BACKGROUND: Despite the enactment of laws to restrict the practice of self-referral, exceptions in these prohibitions have enabled these arrangements to persist and proliferate. Most research documenting the effects of self-referral arrangements analyzed claims records from Medicare beneficiaries. Empirical evidence documenting the effects of self-referral on use of services and spending incurred by persons with private insurance is sparse. OBJECTIVES: We analyzed health insurance claims records from a large private insurer in Texas to evaluate the effects of physician self-referral arrangements involving physical therapy on the treatment of patients with frozen shoulder syndrome, elbow tendinopathy or tendinitis, and patellofemoral pain syndrome...

BACKGROUND: Limited quantitative, physiological evidence exists regarding the effectiveness of Kinesio® Taping methods, particularly with respect to the potential ability to impact underlying physiological joint space and structures. To better understand the impact of these techniques, the underlying physiological processes must be investigated in addition to the examination of more subjective measures related to pain in unhealthy tissues. HYPOTHESIS/PURPOSE: The purpose of this study was to determine whether the Kinesio® Taping Space Correction Method created a significant difference in patellofemoral joint space, as quantified by diagnostic ultrasound...

BACKGROUND: Quadriceps strengthening exercises are part of the treatment of patellofemoral pain (PFP), but the heavy resistance exercises may aggravate knee pain. Blood flow restriction (BFR) training may provide a low-load quadriceps strengthening method to treat PFP. METHODS: Seventy-nine participants were randomly allocated to a standardised quadriceps strengthening (standard) or low-load BFR. Both groups performed 8 weeks of leg press and leg extension, the standard group at 70% of 1 repetition maximum (1RM) and the BFR group at 30% of 1RM...

BACKGROUND: The source of pain in patellofemoral osteoarthritis is not fully understood. The purpose of this study was to identify the origin of pain using intraosseous pain catheters and to show early results with an osteotomy that is potentially denervating and hydrostatic pressure-relieving. METHODS: Five patients with patellofemoral osteoarthritis and pain with straight downward patellofemoral compression were included. All underwent arthroscopic placement of two 0...

PURPOSE: Anterior knee pain after total knee arthroplasty (TKA) remains a widely discussed postoperative complication. In contrast to sports traumatology, the role of the dissected medial patellofemoral ligament (MPFL) using a medial parapatellar approach in TKA has not been discussed so far. In the present study, it was hypothesized that the attempted repair of the MPFL in TKA by simple closure of the joint capsule may not be successful in some cases, causing anterior knee pain. Furthermore, it was hypothesized, that the success of repair might be influenced by femoral component rotation...

BACKGROUND: Patellofemoral pain (PFP) is considered one of the commonest forms of knee pain. This study aimed to identify how physiotherapists in the United Kingdom (UK) currently manage patellofemoral pain (PFP), particularly in relation to exercise prescription, and response to pain. METHODS: An anonymous survey was designed with reference to previous surveys and recent systematic reviews. Practising UK physiotherapists who treat patients with PFP were invited to take part via an invitation email sent through professional networks, the 'interactive Chartered Society of Physiotherapy (iCSP)' message board, and social media (Twitter)...

Objective Subjective crepitus is the complaint of hearing grating, cracking or popping sounds in and/or around a joint. We aimed to evaluate whether there is an association between crepitus and incident symptomatic knee osteoarthritis (SOA) in the Osteoarthritis Initiative (OAI), a multicenter longitudinal U.S. cohort. Methods Knees without baseline SOA were included. Crepitus frequency was assessed using a question from the Knee Injury and Osteoarthritis Outcome Score (KOOS) at baseline, 12-, 24-, and 36-month visits...

BACKGROUND: Physical activity levels seem to play a role in patellofemoral pain (PFP); however, few studies have been conducted to confirm this hypothesis. OBJECTIVES: To determine the reported pain levels of women with and without PFP who maintain different levels of physical activity; to determine the capability of these levels to predict pain; and to test the capability of two stair-negotiation protocols, with and without external load, to equalize pain between groups...

Patellar instability resulting from subluxation or dislocation is a painful and commonly recurring condition. Retinacular restraints control patellar tracking, limiting the movement of the patella in the trochlear groove. The medial patellofemoral ligament (MPFL) is considered the main soft tissue stabilizer against lateral displacement. Few studies of patellar instability discuss rehabilitation after MPFL reconstruction. In this review, we discuss the phases of rehabilitation after MPFL reconstruction, typical interventions by rehabilitation specialists, and patient-specific guidelines for return to prior level of function...

AIMS: It is not clear whether anterior knee pain and osteoarthritis (OA) of the patellofemoral joint (PFJ) are contraindications to medial unicompartmental knee arthroplasty (UKA). Our aim was to investigate the long-term outcome of a consecutive series of patients, some of whom had anterior knee pain and PFJ OA managed with UKA. PATIENTS AND METHODS: We assessed the ten-year functional outcomes and 15-year implant survival of 805 knees (677 patients) following medial mobile-bearing UKA...

BACKGROUND: Patellofemoral joint osteoarthritis is a common condition, yet information regarding conservative management is lacking. Foot orthoses are an effective intervention for improving pain and function in younger individuals with patellofemoral pain and may be effective in those with patellofemoral osteoarthritis. This pilot study will seek to establish the feasibility of a phase III randomised controlled trial to investigate whether foot orthoses worn in prescribed motion controlled footwear are superior to prescribed motion control footwear alone in the management of patellofemoral osteoarthritis...

BACKGROUND: Anterior knee pain has been reported as a major postoperative complication after total knee arthroplasty, which may lead to patient dissatisfaction. Rotational alignment and the medial-lateral position correlate with patellar maltracking, which can cause knee pain postoperatively. However, the superior-inferior position of the patellar component has not been investigated. The purpose of the current study was to investigate the effects of the patellar superior-inferior position on patellofemoral kinematics and kinetics...

There is no shortcut to accurate diagnosis in the patellofemoral pain patient. Most important in the process is a desire and ability to specifically identify the structural and biomechanical origin of pain. This can be elusive and often requires a careful analysis of all factors affecting the patient, including documenting his or her specific history of pain origin and specific treatments to date, and acknowledging the patient's localization of the pain origin. Many patients can pinpoint the site of pain origin when given the time and encouragement to do so...
