Expanded adipose derived mesenchymal stromal cells are effective in treating chronic insertional patellar tendinopathy: clinical and MRI evaluations of a pilot study.

Purpose: Effect of ultrasound guided injections of autologous ASCs in chronic recalcitrant patellar tendinopathy.

Methods: Fourteen patients (16 knees, 12/2 males/females) with chronic, recalcitrant (unsuccessfully treated with nonoperative treatments) insertional PT underwent clinical evaluation and magnetic resonance imaging (MRI) before intervention. Stromal vascular fraction cells (SVF) were expanded by in-vitro culture and characterized by flow cytometry.

Image-guided intervention in the management of chronic patellar tendinopathy with calcification: a three-pronged approach.

Patellar tendinopathy is a common cause of knee pain and functional impairment in athletes. It is commonly managed using conservative measures such as physiotherapy, but cases that are refractory to such treatment may require a more invasive approach. Various forms of image-guided injection therapy have been described in the literature.

The association of patellar tendinosis with patellar maltracking and Hoffa's fat pad impingement: A case-control MRI study.

Objectives: To assess whether proximal or distal patellar tendinosis is associated with patellar maltracking parameters and superolateral Hoffa's fat pad impingement.

Methods: Institutional radiology database was reviewed for knee MRI scans performed over a 7-year period identifying cases of unequivocal patellar tendinosis, which were separated into 2 groups: proximal and distal tendinosis. For each group of proximal and distal patellar tendinosis, a control group of age and gender matched subjects was assigned.

Relationship of Patellofemoral Angles and Tibiofemoral Rotational Angles With Jumper's Knee in Professional Dancers: An MRI Analysis.

Background: Jumper's knee is a type of tendinopathy affecting the distal insertion of the quadriceps tendon (25% of cases) or the patellar tendon. It has been shown that frontal-plane measurements, such as genu valgum, genu varum, an increased quadriceps angle, a protuberant tibial tuberosity, patella alta, and short hamstring muscles, may be related to jumper's knee.

Purpose: To investigate the effects of tibiofemoral rotational angles and patellofemoral (PF) angles on the development of jumper's knee in professional folk dancers.

Pain-guided activity modification during treatment for patellar tendinopathy: a feasibility and pilot randomized clinical trial.

Background: Activity modification is a key component of patellar tendinopathy treatment but there is a lack of evidence guiding activity modification prescription. Use of activity modification in treatment studies has varied widely and the impact of those recommendations has not been directly investigated or compared. The purpose of this study was to assess (1) the feasibility of using pain-guided activity modification during treatment for patellar tendinopathy and (2) if our outcome measures are responsive to changes in tendon health over the course of treatment.

The Jumper's Knee - a New Look at Non-surgical Treatment. Pilot Study.

Background: There are many opinions and views regarding the methods of treatment of patellar ligament enthesopathy. No gold standard of treatment exists. This paper presents our approach involving conservative treatment and an appropriate rehabilitation regime.

IN-SEASON REHABILITATION PROGRAM USING BLOOD FLOW RESTRICTION THERAPY FOR TWO DECATHLETES WITH PATELLAR TENDINOPATHY: A CASE REPORT.

Background And Purpose: Patellar tendinopathy is an overuse injury experienced primarily by athletes; especially athletes who participate in sports that involve frequent jumping. Therapeutic exercise is the primary conservative treatment for patients with this condition. However, some patients with patellar tendinopathy may be unable to tolerate the loading that occurs during exercise.

Non-extension movements inducing over half the mechanical energy directly contributing to jumping height in human running single-leg jump.

The running single-leg jump (RSLJ), including certain non-extension movements (movements not induced by lower-limb extension works), is the highest jumping mode in humans. Here, we show the substantial contributions of non-extension movements, in generating mechanical energy directly contributing to the jumping height (E) in RSLJ. We determined the component of increase in E due to each segment movement in RSLJs by 13 male high-jumpers.

Physical Therapist Management of Anterior Knee Pain.

Purpose Of Review: Anterior knee pain is a common musculoskeletal complaint among people of all ages and activity levels. Non-operative approaches with an emphasis on physical therapy management are the recommended initial course of care. The purpose of this review is to describe the current evidence for physical therapist management of anterior knee pain with consideration of biomechanical and psychosocial factors.

