Is other joint damage common?

Inside the knee joint are pieces of cartilage called menisci. The menisci act as shock absorbers between the femur and tibia. Many times these cartilages are also damaged when the cruciate ligaments rupture. They are usually repaired at the same time as the ligament surgery.

Is an operation always necessary?

Dogs under 10kg may improve without surgery, but joint damage and arthritis will continue to develop if the joint is not stable. These patients are often restricted to cage rest for two to six weeks. Dogs over 10kg usually require surgery to heal. Unfortunately, most dogs will eventually require surgery to correct this painful injury.

What does surgery involve?

There are various techniques available to replace the action of the cruciate ligaments. These surgeries most often involve the placement of artificial ligaments along the outside of the knee joint. There are newer surgical techniques available including Tibial Plateau Leveling Osteotomy (TPLO) or Triple Tibial Osteotomy (TTO) that are especially beneficial for larger, more athletic dogs. Your veterinarian will discuss with you the best treatment option for your pet.

Is post-operative care difficult?

It is important that your dog have limited activity for six to eight weeks after surgery. Provided you are able to carry out your veterinarian’s instructions, good function should return to the limb within three months. Unfortunately, regardless of the technique used to stabilise the joint, arthritis is likely to develop in the joint as your dog ages. Weight control and nutritional supplements such as glucosamine / chondroitin or synovan injections may help delay the onset of arthritis in your pet. Many dogs will receive physical therapy after the surgery to speed recovery and reduce complications. Your veterinarian will discuss your pet’s recommended post-operative care with you prior to surgery.

Is obesity such a problem?

Obesity can result in cruciate ligament rupture. If your dog is overweight, the recovery time will be much longer. Obesity also increases the risk of injury to the other knee. Weight loss is as important as surgery in ensuring rapid return to normal function.

How can you stop this from happening to your pet?

Tearing of the cruciate ligament occurs when the ligament is diseased and/or there are excessive forces placed on the knee. It most commonly occurs in overweight dogs when they are exercising. You can help to prevent this by keeping him/her at a healthy weight and managing any arthritis or joint pain that they may develop early on.

Ankle sprains are common injuries that occur among people of all ages and at all activity levels; in fact, they are the number one reason for missed participation in athletics.

An ankle sprain occurs when the strong ligaments that support the ankle stretch beyond their limits and tear. The severity of a sprain can vary greatly depending on the number of ligaments involved and the extent to which the ligaments are torn.

Most sprains heal with conservative treatments like ice, elevation, over-the-counter medications, and simple rehabilitation exercises. However, if your ankle remains swollen or painful for several weeks despite conservative treatments, or if you have difficulty putting weight on your ankle, you may need to be evaluated to ensure that you do not have a severe ankle sprain or fracture.

If symptoms do not improve despite non-operative treatment, you may need surgery to repair or reconstruct the injured ligaments.

Without proper treatment and rehabilitation, a chronic or untreated severe sprain can weaken your ankle, making it more likely that you will injure it again. Repeated ankle sprains can lead to long-term problems, including chronic ankle pain, arthritis, and instability.

Ligaments are strong, fibrous tissues that connect bones to other bones throughout the body. Numerous ligaments in the ankle help to keep the bones in proper position and stabilize the joint. Joint stability is important for all types of activities, including standing, walking, and running.

Around 90% of ankle sprains involve an inversion injury (the foot turns inward) to the anterior talofibular (ATFL) and calcaneofibular (CFL) ligaments — the lateral ligaments on the outside of the ankle.
The less common medial ankle sprain is caused by an eversion injury (the foot turns out) to the deltoid ligament on the inside of the ankle.

Sprains can range from tiny tears in the fibers that make up the ligament to complete tears.

If there is a complete tear of the ligaments, the ankle may become unstable after the initial injury phase passes. Over time, this instability can result in damage to the bones and cartilage, the smooth lining of the joint.

Patients often recall a twisting injury to their foot or ankle. If there is severe tearing of the ligaments, you might also hear or feel a pop. Sprains may occur unexpectedly during many different activities, such as:

Walking or exercising on an uneven surface
Falling down or tripping
Participating in sports that require cutting or jumping actions, such as trail running, basketball, tennis, football, and soccer

The types and severity of symptoms for a sprained ankle vary widely depending on the degree of the injury. Symptoms may include:

Pain, both at rest and with weightbearing or activity
Swelling
Bruising
Tenderness to touch
Instability of the ankle, or feeling that your ankle is giving out

Symptoms of a severe sprain are similar to those of a broken bone and require prompt medical evaluation.

