Despite advancements in surgical techniques, the recurrence rate of anterior cruciate ligament (ACL) rupture after reconstruction remains between 2% and 20%. An increased posterior tibial slope (PTS) is associated with higher ACL rupture and reconstruction failure rates. In conclusion, ACW-HTO combined with ACL reconstruction shows promising long-term outcomes, significantly reducing PTS and improving knee stability and function with an acceptable complication rate.

Focal cartilage lesions are commonly associated with anterior cruciate ligament injuries. The long-term effect of these lesions on patient-reported outcomes after anterior cruciate ligament reconstruction (ACLR) remains unclear. In conclusion, patients with concomitant partial- or full-thickness cartilage lesions reported significantly worse outcomes in all KOOS subscales 10 years after ACLR as compared with patients without cartilage lesions.

Emerging evidence suggests that anterior cruciate ligament (ACL) ruptures can restore ACL fiber continuity. The relationship between ACL continuity on magnetic resonance imaging (MRI) (sign of ACL healing) and outcomes >5 years after an acute ACL rupture has not been investigated. ACL continuity on 5-year MRI may be associated with worse patient-reported outcomes at 11 years after an ACL injury compared with early or delayed ACLR. Click here to read the article.

Sagittal-plane slope-reducing high tibial osteotomy (HTO) can reduce the risk of anterior cruciate ligament (ACL) injury in knees with a high posterior tibial slope. The biomechanical effect of slope-reducing HTO on tibiofemoral kinematics and force carried by the ACL remains less well understood. In conclusion, slope-reducing HTO decreased ACL force linearly by reducing ATT with compression and also by decreasing coupled ITR with combined compression and valgus.

The best management of irreparable rotator cuff tears remains uncertain, with multiple new techniques introduced over the past 2 decades. Two options for treatment are arthroscopic debridement and biceps tenotomy, or the subacromial balloon spacer. Early trial results favored the former option, but the 2-year results have not yet been reported. In conclusion, participants continued to show better results in the debridement-only group compared with the group who had debridement with the InSpace balloon. Therefore, we do not recommend the subacromial balloon spacer for the treatment of irreparable rotator cuff tears. Click here to read the article.

In the presence of anterior glenoid bone loss (aGBL), options for bony glenoid augmentation include Latarjet procedures and free bone block transfers. Bone graft placement is challenging, and malposition causes complications, such as recurrent instability or osteoarthritis. In conclusion, in the presence of aGBL, flush bone block placement restores osteochondral glenohumeral stability, while a 1-mm medialized bone block fails to increase stability. Bone block lateralization of 1 mm provides higher stability but is associated with humeral head lateralization. Click here to read the article.
Medial meniscal repair performed at the time of primary anterior cruciate ligament reconstruction (ACLR) has been shown to be significantly associated with subsequent surgery, and subsequent surgery has been associated with increased Knee injury and Osteoarthritis Outcome Score (KOOS) pain score and decreased patient satisfaction. In conclusion, successful medial meniscal repair performed at the time of primary ACLR decreased clinically significant knee pain 10 years postoperatively. However, the mediating effect of subsequent surgery was significant and diminished the overall contribution of medial meniscal repair in decreasing the likelihood of KOOS pain. Continued efforts should be made to decrease the likelihood of subsequent surgery after medial meniscal repair performed at the time of primary ACLR. Click here to read the article.

Tobacco use is a known modifiable risk factor for postoperative complications and revision surgery after anterior cruciate ligament reconstruction (ACLR). Previous studies focus on tobacco as a broad categorization of traditional smoking, smokeless tobacco, and other forms of nicotine use. It is unclear if differences in the type of nicotine used lead to similar adverse outcomes after ACLR. In conclusion, smokeless tobacco use was associated with an increased risk of medical complications, ED utilization, and subsequent procedures compared with nonuser controls and traditional smokers. These findings highlight the importance of considering specific forms of tobacco use in preoperative screening for patients undergoing ACLR. Click here to read the article.

Anterior cruciate ligament (ACL) injury is one of the most severe injuries for athletes. It is important to identify risk factors because a better understanding of injury causation can help inform athletes about risk and increase their understanding of and motivation for injury prevention. In conclusion, the anatomic factors that we investigated had a weak or no association with risk for an index noncontact ACL injury. Increased static knee valgus was associated with an increased risk for noncontact ACL injury, in particular for secondary injury. Furthermore, hyperextension of the knee was a risk factor for secondary ACL injury. Click here to read the article.
Osteochondritis dissecans (OCD) of the knee is a focal idiopathic alteration of subchondral bone and/or its precursor with risk for instability and disruption of adjacent cartilage. Treatment options focused on preventing premature osteoarthritis vary depending on multiple patient and lesion characteristics, including lesion mobility. In conclusion, age, effusion, and loss of motion can predict knee OCD lesion mobility at the time of arthroscopy. Education about lesion mobility can help with surgical planning and patient and family counseling. Click here to read the article.