Biomechanical agreement between different imitation jumps and hill jumps in ski jumping.

Even though the take-off in ski jumping is decisive, athletes only have a very limited number of training trials on the actual ski jump to practice under real ski jump conditions. Hence, various imitation jumps aiming to mimic the hill jump are performed during daily training. These imitation jumps should therefore mimic the kinematic pattern of hill jumps appropriately.

[Transarterial Periarticular Embolization (TAPE): Indications and Initial Experience in Germany].

Purpose:  The purpose of this article is to demonstrate the potential indications, procedural technique and initial results of the transarterial periarticular embolization (TAPE).

Material And Methods:  TAPE was performed in three patients with chronic pain in different joints. In the first case the patient suffered from osteoarthritis of the shoulder, in the second case from epicondylitis humeri ulnaris ("golfer-elbow") and in the third case from patellar tendinitis ("jumpers-knee").

Self-reported jumpers' knee is common in elite basketball athletes - But is it all patellar tendinopathy?

Objectives: To describe the prevalence and pain location of self-reported patellar tendinopathy and patellar tendon abnormality in a male elite basketball population.

Design: Cross-sectional.

Setting: Pre-season tournament.

Rethinking Patellar Tendinopathy and Partial Patellar Tendon Tears: A Novel Classification System.

Background: Patellar tendinopathy is an overuse injury of the patellar tendon frequently affecting athletes involved in jumping sports. The tendinopathy may progress to partial patellar tendon tears (PPTTs). Current classifications of patellar tendinopathy are based on symptoms and do not provide satisfactory evidence-based treatment guidelines.

Surgical Technique for Chronic Proximal Patellar Tendinopathy (Jumper's Knee).

Chronic proximal patellar tendinopathy is a challenging condition for its troublesome management in the active patient and difficulty in defining the failure of conservative treatment to indicate surgery. Usually, patients with chronic proximal patellar tendinopathy have already tried several physiotherapeutic modalities and are away from their preferred physical activities for variable periods. The current literature presents some open and even arthroscopic options for treating recalcitrant patellar tendinopathy using a variable magnitude of resources and costs.

Don't forget the jumper's knee in the young sportsman: evaluation of patellar tendinopathy with a high frequency ultrasound probe.

Patellar tendinopathy, or Jumper's knee, is a painful knee condition caused by inflammation of the patella tendon. This condition is most frequently observed in subjects who play sports that require repetitive regular jumping. Jumper's knee is frequently misdiagnosed as a minor injury and many athletes, like our patient, keep on training and competing and either tend to ignore the injury or attempt to treat it themselves.

Surgery for patellar tendinopathy (jumper's knee).

Background: Patellar tendinopathy is an overuse condition that commonly affects athletes. Surgery is usually offered if medical and physical therapies fail to treat it effectively. There is variation in the type of surgery performed for the condition.

Injection therapies for patellar tendinopathy.

Patellar tendinopathy, or jumper's knee is a common musculoskeletal condition characterized by progressive activity-related pain on the anterior aspect of the knee and tenderness on the patellar tendon. A conservative method is often the first choice of treatment, which can include anti-inflammatory medication, injection therapies, physiotherapy, eccentric exercises, extra corporeal shock wave therapy, orthosis, etc. Although there are several treatment options available, the management of patellar tendinopathy is still controversial.

Distinguishing Quadriceps Tendinopathy and Patellar Tendinopathy: Semantics or Significant?

Jumper's knee is not synonymous with patellar tendinopathy. The term includes patellar tendinopathy and quadriceps tendinopathy. Although the patellar and quadriceps tendons work in tandem as part of the extensor mechanism of the knee, they have distinct anatomy and functional roles.

Pattern analysis of a complete Achilles tendon rupture suffered during high jump preparation in an official national-level athletic competition.

Elite athletes are subject to injuries like the Achilles tendon rupture. This injury requires a long recovery process, with no guarantee of returning to the pre-injury level. When a rupture happens during natural life, movement analysis can provide useful insights concerning patterns of rupture to understand and prevent Achilles tendon injuries.
