What is a ruptured patella tendon?
Patella tendon ruptures are extremely painful and may be accompanied with an audible 'pop' at the time of injury. There will be swelling of the knee, particularly at the bottom of the knee over the tendon. The athlete will be unable to put weight on the knee or hold the knee in a straightened position.
What happens?
The patella tendon is prone to rupturing in individuals with a history of patella tendon injury such as jumpers knee or degeneration due to age. Injuries of this type serve to weaken the patella tendon and in the event of strong eccentric quadriceps contraction which is where the muscle contracts while it lengthens such as landing from jump, the patella tendon may snap or rupture most commonly at the lower end of the patella.
What is the treatment?
If the patella tendon becomes completely ruptured across its width and thus surgical intervention is required to repair the damage. This involves suturing (stitching) the torn tendon.
Following surgery the patient will be advised on a specific rehabilitation plan which normally involves little or no weight-bearing on the affected knee and wearing a knee brace to prevent the knee from bending. This may be required for more than 6 weeks.
Once the knee brace has been removed exercises to regain full range of movement and build up the strength of the quadriceps muscle group should be carried out.
Rehabilitation from a patella tendon rupture is extremely slow and it may take between 6 and 12 months before the patient is able to return to sports.
