Summary: Limb lengthening after TKA is common, and it is significantly more in valgus than varus deformity. Significant LLD (>= 10 mm) is associated with suboptimal functional outcome.

Summary: This study investigated the relationship between measured and perceived limb length discrepancy (LLD) in total hip arthroplasty (THA) patients. It found a correlation between increasing postoperative limb length change and perceived LLD, with 63% of patients experiencing improvement or full resolution of symptoms during the follow-up period. Further research is needed to identify risk factors for persistent LLD.

Summary: Large changes in leg length are common after hinge TKA, likely secondary to altered soft tissue constraints. Surgeons should be aware of potential changes in leg length and incorporate this into preoperative planning and patient counseling.

Summary: Metaphyseal cones and sleeves offer equally durable survivorship in revision TKA, with periprosthetic joint infection being the most common mode of implant failure.

Summary: In a cohort of 100 patients, it was found that approximately 1 in 6 patients had a limb length discrepancy of >10 mm when measured from different knee joint reference points. Female gender was significantly associated with increased femoral length asymmetry.

Summary: This study investigated the inter-limb differences in mechanical work in LLD and the relationship between LLD magnitude and mechanical work performed by each lower limb. The results showed significant inter-limb difference of mechanical work in LLD and negative correlations with positive and negative ILM work performed by the shorter limb. Differences in adaptation strategies were found between different severity levels of LLD.

Summary: This meta-analysis aimed to evaluate whether intraoperative fluoroscopy improves component positioning compared to no fluoroscopy during direct anterior total hip arthroplasty. The results showed no significant differences in cup inclination angle, cup anteversion angle, or limb-length discrepancy between the groups. Further studies are needed to determine the clinical benefits of intraoperative fluoroscopy in direct anterior total hip arthroplasty.

Summary: This study compared the survivorship and aseptic revision rates of metaphyseal cones and sleeves at intermediate follow-up. The results showed that there were no significant differences in survivorship over a one-year, two-year, and five-year follow-up when comparing tibial and femoral sleeves to cones directly. Both sleeves and cones performed well at an intermediate-term follow-up.

Summary: This study evaluates the cost-effectiveness of tibial cones in revision total knee arthroplasty and finds that they may be cost-effective at lower prices, in younger patients, or in high-risk patients.

Summary: The utilization of cementless metaphyseal fixation in revision total knee arthroplasty has increased over time, with tibial metaphyseal cones being the most commonly used implants.

Summary: This study examines the mid-term functional and radiographic outcomes in patients undergoing complex revision total knee arthroplasty with a novel metaphyseal cone system. The results show that excellent results can be achieved regardless of the stem fixation technique used.

Summary: The study compared the reliability of a novel 3D method with the standard 2D technique for lower limb discrepancy measurement, showing higher intra- and inter-observer reliability with the 3D method.

Summary: Concurrent total knee arthroplasty and revision internal fixation is effective in achieving union in patients with distal metaphyseal femur nonunion and loss of fixation in the setting of coronal-plane deformity induced by knee arthritis. Short-term total knee arthroplasty survival rate is high, with significant improvement in patient mobility.

Summary: The study evaluated the survivorship and radiographic outcomes of using metaphyseal cones with short cemented stems in revision total knee arthroplasty. The results showed excellent outcomes without the need for long-stem fixation, avoiding potential complications.

Summary: This study conducted a systematic review on the treatment methods for knee osteoarthritis. It found that total knee arthroplasty (TKA) and unicompartmental knee arthroplasty (UKA) are better options for treating osteoarthritis, while knee joint distraction (KJD) is an imperfect option.
