Background: Microfracture is a single-stage arthroscopic procedure used to treat small- and medium-sized cartilage defects, the clinical results of which have been mixed to date. Purpose: To retrospectively evaluate prospectively collected patient-reported outcomes (PROs) after microfracture as well as to determine patient-related and defect-related factors associated with clinical outcomes and which factors predict the need for additional surgery. Study Design: Case-control study; Level of evidence, 3...

RATIONALE: Considering the risk of osteoarthritis following resection of a horizontally torn meniscus of the knee, repairing and preserving the meniscus as much as possible is preferred. We report 3 cases of restoration of horizontally torn menisci using a novel arthroscopic method we have called "all-inside interleaf vertical suture" that afforded preservation. PATIENT CONCERNS: The 3 patients (aged 14, 17, and 21 years) had knee pain through sports activity. DIAGNOSES: All patients had horizontal tears in the posteromedial part of the meniscus...

The present study investigated the case of a 46-year-old female with primary malignant perivascular epithelioid cell neoplasm (PEComa) of the femur. The patient presented with a 5-month history of right distal thigh pain following trauma. Radiographs of the right distal femur revealed a mixed lytic and sclerotic lesion with subtle areas of cortical destruction and soft tissue extension, consistent with an aggressive tumor. A core biopsy revealed an epithelioid tumor with granular cell features, but a definitive diagnosis could not be made...

Many hip arthroscopy patients experience significant pain in the immediate postoperative period. Although peripheral nerve blocks have demonstrated efficacy in alleviating some of this pain, they come with significant costs. Local infiltration analgesia (LIA) may be a significantly cheaper and efficacious treatment modality. Although LIA has been well studied in hip and knee arthroplasty, its efficacy in hip arthroscopy is unclear. The purpose of this retrospective study is to determine the efficacy of a single extracapsular injection of bupivacaine-epinephrine during hip arthroscopy in reducing the rate of elective postoperative femoral nerve blocks...

BACKGROUND: A multicentre study of single peg Oxford knees reported failure associated with osteoarthritis progression, femoral component loosening, unexplained pain and meniscal bearing dislocation. Suboptimally positioned femoral components and intraoperative MCL damage could explain these problems. We hypothesised that modifying implantation technique to optimise femoral component positioning and MCL preservation, and introducing the twin peg Oxford knee would address these problems and improve longer term survival...

BACKGROUND: Proponents of computer-assisted TKA suggest that better alignment of the TKAs will lead to improved long-term patient functional outcome and survivorship of the implants. However, there is little evidence about whether the improved position and alignment of the knee components obtained using computer navigation improve patient function and the longevity of the TKA. QUESTIONS/PURPOSES: The purpose of this study was to determine whether (1) clinical results; (2) radiographic and CT scan results; and (3) the survival rate of TKA components would be better in patients having computer-assisted TKA than results of patients having TKA without computer-assisted TKA...

RATIONALE: Retrograde femoral nailing was one of the most important treatment means for distal femoral shaft fracture. However, studies regarding heterotopic ossification of the patellar tendon after retrograde intramedullary nailing for distal femoral shaft fracture are limited. We herein present a rare complication, namely heterotopic ossification of the patellar tendon, after retrograde intramedullary nailing for displaced femoral shaft fracture. PATIENT CONCERNS: We present a case of 25-year-old male with displaced femoral shaft fracture who was treated by retrograde intramedullary nailing...

BACKGROUND AND OBJECTIVES: Perineural dexamethasone has been demonstrated to extend postsurgical analgesia after peripheral nerve blockade in adults. The mechanism of action of dexamethasone as a regional anesthetic adjuvant is unclear as intravenous dexamethasone has been shown to have similar analgesic efficacy as perineural dexamethasone. The efficacy of perineural dexamethasone has not been previously explored in the pediatric population. METHODS: After obtaining informed consent, children (aged 10-18 years) presenting for arthroscopic knee surgery with a femoral nerve block were randomized to 1 of 3 groups: ropivacaine 0...

