Correction of Sagittal Deformity with Bone Resection and Soft Tissue Releases
J Knee Surg DOI: 10.1055/a-2131-6957Fixed flexion deformities (FFDs) present several unique challenges in total knee arthroplasty (TKA) and require careful consideration to achieve optimal outcomes. FFD alters normal knee biomechanics and increases energy expenditure (1). They may be attributed to both bony deformities and fibrosed soft tissues, which must be addressed in stepwise fashion at the time of surgery. A literature review was conducted utilizing keywords “fixed flexion deformity TKA.” This review article aims to discuss the anatomy and pathology, preoperative evaluation, classification system, surgical techni...

Engaging Patients and Caregivers to Develop a Patient-Centered Agenda for Comparative Effectiveness Research Focused on the Treatment of Complex Knee Problems
J Knee Surg DOI: 10.1055/s-0043-1772608Complex articular cartilage loss in the knee is being diagnosed more frequently and earlier in life, and patients are faced with major decisions regarding invasive surgical interventions at increasingly younger ages. There is a critical unmet need to provide patient-centered comparative effectiveness research for the hundreds of thousands of patients faced with these treatment decisions each year. Toward filling the need, we developed the Patient AdvisoR Team iN Orthopaedic ReSearch (PARTNORS) program. We recruited a diverse group of patients and caregivers with lived experiences in d...

Using a Markerless Motion Capture System to Identify Preinjury Differences in Functional Assessments
J Knee Surg DOI: 10.1055/s-0043-1772238Functional assessments identify biomechanical issues which may indicate risk for injury and can be used to monitor functional recovery after an injury or surgery. Although the gold standard to assess functional movements is marker-based motion capture systems, these are cost prohibitive and have high participant burden. As such, this study was conducted to determine if a markerless motion capture system could detect preinjury differences in functional movements between those who did and did not experience a noncontact lower extremity injury (NCLEI). A three-dimensional markerless moti...

Early versus Standard Weight Bearing Following Operative Treatment of Tibial Plateau Fractures: Do We Really Have to Wait So Long?
J Knee Surg DOI: 10.1055/s-0043-1772232Postoperative management of tibial plateau fractures classically involves a prolonged period between 10 and 12 weeks of nonweight bearing or partial weight bearing. In recent years, there has been some support for earlier weight-bearing protocols although this remains controversial. The goal of this study was to investigate the difference in outcomes between early weight-bearing (EWB) and traditional weight-bearing (TWB) protocols. This investigation is a retrospective review of 92 patients treated with open reduction and internal fixation of tibial plateau fractures at a single insti...

Objective Clinical Measurement Tools for Functional Evaluation of the Surgical Patient
J Knee Surg DOI: 10.1055/s-0043-1772222Following knee surgery, clinicians have traditionally used visually rated or time-based assessments of lower extremity movement quality to measure surgical outcomes, plan rehabilitation interventions, and measure success. These methods of assessment are prone to error and do not fully capture a patient's inefficient movement patterns post surgery. Further, currently available systems which objectively measure kinematics during these tasks are expensive and unidimensional. For these reasons, recent research has called for the development of objective and low-cost precision rehabilitati...

Anterior Cruciate Ligament Return to Play: Where Are We Now?
J Knee Surg DOI: 10.1055/a-2130-4909Anterior cruciate ligament reconstruction (ACLR) is a commonly performed orthopaedic procedure, and it is crucial to assess an athlete's readiness to safely return to sports following ACLR to minimize the risk of reinjury. Despite this, determining optimal return to play (RTP) criteria following ACLR that is accurate, accessible, and reproducible remains challenging. This review aims to discuss commonly employed RTP criteria domains, including functional assessments, patient-reported outcomes, and psychological tests, as well as emerging technologies such as magnetic resonance imaging (M...

C. Difficile Infection within 6 Months before TKA Is Associated with Increased Short-Term Complications
Conclusion CDI before TKA was associated with higher odds of postoperative CDI compared with patients without a history of CDI. CDI ≤ 6 months before TKA was associated with the highest odds for postoperative complications and readmissions. Providers should consider delaying TKA after CDI, if possible, to allow for patient recovery and eradication of infection.

More Is Not Merrier: Increasing Numbers of All-Inside Implants Do Not Correlate with Higher Odds of Revision Surgery
J Knee Surg DOI: 10.1055/a-2112-8158The purpose of this study was to evaluate the relationship between the number of all-inside meniscal repair implants placed and the risk of repair failure. We hypothesized that the use of higher numbers of all-inside meniscus repair implants would be associated with increased failure risk. A retrospective chart review identified 351 patients who underwent all-inside meniscus repair between 2006 and 2013 by a sports medicine fellowship–trained orthopaedic surgeon at a single institution. Patient demographics (age, body mass index [BMI], sex) and surgical data (number of implants used, c...
