Knee Tightness After Resuming Exercise: Causes and Remedies - Rehabilitation

Knee tightness


Hello Doctor, I started exercising on May 17 after not being active for a year.
The exercises are mainly core types, including squat jumps and similar activities, and I maintained this routine for a little over a month.
Two days ago, I suddenly felt tightness in my left knee, but there is no pain when walking, and it doesn't affect my mobility.
Yesterday, I noticed some areas on my knee that feel slightly bruised.
I have been applying ice and using topical ointment.
I would like to ask if my treatment approach is correct and whether the tightness could be due to a long period of inactivity or improper posture.
Thank you.

Dr. Li Yanheng reply Rehabilitation


If ice therapy has been applied for more than two days without swelling, heat therapy can be used instead, and rehabilitation exercises may begin.
This is often caused by patellofemoral syndrome due to insufficient strength in the thigh muscles.

Hello! It’s great to hear that you’ve started exercising again after a long break. Your experience of knee tightness after resuming exercise is not uncommon, especially after a year of inactivity. Let's delve into the potential causes of your knee tightness and discuss appropriate remedies.


Causes of Knee Tightness
1. Muscle Tightness and Weakness: After a prolonged period of inactivity, your muscles, particularly those around the knee (like the quadriceps, hamstrings, and calf muscles), can become weak and tight. When you suddenly engage in physical activity, these muscles may not be able to handle the stress, leading to tightness.

2. Improper Form: If your exercise technique is not correct, it can place undue stress on your knees. For example, during squats or jumps, if your knees are not aligned properly with your toes, it can lead to tightness and discomfort.

3. Overuse: Jumping back into exercise too quickly can lead to overuse injuries. Your body needs time to adapt to the new physical demands, and pushing too hard can result in tightness or even minor strains.

4. Inflammation: The bruised feeling you described could indicate mild inflammation in the knee joint or surrounding tissues. This can happen due to repetitive stress or minor injuries that may not be immediately apparent.


Remedies and Management
1. Rest and Recovery: It’s essential to allow your body to recover. If you experience tightness, consider taking a break from high-impact activities like jumping or squatting. Instead, focus on low-impact exercises such as walking or swimming, which can help maintain fitness without stressing the knee.

2. Ice Therapy: You mentioned using ice, which is an excellent way to reduce inflammation and tightness. Apply ice to the affected area for 15-20 minutes several times a day, especially after activity.

3. Gentle Stretching: Incorporate gentle stretching exercises for your quadriceps, hamstrings, and calves. Stretching can help alleviate tightness and improve flexibility. Hold each stretch for about 15-30 seconds without bouncing.

4. Strengthening Exercises: Once the tightness subsides, gradually incorporate strengthening exercises for the muscles around the knee. Focus on low-impact movements that target the quadriceps, hamstrings, and glutes. Exercises like leg raises, wall sits, and step-ups can be beneficial.

5. Proper Technique: Pay attention to your form during exercises. Consider working with a trainer or physical therapist who can provide guidance on proper technique and help you develop a balanced workout routine.

6. Gradual Progression: When returning to exercise after a long break, it’s crucial to progress gradually. Start with shorter sessions and lower intensity, then slowly increase the duration and intensity as your body adapts.

7. Consult a Professional: If the tightness persists or worsens, it may be wise to consult a healthcare professional, such as a physical therapist or orthopedic specialist. They can assess your knee and provide tailored advice and treatment options.


Conclusion
In summary, the tightness in your knee after resuming exercise could be due to a combination of muscle tightness, improper form, overuse, or mild inflammation. Your current approach of icing and applying topical treatments is appropriate. However, ensure you allow adequate rest and gradually reintroduce exercises while focusing on proper technique. If symptoms persist, seeking professional advice is advisable. Remember, listening to your body is key to a successful and sustainable return to exercise. Good luck, and take care!

It is possible that intense exercise caused this. You can rest for a few days and then apply heat to see if it improves. It is generally advisable to warm up before engaging in vigorous exercise by doing some light activities; otherwise, injuries can easily occur.