RATIONALE: The fabella is a normal structure, but is occasionally reported to cause posterior knee pain. The aim of this study was to present fabella syndrome after high tibial osteotomy. PATIENT CONCERNS: A 55-year-old female patient was admitted to the hospital due to about 1 year and 8 months of left knee pain. Sclerosis was observed in the anterior margin of the fabella in the preoperative magnetic resonance (MR) T2 image, and reactive bone marrow was found and was considered to be due to degeneration of the distal femur...

BACKGROUND: Cartilage repair algorithms use lesion size to choose surgical techniques when selecting a cartilage repair procedure. The association of fresh osteochondral allograft (OCA) size with graft survivorship and subjective patient outcomes is still unknown. PURPOSE: To determine if lesion size (absolute or relative) affects outcomes after OCA transplantation. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: The study included 156 knees in 143 patients who underwent OCA transplantation from 1998 to 2014 for isolated femoral condyle lesions...

By analyzing a case of total knee arthroplasty (TKA) in a knee with complex deformity and secondary osteoarthritis, we demonstrated the rationale of preoperative planning and the detail of intraoperative execution. The lady had right TKA with combined medial closing wedge femoral osteotomy, neutral wedge valgus derotational tibial osteotomy, fibular osteotomy, and quadriceplasty. Four months later, she had left TKA. Osteotomies healed well and she was pain-free at 18 months after right TKA. Combination of intra-articular and extra-articular correction of deformity was the key to achieve a well-aligned TKA with good soft tissue balancing in both coronal and sagittal planes...

INTRODUCTION: We present the first retrospective study that compares two various autologous matrix-induced chondrogenesis (AMIC) surgical interventions to repair grade III-IV cartilage defects in the knee. Patients who underwent minimally invasive (arthroscopy) or open (mini-arthrotomy) AMIC were followed up to 2 years to investigate if minimally invasive AMIC is superior to open procedures. MATERIALS AND METHODS: Overall n = 50 patients with focal and contained grade III-IV articular cartilage defects in the knee joint were followed in a consecutive cohort study...

PURPOSE: Distal femoral resection in total knee arthroplasty (TKA) is commonly performed using intramedullary jigs with a pre-operatively planned valgus cut angle (VCA). For valgus knees with lateral femoral condyle hypoplasia, the method of determining the accurate VCA has not been clarified. The aim of the present study is to introduce a method that can accurately determine the distal femoral VCA in the valgus knee arthroplasty. METHODS: Twenty patients with valgus deformity caused by lateral femoral condylar hypoplasia underwent primary TKA with individually measured VCA...

Surgical strategies for knee joint preservation are numerous, with the procedure(s) of choice for a given patient dependent on the status of the articular cartilage, meniscus, overall alignment, and ligamentous stability. For patients with large, isolated, osteochondral defects of the articular cartilage of the femoral condyle, osteochondral allograft transplantation (OCA) is often performed in an effort to reduce pain and improve function. Similarly, for appropriately indicated patients with symptomatic meniscus deficiency, meniscus allograft transplantation (MAT) is an excellent surgical solution...

BACKGROUND AND OBJECTIVES: High-dose intravenous dexamethasone reduces the postoperative opioid requirement and is often included in the multimodal analgesia strategy after total knee arthroplasty (TKA). Combined obturator nerve and femoral triangle blockade (OFB) reduces the opioid consumption and pain after TKA better than local infiltration analgesia (LIA). The question is whether preoperative high-dose intravenous dexamethasone would cancel out the superior analgesic effect of OFB compared with LIA...

BACKGROUND: Osteochondral autologous transplantation surgery (OATS) has been advocated for unstable osetochondritis dissecans (OCD) lesions of the adolescent capitellum, though limited information is available regarding clinical and radiographic results in North American patients. We hypothesize that single-plug OATS is safe and effective in alleviating pain and restoring function in unstable OCD. METHODS: Twenty-eight patients with unstable OCD treated with single-plug OATS were evaluated...
