We describe the diagnosis, treatment, rehabilitation, and complications of a 27-year-old male paraskiier who sustained a closed high-velocity knee dislocation after colliding with a tree at a speed of 45 mph and falling 40 feet to the ground. Extensive surgery to repair and reconstruct the knee included open lateral capsular repair, open anatomical posterolateral corner reconstruction with split Achilles tendon allograft, open iliotibial band reconstruction with Achilles tendon allograft, arthroscopic anterior cruciate ligament reconstruction with bone-patellar tendon-bone autograft, and double-bundle posterior cruciate ligament reconstruction with Achilles tendon allograft for the anterolateral bundle and tibialis anterior tendon allograft for the posteromedial bundle...

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...

Brian J Eckenrode
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...

BACKGROUND: Early clinical results of anterolateral ligament (ALL) reconstruction are promising, but concerns exist due to high rates of complications after other types of lateral extra-articular tenodesis. The rate of surgery after combined anterior cruciate ligament (ACL) and ALL reconstruction is not known. PURPOSE: To determine the rate of reoperation after combined ACL and ALL reconstruction. STUDY DESIGN: Case series; Level of evidence, 4...

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...

PURPOSE: Magnetic resonance imaging (MRI) and single-photon emission computerised tomography/computerised tomography (SPECT/CT) are used as diagnostic tools in symptomatic patients after reconstruction of the anterior cruciate ligament (ACL). The benefit of SPECT/CT in comparison with MRI is under debate. The purpose of this study was to investigate whether and how bone tracer uptake (BTU) intensity and distribution in SPECT/CT correlate with MRI findings in symptomatic patients after ACL reconstruction...

REVIEW
Hee-Nee Pang, Hamid Rahmatullah Bin Abd Razak, Stephen Petis, Douglas D R Naudie, Steven J MacDonald
The use of modular total knee arthroplasty (TKA) implants allows surgeons to perform isolated tibial polyethylene insert exchange (IPE) while retaining well-fixed and stable components.The purported advantages of IPE include preservation of bone stock, shorter operating time, less blood loss, faster rehabilitation and lower cost. However, the indications for IPE are limited.IPE for wear and osteolysis has moderate success in the medium term but should be avoided in cases of accelerated wear. In selected cases, debridement and IPE for early infection can result in low morbidity with high success rates in the short term...

James C Chow, Leigh Breslauer
Albeit multifactorial, patient satisfaction is predominantly driven by postoperative pain and function. Unfortunately, approximately 20% of total knee arthroplasty (TKA) recipients are dissatisfied with the outcome of their surgery. Objective balancing of the soft tissue envelope may contribute to significant decrease in pain and increase in function when compared with traditional subjective methods. In an effort to confirm this, a cohort of manual TKA patient outcomes was compared with sensor-assisted TKA outcomes...

#18
Markus Preis, Travis Bailey, Lucas S Marchand, Alexej Barg
BACKGROUND: In patients with painful ankle arthrodesis, the surgical treatment is challenging, and may include takedown of ankle arthrodesis and conversion to a total ankle replacement (TAR). This procedure is technically demanding given the altered anatomy after arthrodesis. Few studies have evaluated TAR in the setting of prior arthrodesis. QUESTIONS/PURPOSES: (1) What intraoperative and perioperative complications were observed in patients who underwent conversion of an ankle arthrodesis to a TAR? (2) Was durable fixation achieved at short term, and what was the alignment of the components? (3) What subsequent surgical procedures were performed, including revisions? (4) What improvements were observed in pain, tibiotalar range of motion (ROM), and quality of life? METHODS: Between January 2007 and December 2014, 18 patients with a painful ankle arthrodesis underwent conversion to TAR at our tertiary referral center...

REVIEW
Hai V Le, Stella J Lee, Ara Nazarian, Edward K Rodriguez
Adhesive shoulder capsulitis, or arthrofibrosis, describes a pathological process in which the body forms excessive scar tissue or adhesions across the glenohumeral joint, leading to pain, stiffness and dysfunction. It is a debilitating condition that can occur spontaneously (primary or idiopathic adhesive capsulitis) or following shoulder surgery or trauma (secondary adhesive capsulitis). Here, we review the pathophysiology of adhesive shoulder capsulitis, highlighting its clinical presentation, natural history, risk factors, pathoanatomy and pathogenesis...

OBJECTIVES: Sustained intra-articular delivery of pharmacological agents is an attractive modality but requires use of a safe carrier that would not induce cartilage damage or fibrosis. Collagen scaffolds are widely available and could be used intra-articularly, but no investigation has looked at the safety of collagen scaffolds within synovial joints. The aim of this study was to determine the safety of collagen scaffold implantation in a validated in vivo animal model of knee arthrofibrosis...