Physical Examination

Your doctor will diagnose your ankle sprain by asking you questions about the injury and performing a careful examination of your foot and ankle. Due to the swelling and inflammation, this physical exam may be painful and often includes:

Observation. Your doctor will look at the injured ankle and compare it to your other ankle. Often, the sprained ankle is swollen and bruised over the injured ligaments.
Palpation. Tenderness is often limited to the area directly over the injured ligaments. Your doctor will gently press around the ankle to determine which ligaments are injured.
Range of motion testing. The doctor may move your ankle in different directions; however, it may be difficult to move a stiff, swollen ankle.
Stability testing. Your doctor may manipulate or pull your ankle in several directions in a controlled manner to assess the stability of the ankle joint.

Your doctor may be able to tell the severity of your ankle sprain based on the amount of swelling, pain, bruising, and stability. If you have difficulty bearing weight, or tenderness in the bones of the foot and ankle, you may need additional tests to rule out a fracture.

Imaging Tests

An ankle sprain is largely a clinical diagnosis based on how the injury happened, symptoms, and examination by a medical professional. Occasionally, imaging studies, such as X-rays and magnetic resonance imaging (MRI) scans, are obtained to rule out a fracture or other injury to the nearby tendons and cartilage.

X-rays. X-rays provide images of dense structures, such as bone. Depending on your symptoms and examination, your doctor may order X-rays to evaluate the bones in your ankle and foot. Severe ankle sprains can have a similar degree of pain, bruising, and swelling as a fracture, making it difficult to distinguish between the two.

Stress X-rays. In addition to plain X-rays, your doctor may also order stress X-rays. These images are taken while the ankle is being pushed in different directions in a controlled manner. Stress X-rays help to show whether the ankle is unstable because of injured ligaments.

Magnetic resonance imaging (MRI) scan. An MRI scan is not required to diagnose ankle sprains. Your doctor may obtain an MRI:

To evaluate other structures, such as cartilage and tendons, around the ankle
If you exhibit signs of a high ankle sprain — an injury to the ligaments and structures connecting the bones of the lower leg (tibia and fibula)
If your symptoms persist beyond 6 to 8 weeks after the injury despite conservative treatment

After the examination, your doctor will determine the grade of your sprain to help develop a treatment plan. Sprains are graded based on how much damage has occurred to the ligaments.

Grade 1

Slight stretching and microscopic tearing of the ligament fibers
Mild tenderness, bruising, and swelling around the ankle
Typically no pain with weightbearing
No instability on examination

Grade 2

Partial tearing of the ligament
Moderate tenderness, bruising, and swelling around the ankle
Mild pain with weightbearing
Slight instability on examination

Grade 3

Complete tear of the ligament
Significant tenderness, bruising, and swelling around the ankle
Severe pain with weightbearing
Substantial instability on examination

Nonsurgical Treatment

Nearly all isolated low ankle sprains can be treated without surgery. Even a complete ligament tear (Grade 3) will heal without surgical repair if it is immobilized and rehabilitated appropriately.

A three-phase program guides treatment for all ankle sprains — from mild to severe:

Phase 1

Includes a short period of immobilization, rest, and ice to reduce the swelling.
Early weightbearing as tolerated is typically recommended during this phase.
For a Grade 2 sprain, a removable plastic device, such as a walking boot or aircast brace, can provide support.
Grade 3 sprains may require a short leg cast or cast-brace for 10 to 14 days.
In most cases, swelling and pain will last 2 to 3 days. Walking may be difficult during this time, and your doctor may recommend that you use crutches as needed.

Phase 2

Is typically initiated early and includes functional rehabilitation that focuses on:
- Range of motion exercises
- Isometric strengthening
- Proprioception (balance) retraining exercises
It is important to discontinue ankle immobilization during this phase to avoid stiffness.

Phase 3

Includes advancement of strengthening and proprioception exercises and the gradual return to pre-injury activities. This begins with activities that do not require turning or twisting the ankle, followed later by activities that require sharp, sudden turns (cutting activities), such as tennis, basketball, or football.
Early return to sporting and work activities may require ankle taping or bracing.

This three-phase treatment program may take just 2 weeks to complete for minor sprains, or up to 6 to 12 weeks for more severe injuries.

Home Treatments

For milder sprains, your doctor may recommend simple home treatment.

The RICE protocol. Follow the RICE protocol as soon as possible after your injury:

Rest your ankle by not walking on it or returning to sport.
Ice should be immediately applied to keep the swelling down. It can be used for 20 to 30 minutes, 3 or 4 times daily. Do not apply ice directly to your skin.
Compression dressings, bandages, or ace-wraps will immobilize and support your injured ankle. The compression may also help with swelling.
Elevate your ankle above the level of your heart as often as possible during the first 48 hours. Elevation also helps control the swelling.

Medication. Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen can help control pain and swelling. Because they improve function by both reducing swelling and controlling pain, they are a better option for mild sprains than narcotic pain medicines.

Physical therapy. Rehabilitation exercises during phase 2 and 3 of recovery are used to improve flexibility, strength, and proprioception (balance).

