Distal Biceps Femoris Tendon Tear in an Active-Duty Soldier: A Case Report and Review of the Literature
We present a case report of an active-duty soldier who sustained an intratendinous rupture isolated to the long head of the biceps femoris, as well as a summary of the available evidence on this subject matter. A combined end-to-end repair with partial tenodesis to the intact short head allowed the patient a near-full return to military duties at 5 months postoperatively. Surgery combined with diligent, supervised rehabilitation may be effective in returning patients with intratendinous distal biceps femoris tendon tears to athletic lifestyles.

Predictors of Disparities in Patient-Reported Outcomes before and after Arthroscopic Meniscectomy
J Knee Surg DOI: 10.1055/s-0042-1743229The purpose of this study is to identify predictors of disparities in patient-reported outcome measures (PROMs) before and after arthroscopic meniscectomy. Knee injury and Osteoarthritis Outcome Score (KOOS) was used in this study. All patients who underwent single-knee arthroscopic meniscectomy from January 2012 to March 2018 performed by a single surgeon at an academic safety-net hospital were identified. We excluded patients who had undergone ipsilateral previous knee surgery, bilateral meniscectomy, or concomitant ligament, cartilage, or osteotomy procedures, and those with severe...

Friction Syndromes of the Knee
J Knee Surg DOI: 10.1055/s-0042-1743222The knee is a complex joint with many fascial and ligamentous interactions. The movement in multiple planes makes the knee a prime site for friction syndromes, especially in active individuals. The most common friction syndrome is the iliotibial band friction syndrome. This occurs commonly in runners and cyclists and can be diagnosed clinically in a patient with lateral knee pain during activity. The anterior fat pads of the knee can also be the site of friction syndromes, most often in the Hoffa fat pad. Edema here can be located in the superolateral aspect of the fat pad when associ...

Evaluation and Management of Intra-Articular Tumors of the Knee
J Knee Surg DOI: 10.1055/s-0042-1743223Intra-articular tumors of the knee are most commonly benign. Overall, this is a relatively rare clinical presentation. The differential diagnosis includes pigmented villonodular synovitis, synovial chondromatosis, lipoma arborescens, synovial hemangioma, and very rarely primary sarcoma (synovial sarcoma being the most common). The clinical presentation for these conditions is usually non-specific, but radiographic and advanced imaging findings are able to differentiate some of these tumors. It is essential to obtain and send tissue specimens to pathology for histologic analysis to rul...

Lateral Patellar Facetectomy Reduces the Incidence of Anterior Knee Pain in Patellar Resurfaced Total Knee Arthroplasty
J Knee Surg DOI: 10.1055/s-0042-1743226Lateral patellar facet impingement (LPFI) can cause anterior knee pain (AKP) after patellar resurfaced total knee arthroplasty (TKA). Recently, lateral patellar facetectomy (LPF), which has been used for LPFI, has been performed during primary TKA, providing good clinical outcomes. However, the effect of LPF on AKP in primary patellar resurfaced TKA has not been sufficiently studied. The purpose of this study was to examine the effect of LPF on the development of AKP in patellar resurfaced TKAs with minimum follow-up of 3 years. This retrospective cohort study included 84 knees of 66 ...

Management of Pathologic Fractures around the Knee: Part 2 —Proximal Tibia
J Knee Surg DOI: 10.1055/s-0042-1743225Metastatic disease affecting the proximal tibia is rarer than disease affecting the femur; however, it presents unique challenges that the orthopaedic surgeon must address to ensure successful outcomes and return the patient to an ambulatory status. The essential workup for evaluating and treating these patients is addressed briefly in this review as a summary of the information is provided in part 1 of this series. Part 2 of this series will focus on the surgical treatment of these lesions, which can be complex and is not as well described in the literature. Procedures ranging from o...

Management of Primary Aggressive Tumors of the Knee
J Knee Surg DOI: 10.1055/s-0042-1743221Primary bone sarcomas and aggressive benign bone tumors are relatively rare. It is essential to recognize features that are concerning for these aggressive tumors based on a patient's history, physical exam, and radiographs. Physicians and other health care providers should have a high suspicion for these tumors and promptly refer these patients to orthopaedic oncologists. A multidisciplinary, team-based approach is required to obtain an accurate diagnosis and provide comprehensive care. This review discussed the appropriate work-up, biopsy principles, relevant peri-operative medical ...

Comparison of Acute-Phase Pain Intensity, Pain Trajectory, and the Number of Analgesics Administered between Total and Unicompartmental Knee Arthroplasties
This study suggests that pain characteristics observed during the acute phase differ between total and unicompartmental knee arthroplasties. Postoperative pain should be managed, and rehabilitation should be provided at similar levels after the second postoperative day in total and unicompartmental knee arthroplasty patients.

Poor Accuracy of Intraoperation Medial Proximal Tibial Angle Measurement Compared to Alignment Rod Methods in Open-Wedge High Tibial Osteotomy for Medial Knee Osteoarthritis
This study was retrospective case series. This study involved 152 patients undergoing OWHTO for primary medial osteoarthritis. Alignment rod or MPTA measurement board was used as an index of optimal correction in OWHTO. Alignment rod was used from October 2013 to May 2017, and MPTA measurement board was used from June 2017 to April 2020. The correction using an alignment rod was that the weight-bearing line ratio (WBLR) passed through 62.5% of the tibial plateau which was defined as Fujisawa's point under intraoperative fluoroscopy (A rod group). The correction using MPTA measurement board was aligning the intraoperative M...

Early Superior Clinical Outcomes in Robotic-Assisted TKA Compared to Conventional TKA in the Same Patient: A Comparative Analysis
This study is a retrospective review that assesses clinical outcomes of 36 patients who underwent a primary RA-TKA and had undergone a prior contralateral M-TKA. All surgeries were performed by a single surgeon at the same institution. Patients were assessed for differences in hospital length of stay, improvement in pre- versus postoperative range of motion, Knee Injury and Osteoarthritis Outcome Score (KOOS), and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores. Student's t-test and Fisher's exact test were utilized to detect significant differences. Patient demographics showed a mean age of 64.5, ...

Obesity, Comorbidities, and the Associated Risk among Patients Who Underwent Total Knee Arthroplasty in Alberta
In this study, we examined whether obesity along with other comorbidities is associated with peri/postoperative complications in patients who underwent primary unilateral TKA in Alberta, Canada. A retrospective secondary analysis was performed on data extracted from data repository of patients (n = 15,151) who underwent TKA between 2012 and 2016. The sample was divided into five groups based on body mass index (BMI) classification developed by the World Health Organization. The associations between dependent variable (presence or absence of a complication or comorbidity) with the independent variables (year of surgery,...
