Complications involving the extensor mechanism after TKA are potentially disastrous. We are reporting a case of patellar tendon rupture from tibial tuberosity following total knee arthroplasty. We managed it by direct repair with fiberwire using Krackow suture technique without augmentation. Our long term result has been very encouraging. Our method is a safe and better method of management of ...

The present study investigated the mechanical properties of tendon fascicles from the anterior and posterior human patellar tendon. Collagen fascicles from the anterior and posterior human patellar tendon in healthy young men (mean +/- SD, 29.0 +/- 4.6 yr, n = 6) were tested in a mechanical rig. A stereoscopic microscope equipped with a digital camera recorded elongation. The fascicles were pre...

Objective: The goal of this study was to compare the results of knee anterior cruciate ligament reconstruction with the use of patellar tendon and quadriceps tendon. Methodology: In this study 30 patients with rupture of anterior cruciate ligament of knee were compared in two 15-person group with the use of patellar tendon and quadriceps tendon. After precise rehabilitation program for six mont...

Disorders of the deep infrapatellar bursa are important to include in the differential diagnosis of anterior knee pain. Knowledge regarding its anatomic location can aid the clinician in establishing a proper diagnosis. Fifty cadaveric knees were dissected, and the deep infrapatellar bursa had a consistent anatomic location in all specimens. The deep infrapatellar bursa was located directly pos...

Adolescence may be regarded as a critical phase of tissue plasticity in young growing athletes, as the adaptation process of muscle-tendon unit is affected by both environmental mechanical stimuli and maturation. The present study investigated potential imbalances of knee extensor muscle strength and patellar tendon properties in adolescent compared with middle-aged athletes featuring long-term...

Cryopreserved patellar tendon allografts are often recommended for reconstruction of anterior cruciate ligaments (ACLs) because living donor fibroblasts are thought to promote repair. Animal studies, however, indicate that ligaments regenerate from recipient rather than donor cells. If applicable to man, these observations suggest that allograft cell viability is unimportant. We therefore used ...

PURPOSE To evaluate the stages of patellar tendon graft remodelling using magnetic resonance imaging (MRI) after anterior cruciate ligament (ACL) reconstruction with or without platelet-rich plasma (PRP) injection. METHODS 98 patients aged 18 to 65 years with complete rupture of the ACL were randomised to undergo reconstruction with the autologous patellar tendon grafts with or without PRP in...

OBJECTIVE To evaluate the prevalence and type of dysesthesia around the incision used to obtain the patellar tendon for anterior cruciate ligament (ACL) reconstruction surgery. METHODS Out of a population of 1368 ACL reconstructions using the central third of the patellar tendon, 102 patients (111 knees) were evaluated by means of telephone interview. RESULTS The mean follow-up was 52 month...

The moment arm (MA) of the knee extensor mechanism has been reported by a number of researchers, although it has been defined and measured differently in these studies. The aims of this study were: (1) to quantify the MA of the knee-extensor mechanism, which is represented by the MA of the patellar tendon at the knee; and (2) to show that the MA of the patellar tendon is related to the size of ...

Patellar tendon rupture is an uncommon clinical presentation, which generally affects the under 40s who are active in sport. Bilateral rupture of both tendons is much rarer. It occurs most frequently in patients with predisposing factors such as corticosteroid use or systemic diseases. The authors present the case of a 56-year-old male on long-term statin therapy who sustained this injury follo...
