Purpose The purpose of this study was to identify if abnormal tibial alignment was a risk factor for lateral meniscus posterior root tears (LMPRT) in patients with acute anterior cruciate ligament (ACL) ruptures. Methods The medical charts of 200 patients treated for ACL ruptures between 2013 and 2016 were retrospectively reviewed and evaluated. MRI images and reports were assessed for concurrent meniscal tears. Radiographs were reviewed for tibia vara and tibial slope angles and MRI reports identifying lateral root tears were compared to intraoperative reports to determine accuracy. Multiple logistic regression models were constructed to identify potential risk factors for LMPRTs. Results Of the 200 patients reviewed, a total of 97 individuals with concurrent meniscal injuries were identified. In patients sustaining a concurrent meniscal injury, there was a 4% incidence of medial meniscus posterior root tears and a 10.3% incidence of LMPRTs. Patients sustaining an ACL injury with an LMPRT were found to have greater tibia vara angles (4.2 ± 1.0 vs. 2.9 ± 1.7; p = 0.024), increased tibial slopes (12.6 ± 1.5 vs. 10.7 ± 2.9; p = 0.034), and higher BMIs (27.3 ± 2.9 vs. 25.3 ± 5.9; p = 0.034) when compared to patients without meniscus tears. There was low agreement between MRI and arthroscopic findings (kappa rate = 0.54). Multiple logistic regression analysis demonstrated that a tibia vara angle > 3 was associated with a 5.2-fold increase (95% CI 0.99-27.01; p = 0.050), and a tibial slope > 12 with a 5.4-fold increase (95% CI 1.03-28.19; p = 0.046) in LMPRTs. Conclusions Patients with greater tibia varus angles, increased tibial slopes, and higher BMIs were found to have an increased risk of LMPRTs when sustaining an ACL rupture. There was a low rate of agreement between MRI and arthroscopy in identifying LMPRTs. In patients with ACL ruptures who have abnormal tibial alignment or increased BMI, physicians should be watchful for lateral meniscus posterior root tears. Level of evidence 3.
As anatomic total shoulder arthroplasty (aTSA) and reverse total shoulder arthroplasty (rTSA) become increasingly common, differences between the 2 procedures are of importance. The purpose of this study was to determine differences in acute pain levels between patients undergoing aTSA and rTSA. Sixty patients undergoing aTSA or rTSA were assessed for participation. The primary outcome was postoperative daily visual analog scale scores, which were initially collected for 4 days postoperatively. Secondary outcomes included opioid consumption, length of stay, and complications. Comparisons between the 2 groups were assessed using a multivariable analysis, which controlled for sex, age, body mass index, and type of anesthetic. A total of 57 patients consented and were analyzed. No significant differences were found in postoperative visual analog scale scores in the first 4 days following surgery or at 1 year postoperatively. Patients undergoing aTSA had a higher mean opioid requirement in the first 4 hours postoperatively (1.0±0.7 vs 0.4±0.6 morphine milligram equivalents, P <.01). Forty percent of patients undergoing shoulder arthroplasty were prescribed narcotics within the 3 months prior to surgery. Patients who were prescribed narcotics prior to surgery were more likely to continue to require narcotics at extended time periods postoperatively. Patients undergoing aTSA required more opioid medication in the immediate postoperative period. However, after 4 hours postoperatively, no significant differences in pain scores or opioid consumption were found. These findings suggest that patients undergoing aTSA or rTSA have similar postoperative pain profiles. Patients who are prescribed narcotics before shoulder arthroplasty are at an increased risk for postoperative opioid demand. [ Orthopedics . 2019; 42(2):e247–e252.]
Chronic instability of the sternoclavicular (SC) joint is a challenging clinical problem, particularly in a patient population for which nonoperative forms of treatment prove ineffective. Patients present after experiencing recurrent subluxation events and subsequent pain, which commonly result in increasing functional limitation. Recurrent SC joint instability of this nature can lead to damage of the SC joint cartilage and bone, and in cases of posterior subluxation or dislocation, damage to mediastinal structures. While the precise treatment algorithm requires tailoring to individual patients and their respective pathologies, we have demonstrated successful outcomes in correcting chronic SC joint instability by means of SC joint reconstruction with semitendinosus allograft, SC joint capsular reconstruction, and, in cases of arthritic damage, resection of a small portion of the degenerative component of the medial clavicle. The purpose of this Technical Note is to describe a technique that uses a semitendinosus allograft to stabilize the SC joint combined with a capsular reconstruction in patients who have previously failed nonoperative treatment methods.
