AIM: To evaluate the influence of the titanium nitride (TiN) coating on the results of a total knee arthroplasty (TKA). METHODS: A total of 910 patients (338 men; 572 woman), with a mean age of 65 (range 36-94) undergoing 1031 primary TKAs were assessed. Clinical evaluation and patient-reported outcomes were gathered one year after surgery. The questionnaires included the Knee injury and Osteoarthritis Outcome Score (KOOS)-Dutch version, Visual Analogue Scale (VAS) pain scores in rest and during active knee movement, VAS-satisfaction scores, and EQ-5D-3L health scores...

BACKGROUND: Arthrofibrosis in the suprapatellar pouch and anterior interval can develop after knee injury or surgery, resulting in anterior knee pain. These adhesions have not been biomechanically characterized. METHODS: The biomechanical effects of adhesions in the suprapatellar pouch and anterior interval during simulated quadriceps muscle contraction from 0 to 90° of knee flexion were assessed. Adhesions of the suprapatellar pouch and anterior interval were hypothesized to alter the patellofemoral contact biomechanics and increase the patellofemoral contact force compared to no adhesions...

CASE: We describe a case of refractory Lyme arthritis in an adolescent patient with a concomitant medial meniscal tear. The patient underwent arthroscopic synovectomy and meniscal repair, and required additional surgery for subsequent decreased range of motion. We describe the presentation, the intraoperative findings, the course of recovery, and the literature regarding Lyme arthritis and meniscal tears. CONCLUSION: Refractory Lyme arthritis commonly is treated successfully with arthroscopic synovectomy...

The cyclops lesion is a localized anterior arthrofibrosis most commonly seen following anterior cruciate ligament reconstruction. The lesion forms at the anterior cruciate ligament insertion creating a painful extension block between femoral intercondylar notch and tibial plateau. We present 2 cases (3 knees) in which cyclops lesions appeared atypically following bicruciate-retaining total knee replacement. Two lesions occurred in a single patient following bilateral knee replacement. One lesion occurred in an active sportswoman...

PURPOSE: To compare acute ACL reconstruction (ACLR) within 8 days of injury with delayed reconstruction after normalized range of motion (ROM), 6-10 weeks after injury. It was hypothesized that acute ACL reconstruction with modern techniques is safe and can be beneficial in terms of patient-reported outcomes and range of motion. METHODS: Sample size calculation indicated 64 patients would be required to find a 5° difference in ROM at 3 months. Seventy patients with high recreational activity level, Tegner level 6 or more, were randomized to acute (within 8 days) or delayed (6-10 weeks) ACLR between 2006 and 2013...

BACKGROUND: The use of autologous osteochondral grafts has become popular in the treatment of small, isolated, well-contained articular cartilage defects. However, donor site morbidity is a problem, and few reports are available of donor site morbidity after mosaicplasty. PURPOSE: To examine the clinical outcomes of donor sites after osteochondral grafts from healthy knees. STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Between September 1997 and September 2011, there were 40 patients (40 knees; 32 men, 8 women; 31 right knees, 9 left knees) with asymptomatic osteochondral graft donor sites used for autologous transfer; all had a follow-up period of >2 years...

BACKGROUND: Until recently, anterior cruciate ligament (ACL) tears in older patients were treated conservatively; however, these patients often experienced significant pain and instability. PURPOSE/HYPOTHESIS: The purpose of this study was to compare the patient-reported outcomes, patient satisfaction, and failure rates of primary ACL reconstruction between a younger (age 20-30 years) and older (age 50-75 years) patient cohort. It was hypothesized that patients in the older cohort could achieve comparable clinical outcomes and retear rates following ACL reconstruction with a bone-tendon-bone autograft or allograft compared with the younger patients...

BACKGROUND: Tibial spine fractures are rare, complex injuries. Management remains varied given a lack of consensus about the optimal approach. Thus, the purpose of this study is to determine prevailing strategies among pediatric orthopaedists and establish areas of agreement and ongoing controversy in the management of tibial spine fractures. METHODS: An electronic survey was distributed to the Pediatric Orthopaedic Society of North America (POSNA) membership. Surgeon demographics, experience, and responses to clinical vignettes were collected...

PURPOSE: Most of the clinical outcome studies dealing with ACL repair are from the developer's perspective. It is a fact that these developer-initiated studies tend to interpret the results rather in favour than against their developed technique or product. Hence, it was the purpose of the present independent investigator-initiated study to investigate the clinical and radiological outcomes as well as failure rate of patients who underwent an ACL suture using dynamic intraligamentary stabilisation device in a specialised independent knee clinic...

BACKGROUND AND PURPOSE: Loss of knee range of motion (ROM) has been reported as the most common complication following anterior cruciate ligament reconstruction (ACLR). Arthrofibrosis of the knee, or specifically Cyclops syndrome, has been described as the formation of a scar tissue nodule adjacent to the tibial tunnel of the anterior cruciate ligament (ACL) graft. This lesion often results in loss of knee extension ROM, pain, and impaired function. CASE DESCRIPTIONS: Three consecutive patients were referred to physical therapy following arthroscopic knee surgery for lysis of adhesions of a Cyclops lesion from a previous ACLR...

STUDY DESIGN: Case report. BACKGROUND: Arthrofibrosis is a debilitating condition that results in pain, decreased range of motion, and decreased function. Although surgical management of arthrofibrosis has been well described in the literature, rehabilitation of the arthrofibrotic knee is less well described. CASE DESCRIPTION: A 28-year-old female presented with swelling, pain, and decreased strength, range of motion, patellar mobility, and function following an exploratory arthroscopy of her left knee...

BACKGROUND: Dwarfism is associated with skeletal dysplasias and joint deformities that frequently result in osteoarthritis requiring treatment with total knee arthroplasty (TKA). These surgeries can be challenging because of alignment deformities, poor bone stock, and smaller components. This study aims to compare TKA implant survivorship and complications between dwarf and nondwarf patients. METHODS: A retrospective case-control study was performed from 1997-2014 evaluating 115 TKAs in patients under the height threshold of 147...

Substance P (SP), a neurotransmitter released after injury, has been linked to deregulated tissue repair and fibrosis in musculoskeletal tissues and other organs. Although SP inhibition is an effective treatment for nausea, it has not been previously considered as an anti-fibrotic therapy. Although there are extensive medical records of individuals who have used SP antagonists, our analysis of human registry data revealed that patients receiving these antagonists and arthroplasty are exceedingly rare, thus precluding a clinical evaluation of their potential effects in the context of arthrofibrosis...

Arthrofibrosis of the talocalcaneonavicular joint can follow talar neck fracture especially if anterior approaches have been used for fracture fixation. Capsular release of the talocalcaneonavicular joint is indicated if the painful hindfoot stiffness cannot be controlled with conservative treatment. Open capsular release of the talocalcaneonavicular joint demands extensive soft tissue dissection and hinders early postoperative mobilization exercise of the joint. The purpose of this technical note is to describe a minimally invasive approach of arthroscopic capsular release of the talocalcaneonavicular joint that is composed of arthroscopic release of the talonavicular joint and the anterior subtalar joint...

BACKGROUND: While revision anterior cruciate ligament reconstruction (ACLR) can be performed to restore knee stability and improve patient activity levels, outcomes after this surgery are reported to be inferior to those after primary ACLR. Further reoperations after revision ACLR can have an even more profound effect on patient satisfaction and outcomes. However, there is a current lack of information regarding the rate and risk factors for subsequent surgery after revision ACLR. PURPOSE: To report the rate of reoperations, procedures performed, and risk factors for a reoperation 2 years after revision ACLR...