Early motion. To prevent stiffness, your doctor or physical therapist will provide you with exercises that involve range-of-motion or controlled movements of your ankle without resistance.
Strengthening exercises. Once the swelling and pain have improved, exercises to strengthen the dynamic stabilizers (muscles and tendons) in the front and back of your leg and ankle will be added to your treatment plan. Water exercises may be used if weightbearing strengthening exercises, such as toe-raising, are too painful. Exercises with resistance are added as tolerated.
Proprioception (balance) training. Poor balance often leads to repeat sprains and ankle instability. A good example of a balance exercise is standing on the affected foot with the opposite foot raised and eyes closed. Balance boards are often used in this stage of rehabilitation.
Endurance and agility exercises. Once you are pain-free, other exercises, such as agility drills, may be added gradually. Running in progressively smaller figures-of-8 is excellent for agility and calf and ankle strength. The goal is to increase strength and range of motion as balance improves over time.

Surgical Treatment

Surgical treatment for ankle sprains is rare.

Surgery is reserved for injuries that fail to respond to nonsurgical treatment, and for patients who experience persistent ankle instability and pain after months of rehabilitation and nonsurgical treatment.
Surgery may also be indicated for some high ankle sprains with instability of the ankle syndesmosis.
Sometimes surgery is recommended if a severe ankle sprain is associated with additional injuries, such as an ankle cartilage injury or tendon rupture.

Types of surgery

Surgical options include:

Arthroscopy. During arthroscopy, your doctor uses a small camera, called an arthroscope, to look inside your ankle joint. Miniature instruments are used to remove any loose fragments of bone or cartilage, or parts of the ligament that may be caught in the joint.
Repair/reconstruction. Your doctor may be able to repair the torn ligament with stitches or sutures. In some cases, they will reconstruct the damaged ligament by replacing it with a tissue graft obtained from other ligaments and/or tendons found in the foot and around the ankle.

Recovery

Immobilization. There is typically a period of immobilization after surgery. A cast or protective boot is applied to protect the ligaments. Be sure to follow your doctor's instructions about how long to wear the protective device; early mobility or weightbearing can re-tear the repair or the reconstructed ligament.

Rehabilitation. Rehabilitation after surgery involves restoring strength and range of motion so you can return to pre-injury function. The length of time you can expect to spend recovering depends on the extent of injury and the surgery that was performed. Rehabilitation may take weeks to months.

Outcomes for ankle sprains are generally quite good. With proper treatment and rehabilitation, most patients are able to resume their day-to-day activities after a period of time. Successful outcomes and return to activity depend on:

The grade of the sprain.
Whether there are other injuries.
The patient's commitment to rehabilitation exercises. Incomplete rehabilitation is the most common cause of chronic ankle instability after a sprain. If a patient stops doing the strengthening exercises, the injured ligament(s) will weaken and put the patient at risk for future ankle sprains.

Chronic Ankle Sprains

Once you have sprained your ankle, you may continue to sprain it if the ligaments do not have time to completely heal. This can happen if you return to work, sports, or other activities before your ankle heals and is rehabilitated. It may be difficult to determine whether the ligament is completely healed, but symptoms (pain and swelling) can often guide the advancement of physical therapy and function.

If pain continues for more than 4 to 6 weeks, you may have a chronic ankle sprain. Things that tend to make an already sprained ankle worse include:

Stepping on uneven surfaces
Participating in sports that require cutting actions, or rolling and twisting of the foot

Abnormal proprioception — a common complication of ankle sprains — can also lead to repeat sprains.

Reinjury may result in chronic instability, pain, and damage to the underlying cartilage and bones.

The best way to prevent ankle sprains is to maintain good muscle strength, balance, and flexibility. The following precautions will help prevent sprains:

Warm up thoroughly before exercise and physical activity.
Perform strengthening exercises to enhance your ankle stability.
Pay careful attention when walking, running, or working on an uneven surface.
Choose footwear with appropriate support for your activity.

What is it called when a ligament is torn at a joint?

The human body has more than 900 ligaments that help connect bones, joints and organs and hold them in place. A ligament can be overstretched or torn, called a sprain.

What is a strain vs sprain?

Difference Between Sprains and Strains The most common type of sprain is when ligaments in the ankle are overstretched. If you “turn” an ankle, the result is often a sprain. A strain is similar to a sprain, except that with strains the muscles and tendons are majorly affected, rather than ligaments.

What causes ligament tearing?

Common causes of ligament tears are twisting body parts or hard or awkward landings. Tears often happen when ligaments are stretched fully and then encounter some form of impact or trauma. Ankle sprains, a mild torn ligament in the ankle, can happen when you are walking or running, land awkwardly, and twist your ankle.

What do you call an overextending or tearing of ligaments?

Sprain: Ligament injury A sprain involves the overstretching or tearing of the ligaments, which are the fibrous connective tissues that connect bones to each other and stabilize them.
