Patella Tendon Repair
A patella tendon repair is a surgical procedure performed to repair or reconstruct the patella tendon after it has been ruptured. The patella tendon connects the kneecap (patella) to the shin bone (tibia) and plays a critical role in straightening the knee and enabling movements such as walking, running, and jumping. A rupture of the patella tendon severely affects knee function, making surgical repair essential to restore normal knee movement and strength.
The patella tendon is the continuation of the quadriceps tendon, running centrally over the front of the kneecap (patella) and attaching the quadriceps (thigh muscle) to the top of the tibia (shin bone). This tendon is a very thick and strong band that primarily assists in straightening the leg, transmitting the force generated by the contracting quadriceps. Due to its critical role in leg extension and weight-bearing activities, the patella tendon endures a significant amount of force during everyday movements and athletic activities.
Injury to the patella tendon can result in either a partial tear or a complete rupture. Both types of injury commonly occur when a violent force is exerted by the contracting quadriceps muscle—for example, when landing from a jump. A rupture of the patella tendon can lead to a significant loss of knee function and may make it impossible to straighten the leg, severely affecting mobility and daily activities.
A patella tendon injury can sometimes be managed non-surgically, but this is generally only appropriate for a partial tear where the patient can still actively use their knee. In such cases, conservative treatment involves immobilisation of the knee and a structured physiotherapy programme to restore strength and function once the tendon has sufficiently healed. However, if the patella tendon is completely ruptured, surgical repair is essential to restore knee function and enable the patient to regain the ability to straighten the leg.
Surgical repair of a ruptured patella tendon is ideally performed as soon as possible after the injury, though in some cases it can be delayed up to a week to allow swelling to subside and reduce the risk of complications. During the procedure, the surgeon first trims any damaged or frayed edges of the tendon. The torn tendon edges are then either sutured (stitched) back together or reattached to the bone using tunnels drilled into the patella (kneecap) or tibia (shin bone). In cases of severe rupture, the surgeon may opt to reconstruct the patella tendon using a graft. This graft can either come from the patient’s own tissue (autograft) or from a donor (allograft). Common autograft options include a portion of the hamstring tendon or Achilles tendon, which are used to replace or reinforce the damaged patella tendon.
After a ruptured patella tendon, surgical repair is essential to restore knee function, reduce pain, and improve stability. Repairing the tendon also helps prevent future complications, such as decreased mobility or the development of degenerative changes like arthritis in the knee joint.
Physiotherapy before patella tendon repair
After a patella tendon rupture, surgical repair is usually performed immediately. However, in some cases, surgery may be delayed for 4 to 7 days to ensure the tendon is in optimal condition for repair. During this time, your injured knee will be immobilised to prevent further damage. Physiotherapy prior to patella tendon surgery focuses on strengthening other joints in your injured leg, such as your hip and ankle, and maintaining strength and movement in your uninjured leg. This pre-surgery preparation helps provide maximum support for your knee after the tendon repair and contributes to a more successful recovery.
Symptoms after patella tendon repair
After your patella tendon repair, it is normal to experience pain, swelling, stiffness, and a limited range of movement in your knee. Your knee will be immobilised with a knee brace to protect the repaired tendon, and you will be provided with elbow crutches to allow partial weight bearing as tolerated. Driving will not be advised for up to 6 weeks following your surgery to ensure safe healing and protect the repair.
Physiotherapy after patella tendon repair
Physiotherapy after a patella tendon repair is essential to ensure the success of your surgery. A comprehensive physiotherapy programme with acephysiosports.com will help restore full or near-full function in your knee while reducing the risk of future injuries or complications. Given the severity of a patella tendon rupture and its impact on knee function, rehabilitation can be lengthy, often taking over 6 months. However, with dedicated adherence to your physiotherapy programme with acephysiosports.com, recovery time can be significantly shortened, helping you regain strength, mobility, and confidence in your knee more effectively.
1-2 weeks
In the initial stages of your recovery after a patella tendon repair, the main goals of your physiotherapy with acephysiosports.com will be to control pain and swelling, maintain mobility of the patella (kneecap), preserve strength in the hip and ankle of your injured leg, and maintain strength in the muscles of your uninjured leg. Your physiotherapy programme at this stage will include:
- Pain and swelling management using modalities such as ice, compression, and elevation.
- Gentle patella (kneecap) mobilisations to maintain movement.
- Isometric exercises for the quadriceps, hamstrings, and gluteal muscles.
- Strengthening exercises for the hip and ankle of the injured leg.
- Strengthening exercises for the opposite uninjured leg to provide support.
