions are cost-effective, even assuming only modest associated decreases in ACL graft failure. This study also determined that the only variable that had the potential to change the cost-effectiveness conclusion based on predetermined ranges was the additional cost of rehabilitation based on 1-way sensitivity analysis.   Click here to read the article.

Although a sex-based balance in US graduate medical education has been well-documented, a discrepancy remains in orthopaedic surgery. In orthopaedic sports medicine, the representation of women as team physicians has not previously been characterized. In conclusion, women comprise a minority of team physicians in select NCAA Division I collegiate and professional sports organizations. When compared with the composition of AOSSM orthopaedic surgeon membership, expected female orthopaedic surgeon representation varies between conferences and leagues with little statistical significance. Although efforts have been made to increase sex-based diversity in orthopaedic surgery, results of this study suggest that barriers affecting female orthopaedic surgeons as team physicians should be identified and addressed.   Click here to read the article.

*This podcast features Drs. Frances T. Sheehan and Camila Grant, and Cameron N. Fick from the NIH Clinical Center Rehabilitation Medicine. Developing bone is highly adaptable and, as such, is susceptible to pathological shape deformation. Thus, it is imperative to quantify if changes in patellofemoral morphology are associated with adolescent-onset patellofemoral pain, as a pathway to improve our understanding of this pain’s etiology. In conclusion, this study provides direct evidence that patellofemoral morphology is altered and influences maltracking in adolescents with patellofemoral pain, highlighting the multifactorial etiology of this pain. Neither morphology nor kinematics (measured during active flexion-extension) correlated with pain. Both increases and decreases in these parameters likely lead to pain, negating a direct linear correlation.   Click here to read the article.

Women are 2 to 9 times more likely to experience an anterior cruciate ligament (ACL) injury than men. Various hormones including relaxin, progesterone, and estrogen influence ACL strength. Oral contraceptives (OCs) alter these hormone levels; however, studies have yet to comprehensively compare different OCs’ effects on the ACL. In conclusion, OC formulations with higher progestin-to-estrogen ratios may be more protective for the ACL than formulations with lower ratios.   Click here to read the article.
